Asko 1555 dishwasher troubleshooting

ProblemPossible CauseSuggested Remedy
Spotting and filmingHard waterUse the maximum recommended amount (3 tablespoons) dishwasher detergent. You may need a home water softener.
To remove hard water spots, try a vinegar rinse:
• Wash and rinse load as usual.
• Remove all metal items from dishwasher.
• Do not add detergent.
• Pour two cups of vinegar into a bowl and set it on the bottom rack of the dishwasher.
• Run the dishes through an entire wash program.
If the vinegar rinse doesn't work, repeat the above process substituting 1/4 cup citric acid crystals (available at most drug stores) for the vinegar.
Filter system No rinse aid Water not hot enough Too little waterWiping with a damp cloth should remove spots from metal items. For steriing and silver plated flatware, rub with a towel, or use a good cream silver polish.
Check filter system to be sure it is clean and properly installed.
Does the rinse aid dispenser need to be filled?( Note: Used only in hard water areas.)
Use the Temp Boost for best results when washing heavily soiled or greasy items, except for fine china and delicate crystal.
Check that the water valve is fully open. Make sure that the water pressure is between 18 and 176 PSI.
Dishwasher detergentCheck the filter in the inlet valve.
Use only the correct amount of dishwasher detergent according to the hardness of the water and the wash program you have selected. Do not use old or caked detergent. Store the dishwasher detergent in a dry place and in a closed container. Change the dishwasher detergent, if the result is still unsatisfactory.
Items not loaded properlyCheck that you have loaded the items. Do not overload. Make sure spray can reach all soiled surfaces.
Spray arms rotate poorly or stand stillCheck that both spray arms can rotate freely and that items do not obstruct the movement of the spray arms. Lift the arms and make sure that no grains of dirt etc. retard the rotation of the spray arms. If necessary, clear the obstruction, refit the arms and check that they rotate freely.
Make sure that the holes in the spray arms are not blocked by dirt. If necessary, clear the holes with a pointed object.
Strainer blockedCheck the strainer. Clean if necessary.
Excessive foam in the machineUse only dishwasher detergent. Too much rinse aid in final rinse cycle.
Flatware incorrectly loadedPay particular attention to spoons so that they do not nest in each other and prevent water penetration.
Small particles deposited on itemsSpray arm or arms not rotating freelyBe sure a utensil or handle has not prevented their turning.
DetergentUse only fresh detergent, stored in a tightly closed container in a cool dry place. Fill dispenser only when ready to start the dishwasher. Use the recommended amount of detergent, especially with hard water.
Low water pressure Improper loading of dishesCheck that the water valve is fully open. Make sure that the water pressure is between 18 and 176 PSI.
Load dishes to prevent water and detergent from being trapped in or between items. Water should circulate freely.
Marks and discolorationAluminum utensils rubbing against items during washingBe sure aluminum utensils, especially light weight foil-type pans, do not touch dishes.
To remove spots, use a non-abrasive cleaner.
Yellow or brown marksIron or manganese in waterTemporary solution: Pour 1 teaspoon to 1 tablespoon of citric acid crystals in instead of the prewash detergent directly on the inside of the door. Follow this prewash with a full detergent wash. Use the heavy wash program.
Copper with sterling silverPermanent solution: Install an iron removal system in the water supply.
Yellow film on sterling silver results when you wash copper utensils in the same load. Silver polish will usually remove this stain.
Tea or coffee (tannic acid)Tea or coffee can stain cups. Remove stains by hand, using a solution of 1/2 cup bleach and 3 cups warm water. (Do not use on sterling silver or silver plate.)
Discoloration of stainless steel, silver plate or sterling silverAllowing salty or acidic foods to remain on flatwareRinse flatware that is to stand several hours before washing.
Stainless steel contacting silverDo not put stainless steel and silver flatware in the same silverware basket compartment. Direct contact between these metals can cause permanent damage to silver.
Clean stained items with silver polish.
Do not use abrasives on stainless steel or silver.
Distortion of plasticsPlastic item has low heat tolerancePlastics vary in their ability to tolerate heat. Check washing instructions for all plastic items to be sure they are dishwasher safe. If they are, place in top rack, away from the heating element.
Marks on melamine and plasticsPorous materialUse a special cleaner for plastic.
DO NOT use bleach or scouring powder on these materials.
Cloudy film on glassware- etching of glassToo much detergent, especially in soft waterIf vinegar or citric acid rinse doesn 't remove film, the cloudiness is "etching". This is permanent. To prevent etching, use the least amount (one teaspoon) of recommended dishwasher detergent if you have soft water.
Use a good quality dishwasher detergent and rinse aid. Do not overload the machine. Water should circulate freely to assure adequate rinsing and draining.
Use drying without heat.
Rinse aid used with soft waterUse rinse aid in hard water areas only.
Dishes not dryNon-heated dryingBe sure to select heated drying for the driest results. Allow more drying time when using non-heated drying.
No rinse aidFill rinse aid dispenser. Rinse aids help dishes to dry faster. (Note: Used only in hard water areas).
Plastic itemsCertain plastic materials are difficult to dry. Plastics may need towel drying.
Improper loading or unloadingDo not overload or nest items. Be sure all surfaces drain well. Load items with concave bases so as much water as possible can run off. Unload the bottom rack first. Water from dishes in the top rack may be spilling into the bottom rack.
Water not hot enoughDishes washed with the HI water temperature setting will dry the fastest.
Dry cycle interrupted (Door opened too soon)If the door is opened during the heated dry cycle, the heating element does not come back on after the door is re-closed. Also, if dishwasher door is opened immediately after the dry cycle is completed and then shut again, the damper invent is closed, trapping warm humid air. It is best then to leave door open slightly.
Detergent left in detergent compartment (Detergent compartment will not open)Compartment cover blockedThe cover may not be opening because of improperly loaded items. Move dishes that may be blocking it.
Light cycle used Old detergentDetergent compartment door does not open during light cycle. Place detergent directly near bottom of inside surface of door.
If detergent is hard or caked in the box, throw it away. Use only fresh detergent Add detergent to dishwasher right before starting it.
Chipping or breaking of glasswareImproper loadingDo not overload. Load between prongs, not over them. Glasses loaded over prongs will not be supported and may chip or break. Make sure glassware is secure and can't come loose. Always use the top rack for delicate items. Use the delicate program for fine china.
Unusual noiseImproper loadingUtensils may not be secure or something small may have dropped from the rack. Water may cause utensils to rattle. Make sure everything is securely placed in the dishwasher.
Water left in bottom of dish- washer near filtersDishwashing cycle not completeAllow dishwasher to complete cycle.
Some is normalWater left in removable coarse filter is normal.
Dishwasher will not drainAir Gap Drain hose Filter systemBe sure air gap is not blocked or plugged.

