Bosch dishwasher error code e01
If you see a E01 error message on your Bosch dishwasher’s display, and the water is not reaching the set temperature, there is a problem with the heating element. This is no reason to worry: the system is just notifying you of the malfunction and telling you where to look for a solution to resume the washing cycle.
There is a troubleshooting guide in your instruction manual, where all error messages are listed and supplied with descriptions and explanations. Just find the E01 in the list aand read what you can do about it.
Why does the e01 error appear on a Bosch dishwasher? What does it stand for?
Whenever you see the E01 error on your dishwasher’s display, check the heating element. Not unlikely, the problem results from loose connections or burnt contacts preventing the element from receiving the right signal from the main control board. Also, the heating element itself could have gone faulty due to calcification. This often happens in regions with hard water.
In the latter case, you will need to replace the entire element, because it cannot be disassembled, so there are no parts for it available.
How do I clear the e01 error in my Bosch dishwasher?
It is important to know why exactly the error has appeared. It could have been caused by a glitch, so try resetting prior to doing any serious work on your dishwasher.
- Disconnect the machine from power and wait 10-15 minutes;
- Run the cycle and check if the error comes back. If it does, do the following:
Please, note: the heating element is quite expensive. Please, be sure you really need to replace it.
- Unplug the dishwasher and disconnect the inlet and drain hoses.
- Remove all baskets from the inside.
- Remove the drain filter.
- The heating element and branch pipes are held by a helix: unscrew it.
- Turn the machine upside down and unscrew the back cover.
- Remove the wiring from the pump, turn it counterclockwise and pull it out.
- Detach the rubber mount under the heating element.
- Disconnect all wires and pipes and remove the heating element.
- Place the new one instead and carry out the procedure in the reversed order.
As you can see, being consistent and careful could help you do a big thing without using professional help. Now you know how to fix the E01 error.
Bosch dishwasher error code e02
The E02 error code appears on the display of a Bosch dishwasher when the thermistor (temperature sensor) fails. This sensor regulates the work if the heating element and is directly involved in heating up the water. The error often occurs when the thermistor works at maximum power.
How Do I Test the Temp Sensor?
To ensure that it is the thermistor that causes the problem, you should carry out a diagnostic procedure. Here is the algorithm:
- Unplug your dishwasher and disconnect the inlet and drain hoses;
- Open the door and remove all baskets;
- Disassemble the bottom sprinkler and remove the garbage filter;
- Turn the dishwasher upside down and remove the side panels;
- Disconnect the branch pipe and remove the machine’s bottom;
- Disconnect the power supply wires from the thermistor;
- Clean all contacts and check the sensor for continuity using a multimeter. It should be around (~ 55 kΩ at 21 ° C). The sensor’s resistance of changes as it operates and the water heats up.
- If the thermistor proves faulty, replace it. Make sure that the wiring is ok. Do all the above steps in the reversed order.
Thermistors cannot be repaired, so buying a new one is the only optimal thing you can do. Once the part is replaced, the error will go away.
Bosch dishwasher error code e04
E04 is another error message on the Bosch dishwasher list: it signals a water flow sensor failure. Not unlikely, the inlet valve or hose are blocked or clogged.
What does it stand for?
The error can appear when the flow sensor or injectors go faulty. The water may have difficulty passing through the sprinkler holes due to a clog or calcium buildup, if the water is hard in your area.
This is a kind of problem, which can be fixed without calling a professional technician. Please, follow the advice and be consistent in doing any work on your device.
Please, note that this may not even be a water sensor problem. This could be a glitch of some kind of software error. In this case, a simple reset can be a solution:
- Unplug the dishwasher;
- Wait for 10-15 minutes. You can use the time to check the inlet hose tor bends, loops and clogs; also, check the inlet valve.
- Plug the machine back in and run a cycle.
If it was due to a glitch, the error should go away. If it does not, do the following steps:
- Check the sprinkler.
- If it is dirty, remove it.
- Rinse it thoroughly under running water.
- Check the holes and clean them with a toothpick, if necessary.
Choose a type of salt for your dishwasher specified in the instruction manual. Thus you can avoid calcification of the machine’s components.
I have cleaned all parts, but the error appears again: what to do?
