Kitchenaid dishwasher troubleshooting

Your dishwasher makes strange noises, the water does not come or you might have noticed the leakage – the first question you ask is whether it is necessary to call the service center or you can repair it yourself. First of all, it is necessary to understand the cause of a malfunction, since the reason might hide in the fact that there is simply no water in the house or the central filter of the machine is clogged.

PROBLEM CAUSESOLUTION
Food Soil Left On DishesSlowdown of wash arm due to high sudsUse recommended dishwasher detergents only. Never use soap or laundry detergents. Add more dishwasher detergent to increase amount of sudsinhibitors.
Improper loadingFollow loading instructions in dishwasher
Low water pressure due to insufficient fillHome water pressure should be 20 to 120 psi for proper dishwasher fill. A booster pump on the water supply may be necessary if pressure is too low.
Use of incorrect, too little or ineffective detergent.Use recommended dishwasher detergents only. Follow recommendations for amounts; never use less than one tablespoon per load. Detergent must be fresh to be effective. Always store it in a cool, dry area, preferably in an airtight container.
Detergent cakes in dispenserUse fresh detergent only. Do not allow detergent to sit for several hours in a wet dispenser. Have dispenser checked to make sure it is working properly.
Water temperature is too lowTurn home water heater up so water entering dishwasher is 140F (60DC) minimum.
Filter cleaning spray nozzle on wash arm is blockedRemove lower wash arm and turn upside down. Check single spray nozzle (hole) located on underside of wash arm. It cleans the filter. If nozzle is blocked, clean out with a toothpick.
Spotting and FilmingHard water or high mineral content in waterConditioning the final rinse water with a liquid rinse agent helps eliminate spotting and filming. The Automatic Rinse Agent Dispenser can be installed as an optional accessory. Keep rinse agent, like Jet Dry, in the dispenser at all times.
A packaged non-precipitating water conditioner can be mixed with detergent to minimize hard water problems.
Water temperature is too lowTurn home water heater up so water entering dish- washer is 140F (60rC) minimum.
Use of incorrect detergentsUse recommended dishwasher detergents only.
Incorrect amount of detergent Use of ineffective detergentsFollow recommendations for amount. Heavy soil and/or hard water generally require extra detergent.
Detergent should be fresh. Store in a cool, dry place, preferably in an airtight container. Discard lumpy detergent.
Insufficient fill caused by low water pressureHome water pressure should be 20 to 120 psi for proper dishwasher fill. A booster pump on the water supply may be necessary if pressure is too low.
Silica Film or Etching (Silica Film is a White Iridescent Deposit; Etching is a Cloudy Film)A water chemical reaction with certain types of glassware. Usually caused by some combination of soft or softened water, alkaline washing solutions, insufficient rinsing, over- loading the dishwasher, and heat of drying.It may not be possible to prevent problem, except by hand washing. To retard this process, use a minimum amount of detergent but not less than one tablespoon per load. Use a liquid rinse agent and underload the dishwasher to allow thorough rinsing. Remove glasses from dishwasher before dry cycle. Silica Film and Etching are permanent and cannot be removed.
Pitting of Stainless Steel Flatware Tarnish on Silver or SilverplateProlonged contact with foods containing salt, vinegar, milk products or fruit juices.Use Rinse & Hold Cycle if flatware is not washed immediately after use.
Prolonged contact with food soils containing sulfide—eggs, mayonnaise and seafoodUse Rinse & Hold Cycle if silver or silver plate are not washed immediately after use. Hand buff silverware occasionally.
Bronze tarnish is exposed base metal where silver has worn away on silverplate. Base metal reacts with detergents and heat to give tarnish effect.Soak in vinegar for 10 minutes to remove tarnish.
For permanent protection, have flatware replated.
Darkening of Aluminum WareMinerals in the water or undiluted detergentAlways use automatic dishwasher detergents as they contain ingredients to protect aluminum. Ware should not be placed where it can be sprinkled with undiluted detergent. Remove at end of final rinse and towel dry. Do not stack to dry.
Black or Gray Marks on DishesAluminum markingsAluminum pieces should be loaded so that they will not rub against dinnerware during washing. Throw- away aluminum items should not be dishwasher washed because they may break down and cause marking. Aluminum markings can be removed by using a mild abrasive cleanser.
Brown Stains on Dinnerware and Dishwasher InteriorHigh iron content in water supplyRemove by washing dishes (after food soil has been removed) with 1 teaspoon to 1 tablespoon of citric acid crystals added to Main Wash compartment of detergent dispenser. Do not use detergent. Follow with a Low Energy Wash Cycle with detergent. If treatment is needed more often than every other month, the installation of an iron removal unit is recommended.