Asko 1805 dishwasher troubleshooting

ProblemResponse
The machine will not start1. You have forgotten to press the main switch or start button.
2. The door is not properly closed.
3. A fuse has blown.
4. The power supply plug is not inserted in its socket.
Water remains In the machine If the machine should overfill with water, the outlet pump will start automatically. If, however, the water does not pump out, the fault may be due to one of these reasons:1. Outlet hose kinked Check that the hose is not kinked or sharply bent.
2. The strainers are blocked. Clean the coarse and fine strainer and the filter.
3. Outlet hose blocked. Check that nothing has blocked the hole where the outlet hose is connected to the sink drain trap. Check, too, that the conical connecting pipe is cut so that the internal diameter is as large as possible, but at least 18 mm.
4. The outlet pump can be blocked.
Poor dishwashing performanceCheck the following points:
1 .That the spray arms are not being prevented from turning by items sticking down from the upper basket and that the holes in the spray arms are not blocket by dirt.
2. That the spray arms can rotate freely, and are not being slowed by grit in the bearings. Spin the arms by hand: if they do not spin freely, lift them off and clean the bearings and mounts.
3. That the machine is admitting sufficient water. Check the inlet hose for kinks or sharp bends. Check that the water pressure is sufficient: 30-1 000 kPa (4-145 PSI).
4. That the correct quantity of detergent has been used: Do not use old or caked detergent. Keep the detergent dry and cool in a closed pack. Remember that it should be bought and used fresh.
5.That the strainer is properly positioned and is clean
6. That you have chosen a enough strong programme.
Grey film on washed ItemsA tendency for a grey film to develop on washed items may be due to lime from hard water. The problem can often be alleviated by using an acidic rinse aid, i.e. one containing citric acid (low pH value, as shown on the rinse aid label). If the dishwasher incorporates a water softener, the grey film may indicate that there is no salt left in the softener. Refill it with salt.