If it does, the flow sensor needs to be replaced. It is imperative that your Bosch dishwasher feature a non-faulty flow sensor, because it controls the amount of water coming in and ensures safe functioning of the unit. In some models, the sensor substitutes a pressure switch. In case the water exceeds the admissible level, the sensor sends a signal to the main control board to stop the intake of water.
When choosing the sensor or any other spare part, please, note the model and mark of your device to ensure that the new component will work for it.
Such errors often occur due to lack of regular care or maintenance. Filters must be checked and cleared every month. Last, but not least, is the use of a correct type of salt to reduce the hardness of water and prevent the buildup of mineral scale.
Bosch dishwasher e06 error code
The E06 error message on the display signals a problem in the water turbidity sensor (also known as the Aqua Sensor).
The turbidity is measured with the help of tiny particles of dirt, food and debris floating in the water. This function helps you regulate water consumption and intensity of work and thus reduce electricity intake.
Why check water quality and how does the turbidity sensor work?
The device is a combination of a phototransistor and an infrared photodiode placed on a board opposite each other. The board has a light-proof U-shaped casing. The photodiode emits a beam, which passes through the water and hits the phototransistor. If the water is not contaminated, the sensor signals the system to reuse this water instead of taking on new water and to reduce the rinsing.
If the water is not clear, the stuff contained in it blocks the beam, and it fails to activate the phototransistor. The Aqua Sensor’s microchip signals the lack of signal to the main control board, which perceives it as a high turbidity level. The system launches one or several rinse cycles until the water reaches a purity level, which the sensor evaluates as optimal. Thus the machine can save about 4 liters of water per wash with the quality of washing intact.
Please, note: minerals building up on the sensor’s components, as well as detergents in the water, will affect the sensor’s sensitivity. Please, check the device at least once a month.
The Aqua Sensor is found in the dishwasher’s bottom part, and it will be visible when the left-hand side of the case is removed. The sensor is integrated into the circulation pump’s connector. In case you need to replace the sensor, you just need to pull it out of the connector. Sometimes turbidity sensors fail due to burned contacts and can be repaired.
Bosch dishwasher error code e07
The E07 error appears when the hole, through which water gets into the system from the hopper, closes and/or the filter gets clogged. In most cases, the solution is easy: check the bunker and/or filter and clean it. To clean the filter, drain all water from the machine, remove the pallets, get to the filter and remove it. Most likely, the filter is blocked by food particles. Remove them and rinse the filter under running water.
It is highly advisable to remove large pieces of food from dishes, cups and silverware, prior to loading them into your dishwasher, and rinse them. This will prevent clogging and keep your dishwasher working non-stop. Please, use the right types of detergents.
It is also possible that the error was caused by improper stacking of dishes. Please, refer to the manual and restack the dishes.
Bosch dishwasher error code e09 (e9 or 09)
If you see this error code on your Bosсh dishwasher’s display, there is a problem with the heating element.
What does it mean?
Most likely, part of the heating element is down and needs to be replaced. Dishwashers’ heating elements are different from those of washing machines: they are attached to the recirculation pumps and heat up water.
About 90% of all cases of E9 appearing result from failing heating elements; the remaining 10% c over:
- Poor wiring
- Faulty temperature sensor
- Incorrect functioning of the main module
Why do heating elements fail?
Please, remember these main causes unless you want to face the problem ever again
- There is a leak. Over time, rubber gaskets and seals wear off and cause leaks. Water fills the sump tray. The heater and motor are located in that area. Not infrequently, pipes and joints become unsealed. The problem requires a complex check, which should involve all pipes, tubes and hoses.
- The filter has gotten clogged. It needs to be cleaned regularly. If you do, you can prevent lots of issues and errors not related to this one. Clogs slow down the circulation of water and cause the system to overheat. As a result, the E9 code appears. To eliminate the problem, open the bottom door, remove the filter and clean the filter mesh in running water. No matter how hard you try to remove food particles from your dishes, they do get into the machine and block it from time to time.
How do I eliminate the problem?
First, you should make sure it is not a program fault. If this is the first time you see this code, rreset the program:
- Unplug your dishwasher;
- Wait 10-15 minutes;
- Plug it back in.
If it does not reappear, you have solved the problem. If it does, you need to disassemble your dishwasher and replace the heating element.