White Spots on Cookware with Non-Stick FinishSeasoning removed by dishwasher detergentsReseason cookware after dishwasher washing.
Cycle Takes Extremely Long TimeWater temperature is too lowTurn home water heater up so water entering dish- washer is 140F (60C) minimum.
White Spots on Cookware with Non-Stick FinishSeasoning removed by dishwasher detergentsRe-season cookware after dishwasher washing.
Cycle Takes Extremely Long TimeWater temperature is too lowTurn home water heater up so water entering dishwasher is 140F (60C) minimum.
Dishes Do Not Dry CompletelyDishes do not drain properly Dishes must have proper water drainage. Do not overload. Follow instructions for loading in dish- washer Use and Care Guide. Use a rinse agent to speed draining.
Some plastics, due to material, may need to be towel dried.
Fading of Patterns on ChinaHigh water temperature and strong detergentBefore washing china in the dishwasher, check manufacturer’s instructions to see if china is dishwasher safe. Or test wash a piece for about a month by leaving it in the dishwasher to see if and when fading occurs. Do not wash antique painted china in dishwasher.
Warped or Cracked Wooden WareHigh water temperatureWooden ware should not be dishwasher washed.
Rust on Cast IronHot water and detergents remove protective seasoningCast iron should not be dishwasher washed. To reseason utensil, coat with unsalted fat and heat in a slow oven for one to two hours.
Plastic Containers Warp or Lose ShapeHigh water temperatureCheck care instructions for plastics to determine if they are dishwasher safe, heat resistant.
Odor in the DishwasherDishes only washed every two to three daysRun a Rinse & Hold Cycle at least once or twice a day until a full load is accumulated.
Chipping of DishwareImproper loadingLoad dishes and glasses so that they are stable and do not strike together from washing action. (Note: Some types of china and glassware are too delicate for automatic dishwashing and should be hand washed: for example: antiques, featheredged and similar types.) Moving racks in and out smoothly will also minimize chipping
Fine Filter Needs Frequent CleaningFilter is not placed in dishwasher correctlyMake sure fine filter is seated properly under wash arm.
Spray nozzle on wash arm is blockedRemove lower wash arm and turn upside down. On under side of each tube is an indentation. In one of these indentations is a nozzle (hole) which cleans filter. If this nozzle is blocked, clean out with toothpick.
Dishes not scraped before loadingMake sure leftover food, bones, toothpicks and other hard items are scraped from dinnerware before loading.

PROBLEMSOLUTION
Dishwasher does not runNOTE: It is normal for the dishwasher to repeatedly pause several times during a cycle.
If the Start/Resume light is blinking, close the door and push START/RESUME.
Be sure the door is closed and latched.
Check that there is not an interference with large casserole dishes and the wash system at the back of the dishwasher. Adjust loading as necessary to ensure door is closed and latched.
Be sure you have selected a cycle.
Be sure there is power to the dishwasher. A circuit breaker or fuse may have tripped.
If lights other than Start/Resume blink and the unit will not run, you will need to call for service.
Detergent remains in the dispenser or tablet is on bottom of tubCheck for dishware such as cookie sheets, cutting boards, or large containers, etc., that may be blocking the detergent dispenser from opening properly.
Be sure your detergent is fresh and lump free.
Be sure the cycle has completed (the Clean light is on). If it has not completed, you will need to resume the cycle by closing the door and pressing START/RESUME.
Cycle runs too longTo use less water and reduce energy consumption you will encounter cycles that typically run for up to 3 hours.
A water heater setting of 120°F (49°C) is best, the dishwasher will delay longer while heating cooler water.
Some options will add time to the cycle. The Heat Dry option adds approximately % hour.
Try the 1 Hour Wash cycle.
Run the hot water at a faucet close to the dishwasher before starting the cycle.
Dishwasher not dryingNOTE: Plastic and items with nonstick surfaces are difficult to dry because they have a porous surface which tends to collect water droplets. Towel drying may be necessary.
Use of rinse aid along with the Heat Dry option is needed for proper drying.
Proper loading of items can affect drying. Glasses and cups with concave bottoms hold water. This water may spill onto other items when unloading.
Unload the bottom rack first.
Locate these items on the more slanted side of the rack for improved results.
Will not fillBe sure the water is turned on to the dishwasher.
Check that the float is free from obstructions.
Check for suds in the dishwasher. If foam or suds are detected, the dishwasher may not operate properly or may not fill with water.
Water remains in the tub/will not drainBe sure the cycle has completed (the Clean light is on). If it has not, you will need to resume the cycle by closing the door and pressing START/RESUME.
If dishwasher is connected to a food waste disposer, be sure the knockout plug has been removed from the disposer inlet.