Asko D1796 dishwasher troubleshooting

FaultCauses
POOR WASHING PERFORMANCERotation of spray arms prevented by protruding object. Check also that jets in the spray arms are not clogged
Spray arms slowed down by impurities in the bearings. Spin the arms by hand and if they do not spin freely lift them off and wipe the fittings clean
Insufficient flow of water in the machine. Check the inlet hose for kinks or sharp bends. Water pressure may be too low, compensate by increasing the intake time
Deteriorated detergent. Do not use old or caked detergent. Keep the detergent dry and cool in a closed pack. Remember that detergent is perishable. Avoid large packs
Inferior detergent. Try a different one
Unsuitable dosing of detergent. Ensure that the dose suits hardness of the water
The fine filter is not fitted properly. If it is soiled, clean it
Wash programme is too weak. Change to a more intensive programme and higher temperature
Dishware not arranged properly. Make certain that soiled parts face downwards and inwards
GREY FILM OR MARKS ON WASHED DISHWARETo establish the cause of the grey film make a test using distilled water: Pour on a few drops, rub
thoroughly and dry. Clean? If so, the cause can be one of the following:
• Water level is too low.
• Inadequate drain pumping.
• Glasses and cups have tipped over.
• Salt leaking from the softener. Make certain the lid is tight, otherwise call for service.
• Rinse-aid dispenser incorrectly set.
Possible causes
Not cleaned with distilled water? Test using citric acid: Dissolve 1 tsp citric acid in 1 dl boiling water.
Pour on a few drops, rub thoroughly and dry.
Did citric acid make it clean? If so, the fault can be one of the following:
• Malfunctioning or incorrectly set softener.
• Wrong type of salt. Replace the salt.
• Salt container is empty. Refill
Still not clean after testing with citric acid?
• The cause is probably temperature that is too high and/or too much detergent. This type of film, or etching, cannot be remedied, only prevented. Wash glasses at low temperature and dispense the amount detergent with care, and avoid heated drying. Consult the maker of the detergent
DISHWARE HAS STICKY WHITE/BLUE FILMConcentration of rinse aid is too high. Modify the dose. If the water is very soft it may be suitable to dilute the rinse aid with an equal amount of water
STAINS ON SILVER OR STAINLESS STEELSome remains of food, eg, mustard, mayonnaise, lemon, vinegar, salt or dressing can cause stains on stainless steel if left for too long. Rinse away this type of substance if the machine is not to be run straight away. All types of stainless steel can result in stains on silver if contact is made while being washed
Aluminium can result in marks on other objects if contact is made while being washed
STAINS NOT WASHED OFFDetergent that does not contain chlorine (recommended to protect the environment) may be unable to remove severe stains, eg, lipstick, tea stains
MISCELLANEOUSKnocking sound while the machine is running - spray arms hitting protruding objects.
Rattling noises while the machine is running - dishware not properly arranged.
Dishware is not dried - programme without drying was selected or insufficient dose of rinse aid
DISHWASHER WILL NOT STARTMain switch is OFF
Door not properly closed
Fuse has blown
Power supply plug not plugged in
Water tap not opened
WATER REMAINS IN THE MACHINEThe drain pump will start automatically if the machine takes in too much water. If water is not pumped out, the fault may be due to one of the following reasons
Drain hose is clogged. Make certain that there is nothing blocking the connection of the drain hose to the sink drain trap. Waste can fasten at the end of the connecting pipe. Check also that the tapered connecting pipe is cut so that the inside diameter is as large as possible, but at least 18 mm
Kink in the drain hose. Check the hose to eliminate any kinks or sharp bends
Filters are clogged. Clean the tubular strainer, coarse filter and fine filter
Drain pump is clogged. Clean the pump
Ensure that the black/yellow adapting piece is correctly fitted on the left in the bottom drain by the drain pump