Bosch dishwasher e13 error code
Advanced Bosch dishwashers feature a number of sensors, which regulate their work and ensure optimal general functioning. For example, a temperature sensor signals a malfunction by displaying the E13 error when the water entering the dishwasher is too hot. Particularly, the error will appear if you choose to connect your dishwasher to hot water.
As water enters the dishwasher, it is usually heated up to 65oC-75oC. Once the temperature exceeds the limit, the sensor signals the main control board to block the cycle and display the E13 fault code.
Would it be good to connect the dishwasher to hot water?
In order for the dishwasher to operate safely and properly, the water temperature should stay within the limit. If the water entering it does not exceed it, the machine will function well. However, most frequently, hot water in the household water supply system has a higher temperature. This causes errors and reduces the unit’s life. Besides, using cold water ensures a better economy: having to repair your dishwasher would be way more expensive than consuming some 1.5 kW of energy with cold water fed into the machine. The water is heated up by a heating element.
Also, hot water often has impurities, which are not typical of cold water. These may affect the work of the ion exchanger – a device, which is involved in monitoring the water’s chemical composition. Hot water can cause the exchanger to break down.
Other minuses of using hot water
- The impurities contained in hot water can affect the input filter. You will have to remove and clean it too frequently.
- Hot water is harder than cold water and therefore requires the use of a lot of detergents, which affect its parts.
- There are detergents, which retain their effect at a set temperature or in a particular heating mode. Once they get into hot water, they lose their properties. This affects the general quality of washing.
Bosch dishwasher error code e14
Today’s Bosch dishwashers feature running water heaters, through which cold water runs and heats up to the set temperature. Also, they are equipped with pressure switches. It is a device, which is controlled by the main control board and is activated when the amount of water deviates from the specified level, displaying the E14 error message. Some Bosch dishwashers use water flow sensors instead of pressure switches, and they perform a similar function.
What causes the problem
The self-diagnostic system helps users target issues and find solutions. There is an error code referring to malfunctions that occur within particular components and systems, so users know where to look for a problem. The E14 fault code indicates a problem with the flow sensor – a device, which monitors the amount of water in the tank. It is used in machines that use the flow-through water heating techniques and it stands in for a pressure switch.
However, this is not necessarily the sensor itself; this may be a connection failure, as connections often go loose and contacts may burn.
Here are the most common causes of the E14 error:
- Too low or too high pressure in the system.
- Faulty inlet valve.
- Burnt electronic control board.
Next comes a step-by-step instruction on clearing the error and getting the dishwasher to work normally again.
Tilt the dishwasher 15-20 degrees to the left for several minutes. If it does not work, reset the software. Do the following steps:
- Cut off power and wait 10-15 minutes;
- Plug it back in and try a cycle.
If the error appears again, check the flow sensor. If it proves faulty, do not try to repair it. Order a new one and replace it.
Check the inlet hose and the inlet filter:
- Disconnect the hose;
- Rinse the hose and the filter under running water.
Check the inlet valve. In most Bosch dishwashers it is located in the bottom section. However, in some models it is installed in the top or side section. Check the diagram to determine its exact location.
How to replace the inlet valve:
- Disconnect the wiring;
- Undo the screw, which holds it in place.
- Remove the faulty valve.
- Replace it with a new one.
Prior to disassembling the unit or doing any work on it, make sure it is disconnected from the mains!.
If you see any signs of damage in the main control board, do not try to fix it yourself. It is advisable to trust a qualified technician to diagnose and repair the main control board.
Please, be consistent in finding the cause of a breakdown and eliminating it.
Bosch dishwasher error code e15
If the e15 error code appears on the display, it means that the AquaStop system has been activated. This is quite easy to clear.
The system’s algorithm is simple: if there is a leak, the water accumulates in a sump tray at the bottom. Once there is 0.2 liters of water, a float activates a micro switch. It cuts off electricity supply to the safety valve, so it closes right away and blocks water supply until the problem is fully solved. The excess water is drained from the base of the machine automatically.
How do I treat this problem?
You can clear the е15 error in the following way:
- Dry the sump tray by simply tipping the machine. Provide a container for the water.
- Do not run the machine until it dries completely. In a well-heated room, 24 hours will be quite enough for the unit to dry up.
- Clean the drain system from clogs. To do so, open the filters and check the drain line. Remove clogs or foreign objects, if any.
Once you have carried out all these steps, you can start operating your dishwasher again.