Check for kinks in the drain hose.
Check for food obstructions in the drain or disposer.
Check your house fuse or circuit breaker.
Hard water (white residue on dishwasher interior or glassware)NOTE: Extremely hard water mineral deposits can cause damage to your dishwasher and make it difficult to achieve good cleaning. A water softener is strongly recommended if your hardness is 15 grains or more. If a water softener is not installed, the following steps may help:
Use a commercial cleaner designed for dishwashers once per month.
Always use a rinse aid.
Always use a high-quality, fresh detergent.
Use a detergent booster/water softener additive designed for dishwashers.
OdorsNOTE: If the dishwasher is not used daily, you can run a rinse cycle with the partial load daily until a full load is ready to run, or use the Top Rack Only option (on some models) for partial loads.
Run a vinegar rinse through the dishwasher by putting 2 cups (500 mL) of white vinegar in an upright glass measuring cup in the lower rack. Run a normal cycle with the Heat Dry option turned off. Do not use detergent.
The dishwasher may not be draining properly.
NoisySurging sounds can occur periodically throughout the cycle while the dishwasher is draining.
Normal water valve hissing may be heard periodically.
A normal snap sound may be heard when the detergent dispenser opens during the cycle and when the door is opened at the end of the cycle.
Improper installation will affect noise levels.
A thumping sound may be heard if items extend beyond the racks and interfere with the wash arms. Readjust the dishware and resume the cycle.
Food soils remain on dishesBe sure the dishwasher is loaded correctly. Improper loading can greatly decrease the washing performance.
Select the proper cycle and option for the type of soils. The Heavy Duty cycle with the ProScrub (on some models) option can be used for tougher loads.
Be sure the incoming water temperature is at least 120F (49C).
Use the proper amount of fresh detergent. More detergent is needed for heavier-soiled loads and hard water conditions.
Scrape food from dishes prior to loading (do not prerinse).
Dishes dirty/suds in dishwasher/cycle not completeIf foam or suds are detected by the dishwasher sensing system, the dishwasher may not operate properly or may not fill with water.
Suds can come from:
Using the incorrect type of detergent, such as dish detergent for hand washing dishes, laundry detergent, or hand soap.
Not replacing the rinse aid dispenser cap after filling (or refilling) the rinse aid.
Using an excessive amount of dishwasher detergent.
Call for service.
If no water was present in the machine at any time during a heated wash cycle, the cycle will end and the Clean LED will not come on.
Did not sanitizeIf the sanitized light is blinking, the load is NOT sanitized. The cycle was interrupted in the final rinse, or the temperature for your water heater is set too low. Set your water heater to 120F (49C).
Damage to dishwareImproper loading can cause dishes to become chipped or damaged.
Blinking lightscase, the Start/Resume button LED, the Cycle Status Indicator LED(s), and the countdown bars on the Cycle Status Display all blink together to indicate that attention is needed.
Blinking LED's can also occur when certain errors have been detected. In this case,the Clean/ Complete LED will blink one time with a pause in between blinks.
Call for service.
Cloudy or spotted dishware (and hard water solution)Liquid rinse aid is necessary for drying and to reduce spotting.
Use the correct amount of detergent.
Confirm that the cloudiness is removable by soaking the item in white vinegar for 5 minutes. If the cloudiness disappears, it is due to hard water. Adjust the amount of detergent and rinse aid. If it does not come clear, it is due to etching.
Be sure the incoming water temperature is set at 120F (49C).
Try using the High Temp and Sani Rinse options.
To remove spotting, run a vinegar rinse through the dishwasher.
Wash and rinse the affected dishware and load into dishwasher. Remove all silverware and metal items. Put 2 cups (500 mL) of white vinegar in a glass measuring cup in the lower rack. Run a normal cycle with the Heat Dry option turned off. No detergent is needed.
Etching (permanent cloudiness)This is an erosion of the surface of the glassware and can be caused by a combination of: water that is too hot, from using too much detergent with soft water or by pre-washing. Detergent needs food soil to act upon. If etching has occurred, the glassware is permanently damaged. To avoid further etching, adjust the detergent amount to match the water hardness, stop pre-washing, and use water heating options only when incoming water temperature is below 120F (49C).
Leaking waterBe sure dishwasher has been installed properly and is level.
Suds can cause the dishwasher to overflow. Measure the detergent accurately and use only detergents designed for use in a dishwasher. Less detergent is needed in soft water. Try another brand of detergent if sudsing continues.
To avoid rinse aid leaking from the dispenser, be sure the lid is securely attached and avoid overfilling.
Tub is discoloredHigh iron content in the water can discolor the tub.
Tomato-based foods can discolor the tub or dishware. A citrus-based cleaner can be used to clean.