ProblemSolution
Detergent left in compartmentBe careful not to load items so dose to the dispenser that the cover will not open to release the detergent.
The dispenser is not supposed to open when you use the Rinse program.
Your dishwasher detergent should be fresh and stored tightly closed in a cool, dry place. Old or caked detergent should be thrown away because it will not dissolve property and will leave a gritty residue on the dishware.
Wait until you are ready to start the dishwasher to add the detergent.
If you are using the Delay program, make sure the dispenser is dry before adding the detergent.
The detergent compartment only opens in the main wash programs, not the Rinse program.
Dishwasher makes unusual noisesThis usually means that something is not loaded properly. Make sure the dishes are securely in place and that nothing has fallen between the basket tines. Also, place small items in the small items compartment and close the lid.
Dishwasher leaksUse only unscented, granular automatic dishwasher detergent. Using a liquid detergent could cause oversudsing and leakage.
You should always use fresh detergent.
The amount of detergent needed for your dishes depends on the hardness of the water in your area. Contact your local utility company to learn the water hardness in your area
Be careful not to overfill the rinse aid dispenser. Spilled rinse aid could cause oversudsing and lead to overflowing. Wipe away any spills with a damp cloth.
Make sure the dishwasher is level.
Dishwasher runs too longIf the temperature of the water entering your dishwasher is below 120°, the dishwasher runs longer because it heats the water to the proper temperature for the program selected. Raising your water heater setting may help to shorten the cycle times. If this doesn’t resolve the problem, call the ASKO Advisory Center.
Dishwasher does not drain properlyMake sure that the cycle was complete before you opened the dishwasher. If not, allow it to complete and check again.
Some water left in the sump area near the drain is normal.
If the plumbing code in your area requires an air gap, make sure that the air gap isn’t blocked or plugged.
If the unit is connected to a garbage disposer, make sure the disposer is empty.
If water backs up into the sink, check the garbage disposer and trap for blockage.
Check the dishwasher filters and drain area for blockage.
Check for a kink in the drain hose
Dishwasher does not fill properlyMake sure the water supply is turned on
Make sure the dishwasher is turned on and the door is closed securely
Check for crimps in the water feed line
The system is designed to detect an overflow. When it does, it shuts off the inlet valve and circulation pump and turns on the drain pump

ProblemSolution
Poor washing performanceThe dishes may not be loaded properly. Make sure that soiled surfaces are facing downward or toward the center of the dishwasher. Also, make sure that the bowls, pots, etc., are not stacked so closely that water can’t reach the soiled surfaces.
Make sure you are using the appropriate program settings for the dirtiness of your dishes.
An item may be obstructing the spray arm rotation. With the baskets loaded and in place, manually turn the spray arms to make sure they move freely.
Your dishwasher detergent should be fresh and stored tightly closed in a cool, dry place. Old or caked detergent will not dissolve properly. Wait until you are ready to start the dishwasher to add the detergent. If you are using the Delay program, make sure the dispenser is dry before adding the detergent.
Your dishwasher detergent may be inferior. Try a different brand.
Make sure the rinse aid dispenser is filled.
If you have hard water in your area, try adding more detergent and increasing the amount of rinse aid dispensed.
Check that the spray arm jets are not clogged.
Poor drying performanceSelect the Heat Dry option.
If you don’t want to use Heat Dry, you can decrease the drying time by opening the door slightly to let out the warm, humid air.
Make sure the rinse aid dispenser is filled
Make sure you use the proper amount of rinse aid.
Do not overload the dishes and be careful to avoid nesting.
Load items with concave bottoms tilted so as much water as possible will run off.
Unload the bottom basket first to avoid spilling water onto the dishes when unloading the top basket.
Dishes washed in higher water temperatures will dry faster.
Certain plastics may need to be towel dried.
Plastic itemsAlways check the manufacturer’s suggested care instructions before washing plastic in your dishwasher. Even dishwasher-safe items should be loaded in the top basket, away from the heating element.
Some high-acid foods can discolor plastic. You should rinse these items if you do not plan to run the dishwasher right away.
Plastic items dry poorly and may need to be towel dried.
Chipped or Broken DishesLoad glasses between the tines, not straddling them

Always load delicate items in the top basket
Do not overload the dishwasher
Do not jam the glasses together when loading
Stains and discolorationsStains or discoloration on dishes could be caused by a number of things. Listed below are some of the most common causes
Too much iron or manganese in the water can cause yellow or brown marks on your dishes. As a temporary solution, in place of the prewash detergent, use one teaspoon to one tablespoon of citric acid crystals. You should consider installing a water filtering system
Coffee and tea stains usually have to be removed by handwashing in a solution of 1/2 cup bleach and one quart of water. (Do not use on sterling silver or silver plate.) Be sure to rinse these items thoroughly before putting them in the dishwasher so there is no bleach residue on the dishware
EtchingUse less detergent. You may be using too much for the water hardness in your area
Use a good quality dishwasher detergent
Do not overload the machine. Water should circulate freely to ensure adequate rinsing and draining
Fill the rinse aid dispenser (unless you have soft water in your area: in which case you may not need a rinse aid.)
Use a lower water temperature setting
Do not use the Heat Dry option
Do not pre-rinse the dishes; just scrape off large food particles and bones