Bosch dishwasher error code e16
If you see the E16 error message on the display, the dishwasher is getting more water than specified by the cycle. In other words, the machine fails to control water intake. Not unlikely, the inlet valve is not closing properly due to a clog or damage. Here is a list of steps, which you should do to resume the control over water intake:
- Check the inlet valve and clean it, if necessary.
- Drain all water from the machine and check the water flow sensor. Switch off the dishwasher.
- If the problem occurs in the middle of a cycle, this may be due to excess suds in the system.
If the problem does not go away after you have taken the steps described above, call your local technical service.
Prior to doing any work on the unit, make sure the water supply is ok and there is water in the plumbing system. Be sure that the water tap near the machine is open and functional. Check the inlet hose for clogs, as well as for loops, twists and bends and eliminate them, if any.
Checking the Inlet Valve
The inlet valve is a crucial component, as it controls the flow of water in the dishwasher, as it enters the system under pressure. The main control board commands the valve to let in a specified amount of water, depending on the type of cycle. The control module can command it to close/open 2-8 times over a cycle.
The inlet valve may stop functioning due to a problem in the main control board or its wiring, or a clog or damage in itself.
As required by a wash cycle, or in case of emergency, the main control board may shut off the inlet valve and block the intake of water. If your dishwasher is taking too much water, this may be due to a faulty inlet valve.
Check the valve’s coil for continuity using a multimeter. It should read between 500 and 1500 ohms. If the coil meets this characteristic, the electrical part of the valve is all right.
Next thing you do is look for mechanical damage. If your machine suddenly fills slowly, most likely, it is clogged. If the valve is relatively new, remove the debris. If it is old, it is recommended to replace the valve.
If the tank is filling too rapidly and overflowing, most likely, the valve is not closing properly. To check that, open the dishwasher door a few times during the water fill cycle. If the water does not stop, replace the inlet valve.
If there is still no water in the dishwasher, please, check the water tap and ensure it is on. Check the water pressure in your plumbing system and make sure it meets the value specified in the manual.
Check the float and be sure it moves freely up and down. The float switch should produce clicks. If there are not any, check the float switch’s contacts for continuity. If there are no problems with the switch, this may be due to a filling switch malfunction.
Fixing the Inlet Valve In a Bosch Dishwasher
If the machine is not getting water:
- Check the connection to the water supply system.
- Make sure that the timer is functional.
- If the water supply and the timer are working properly, check the inlet valve. It is located right under the dishwasher tank. It could have stopped functioning due to debris coming in from the water supply system or calcification. Remove the valve filter using a screwdriver, then rinse it out properly. Put it back in its place and turn on the water supply tap.
- If the machine uses a solenoid valve, test it with a screwdriver to ensure that it is OK.
- If the filling issue persists, check the solenoid for continuity using a volt-ohm-milliammeter (VOM). It should read about 100 ohms to 1000 ohms. If it does, the solenoid is functional. If the readings exceed 1000, the solenoid is faulty and needs to be replaced.
- Please, be sure that the new solenoid is of the same size and type as the original one. Refer to the instruction manual.
Checking the Inlet Pressure Switch
The pressure switch’s function is regulating water level in the dishwasher’s chamber. A faulty pressure switch can cause either excess or lack of water in the machine.
Compare the actual amount of water to that required by the wash cycle. If there is a great difference, the switch must be faulty. Most likely, your dishwasher will display the E14 or E04 (rarely) error code, as it refers to this particular problem.
Bosch dishwashers come with pressure sensors of two types:
To check the functioning of a mechanical pressure switch, use your ears. It should produce characteristic clicks. Read the instruction manual, locate the part and listen. If necessary, refer to the troubleshooting guide. Checking an electronic pressure switch requires a bit of experience and, most likely, professional help.
Replacing the sensor
The procedure includes the following steps:
- Remove the dishwasher’s back panel.
- Disconnect the pressure hose under the pressure switch.
- Disconnect the machine from the mains, water supply and drain system.
- Pull out the connector.
- To assemble the new sensor, do these steps in the reversed order.
When you have finished the installation of the new part, make sure that everything works correctly. Run a wash cycle and check the water level. If it is ok, there will not be error codes flashing on the display, and the machine will work properly. If not, address a professional technician.
Bosch dishwasher e17 error code
The E17 fault code signals a high water pressure in the plumbing system. Most dishwashers require that water pressure stay within the range of 0.03 to 1 MPa. In this case, it will work effectively. You can reduce pressure by half-closing the water supply valve. Check water pressure in your system regularly. If it is always higher than it should be, use devices, which are intended for reduction of pressure in dishwashers.
Some models feature a gasket, which lowers water pressure. It is located on the inlet hose at the end of the inlet valve.
It is also possible that the inlet valve or flow sensor is defective. These parts cannot be repaired and need to be replaced.
Bosch dishwasher error code e19
Although the E19 error is often believed to be caused by a problem in the circulation pump, particularly its winding, in most cases it is not.
Most likely, the recirculation valve (also referred to as the ‘drain valve’) is defective. If the error appears on the display, please, check the recirculation valve. Remove it and inspect the wiring.
Bosch dishwashers feature heat-exchangers, which are patented by the corporation. In most machines, exchangers are located near the left-hand wall of the cleaning chamber. Cold water gets into the machine and flows through the exchanger, which heats it up to a temperature set by a particular wash cycle. The temperature may change from one cycle stage to another. This makes Bosch dishwashers energy efficient.
Bosch dishwasher error code e20
If you see the E20 error code on the display, there is a problem with the circulation pump. Particularly, it could result from damaged winding or other parts.
Why the error occurs in Bosch dishwashers
Because the circulation pump does not break down often, it is advisable to check the drainage system. Most likely, the filter is clogged or calcified, or there is a foreign object blocking the pump’s impeller. In these cases, the E20 error code appears.
Why the circulation pump fails:
- There winding has been damaged due to a voltage surge.
- Electronic parts have been short-circuited due to water getting into them.
- The heating element has broken down.
Please, be consistent when checking all these systems and items.
Not unlikely, the error has resulted from a system crash. Reset the machine in the following way:
- Disconnect power;
- Wait 10-20 minutes;
- Restart the unit and see if the error appears again.
If it does, clean the filter and do the following:
- Open the dishwasher’s door and remove all baskets.
- Reach into the pan and unscrew the drain filter
- Rinse the filter under streaming water and, if necessary, use a brush.
- Remove the cover.
- Check the drain pump behind the filter.
- Dry the hole using a sponge.
- Undo the fixing screws.
- Make sure the impeller is spinning freely and remove obstructions, if any.
Make sure that the circulation pump is working. Normally, it produces a characteristic buzzing sound. If it is not, the unit is faulty. Disassemble the dishwasher and replace the pump. This should be done in the following way:
- Remove all baskets.
- Unplug the dishwasher.
- Put the machine on the back.
- Unscrew/unlatch the bottom panel.
- Check the wiring for loose connections and burns.
- Remove the heating element and the drain pump and check their functioning.
Use a multimeter to diagnose the parts. Check their contacts and measure continuity.
Bosch dishwasher e21 error code
The E21 error code refers to the pump. However, it can fail for different reasons. Here is a little insight into the problem.
Why the error appears
Once the E21 message appears on the display, the dishwasher will stop completely. The cycle is interrupted, and there will be dirty dishes and water in the chamber.
Why it happens
- The pump system is clogged heavily. It paralyzes or severely impedes the draining process.
- The pump’s impeller is worn out or blocked by a foreign object or debris.
Not unlikely, the impeller is blocked by hair and/or threads winding on the axis.
- The rotor is faulty. On some occasions, it can slow down or stop completely. Most likely, a part of it has worn out and needs to be replaced.
In cases whereby the error occurs, the main control board still controls the work of the pump. However, when there is a problem in the pump, it activates an algorithm, which stops it until the faulty part is repaired or replaced.
Getting to a clog inside the pump is quite a challenge: you cannot do it without disassembling the unit. First, it is possible to clean the dustbin and launch the device. This could increase the chance of water getting through the filter to the clog and clear it. However, if the clog is too hard, the pump will need to be removed. Clean the pump niche. Check the impeller to ensure it spins freely. Reassemble the dishwasher.
When you have removed the pump, please, check the impeller. Not unlikely, it is worn out and no longer functional. You can tell this by damaged blades. In Bosch dishwashers, impellers are removable and therefore can be replaced easily.
Also, the impeller may stop spinning properly because of threads, hair and food particles sticking to it. The blades can be fully intact. Clean the impeller’s blades and put it back in its place. Reassemble the entire unit and run a cycle again.
There is a lot of word about the absence of appropriate grease in pumps. This increases the likelihood of the E21 error, as the rotor begins to hitch or slow down. This increases the risk of a premature wear-out of its parts.
- Choose high quality grease.
- Remove the impeller.
- When greasing it, follow the instruction written on the tube or container.
- Replace the impeller and make sure it spins well.
Reassemble the unit and run a wash cycle to check the operation. If the problem is still there, call your local technical maintenance service.
Bosch dishwasher error code e22
Not infrequently, the E22 error code appears not long before the end of the cycle. Sometimes, a reset can be a solution. However, if there is a problem, the code will reappear pretty soon, and the machine will stop in the middle of a cycle. Most likely, the code signals that the sump tray is filled with water.
Causes of drain failures
- If food from the dishes gets into the filter, it may block the circulation. As a result, the water will not go down the drain hose and will fill the base.
- The drain hose is bad or kinked. If the E22 code is alternating with E24, it is very likely to be a hose issue. Also, it can be a pump failure.
- A faulty impeller. Debris may get stuck between the pump’s bushing and the impeller and block the pump.
How do I clear the Е22error?
The first thing you should do is check and clean the drain system. Remove and rinse the filters in running water. In Bosch machines, the filter is located at the bottom, and there is a mesh filter right above it.
Then check if the drain hose is positioned properly and it is free of damage or defects.
Check the impeller(s) and clean them from debris, if necessary.
In some case, the error results from rusty metal parts. Use anti-rust agents.
What if the code is still there?
If the hose, impellers and filters are all right, and the dishwasher won’t do its job, you have to dig deeper. Disassembling it is no great challenge, but you should be very careful.
Tip the dishwasher over and remove the sump tray. Unscrew the drain pump (near the heating element) and remove the wiring. Check it for debris, because it may block the process.
A close look and cleaning of every part of the device is a nice way to eliminate the error code and get your Bosch dishwasher going for a long time.
Bosch dishwasher error code e23
In most cases, the E23 error appears when we least expect. Most users choose to reset the unit by turning it off and on. If helps but for a couple of minutes. So, what causes this erroe message to appear?
Causes of the E23 error message
- Water is not draining from the machine. This should be considered the main reason.
- There is also a problem, which can be identified by the E14 error code: water gets into the pallet and triggers the Aquastop system.
Not unlikely, your machine will display E14, E18, E23 errors in turn every time you reset it. It if happens, there is definitely water in the tray.
- The control board is faulty, and it is causing the diagnostic system to fail. As a result, any of the errors mentioned in your troubleshooting guide can appear.
To diagnose faulty electronic components, you need to have specific skills and knowledge. It is highly advisable to contact an authorized Bosch Service Center.
The pan is filled with water
To check if there is water in the dishwasher’s pan, do the following: unplug and disconnect the washer. Get it out of the cabinet. Tilt it to the right side. The water that is filling the pan will flow out. Use tubs, rags and towels.
If there was a lot of water in the tray, there is a damaged hose or nozzle. Remove the pallet and inspect these objects in the dishwasher. Also, it is advisable to check seams inside the chamber. They may leak because of a factory fault. In this case, water will from the chamber and into the pan.
Make sure that the garbage filter is installed correctly. Many users fail to fix it properly after the standard cleaning procedure. This may cause leaks too. Also, check the door seal. Look at the bottom part very carefully. Not unlikely, it has worn out and not is letting water through, so it can drip on the floor or into the pallet. If the visual examination of the outer element does not reveal any damage, look inside. Remove the pallet and carry out the following steps:
- Remove the front panel and the decorative panel below.
- Close the door and remove the latches and the hinges’ protection.
- Remove the soundproofing.
- Undo the screws, which connect the pallet to the dishwasher’s body.
- Remove the mesh filter and clean it thoroughly.
- If necessary, remove the lower sprinkler.
- Remove the 4 screws in the garbage filter niche.
- Put the machine on the back.
- Be sure to remove all parts connecting the pallet to the body: hoses, nozzles, wires, etc.
- Pull the pallet very carefully.
- Check all hoses, pipes, wire harnesses, etc., and replace damaged parts, if any. Do not use electrical tape or pour sealants.
Most likely, the dishwasher has stopped draining due to a pump breakdown or damaged wiring/contacts. Also note that this can be due to a problem in the main control board. Disassemble the dishwasher as said above. You will see the pump on the circulation unit’s side. To remove it, disconnect the wires and half-turn it counterclockwise. Check the pump for continuity and compare the reading with that specified in the instruction manual. If the ohmage is under or over the optinal level, replace the pump. Also, the error can occur due to a supply wire issue. Check the line with the multimeter.
Most of the issues that cause the E23 error are easy to fix.
Bosch dishwasher error e24
Every time we see an error code (e. g. E24) flashing on the display, the dishwasher stops washing our dishes, and we panic: what’s happening???
What does it mean?
The E24 error code indicates a drain problem, and the manufacturer says it is due to a bent or clogged drain hose.
The E24 code refers to the following possible problems:
- One of the sensors is faulty, and it is just a question – which one?
- Faulty drain pump;
- Faulty main control board.
How do I clear it?
As long as the manufacturer uses this code to indicate a drain problem, let’s deal with clogs.
Clear the drain hose with a brush-tipped snake. Also, you can remove a plastic cover located beneath the filter, and access the drain pump’s gear. Examine it and clear debris, if any.
Important! There may be a clog at the junction point between the drain hose and the sewer outlet. It must be unclogged too.
Pumps get clogged too. When it happens, a pump stops draining water from the machine, and the E24 error appears. Clean the pump. To do so, you need to get inside your dishwasher.
Bosch dishwasher error e25
Seeing a Bosch dishwasher stop suddenly is frustrating. In fact, to clear the error, you must know what it means.
What does it mean?
For this German dishwasher, this error code indicates a clog in the sleeve, which is connected to the drain pump. In some models, this is just the end of a drain hose,, which is connected to the pump.
Another possible cause is blocked or uncovered drain pump.
It is clear that the blocking results from a foreign object or piece of debris getting into it. The absence of cover often causes the error, as clogs do.
Most likely, the error is caused by debris and food particles clogging the system due to failure to follow simple maintenance rules.
It happens when users fail to clear the system from fat for a long time.
Eliminate the cause
So, if your dishwasher has stopped and there is an error code indicating a clog, the first thing you should do is drain water from the base.
- Remove the lower arm.
- Pour the sump water into a separate container.
- Remove the filter cover.
- Remove the filter.
- Look inside and, if necessary, remove water using a piece of thick cloth.
- Remove the shutter, which covers the impeller, using long pincers.
- Examine the impeller, remove debris, and check the impeller’s functioning
- Put it back together and run the dishwasher to check its work.
If the problem persists, the drain sleeve or drain hose need to be cleaned.
If the pump is bad, what you’re going to do next depends on how bad it is. If the impeller is bad, replace it. However, if the coiling has burnt, the entire motor needs to be replaced.
Bosch dishwasher error code e27
Many users find it hard to figure out why the E27 error appears on the display.
What causes the E27 error and how to clear it?
Instruction manuals say that the E27n error message signals low voltage. Particularly, it drops below 220V (or 110V in some regions). Once it happens, the code appears and the dishwasher stops working. It is most likely to happen at night, when networks are most loaded. This prompts many household owners to use the delayed start function, which allows them to postpone the launch for several hours. The dishwasher will launch the chosen cycle automatically at the specified time and clean all dishes by the morning.
Another way to solve the voltage problem is using a voltage regulator.
Installing a voltage regulator
Choosing the right type of regulator is the hardest part of it. There are good reasons to connect a number of devices to one stabilizer. It will operate a dishwasher, a washing machine, a refrigerator, etc. easily. In this case, it is recommended to put a stabilizer on the household electricity supply system. Although this can be expensive, all your appliances and devices will be protected from power fluctuations.
Once you see the error message take steps to test voltage in your dishwasher and the house. Use an appropriate type of stabilizer. It will minimize the risk of electrical damage and serious material expenses.
Bosch dishwasher error code h01 (or h02)
Many owners of Bosch dishwashers feel confronted and confound when they see h01 (h: 01) or h02 (h: 02) on the display. They believe, these are errors. These are not. In fact, these messages denote delayed start time. If you have accidentally chosen the h01 (h: 01) or h02 (h: 02) messages, the wash cycle will begin in 1 and 2 hours respectively. The maximum delay time for Bosch dishwashers is 24 hours.
