Dishwasher Troubleshooting, the Problem Solver


1. Problem
Dishwasher won`t run
Possible cause and remedy
A fuse in your home may be blown, or the circuit breaker tripped. Replace fuse or reset circuit breaker. Remove any other appliances from the circuit.
2. Problem 
Unusual noise
Possible cause and remedy
Utensils may not be secure on rack pins, or something small may have dropped from the rack. Water is causing utensils to rattle. Make sure everything is securely placed in dishwasher.
3. Problem 
Dishes don`t dry
Possible cause and remedy
Make sure inlet temperature is correct. Unload the bottom rack first. Water from dishes in the top rack may be spilling into the bottom rack. Check for improper loading. Dishes shouldn`t nest together. Avoid overloading. Check the rinse agent dispenser to see that it`s not empty.
4. Problem
Unclean dishes and flatware
Possible cause and remedy
Check inlet water temperature. It should be at least 49C (120F). Water pressure may be temporarily low. Turn on a faucet. Is water coming out slower than usual? If so, wait until pressure is normal before using your dishwasher. Improper rack loading.
5. Problem
Black or grey marks on dishes
Possible cause and remedy
Aluminum deposits often leave marks when they rub against other things. Remove marks with a mild abrasive cleanser.
6. Problem
Detergent left in dispenser cups
Possible cause and remedy
Water may not be teaching the detergent cups. Move dishes that may be blocking detergent cup. The dispenser cover may not be opening or may be blocked by improperly loaded items. If you used a powder detergent, open the cup and remove any caked-on detergent. If the cup still doesn`t open automatically, call for service. Detergent may be old. If the powder detergent is hard or caked in the box, throw it away. The detergent may not be working well. Try another brand.
7. Problem
Yellow or brown film
Possible cause and remedy
Tea or coffee can stain cups. Remove the stain by hand, using a solution of ½ cup bleach and 3 cups warm water. An overall yellow or brown film on dishes or glassware can be caused by iron deposits in water. A special filter in the water supply line is the only way to correct this problem. Your water softener company can tell you about the filter. Yellow film on sterling silver results when wash copper utensils in the same load. Silver polish will usually remove this stain.
8. Problem
Spots and filming on glasses and flatware
Possible cause and remedy
Spotting can be caused by all these things:
– extremely hard water
– low inlet water temperature
– overloading the dishwasher
– improper loading
– old or damp power detergent
– phosphate level in detergent too low
– rinse agent dispenser empty
– too little detergent
Local water conditions and personal preferences vary. Try several brands of detergents to find one that gives the best results for you. A liquid dishwashing detergent may help reduce filming.
To remove stubborn spots and film from glassware:
– remove all metal utensils from the dishwasher
– do not add detergent
– select HEAVY SOIL cycle
– start the dishwasher and allow to run for 18 to 22 minutes. The dishwasher will now be in the main wash
– then open the door and pour 500ml (2 cups) of white vinegar into the bottom of the dishwasher 
– close the door and allow to complete the cycle
If vinegar rinse doesn`t work: repeat as above, except use ¼ cup (60ml) of citric acid crystals instead of vinegar. (Most drugstores carry citric acid crystals). 
Using a vinegar or citric acid crystal rinse more than twice a month? Consider a home water softener
9. Problem
Cloudiness on glassware
Possible cause and remedy
If vinegar or citric acid crystal rinse doesn`t work, the cloudiness is “etching”. The film cannot be removed. 
It can be prevented: use less detergent if you have soft water. Wash glassware in the shortest cycle that will get them clean. Water temperature entering dishwasher exceeds 63 C (150 F)
10. Problem
Chipping of China
Possible cause and remedy
Rough handling can cause chipping. Load with care. Make sure glassware and china are secure and can`t jar loose. Make sure tall glasses and stemware will clear the top the tub when you push the rack into the dishwasher. Always use the top rack for delicate items. 
Use CHINA-CRYSTAL cycle for fine China
11. Problem
Small amount of water standing in the bottom of the tub
Possible cause and remedy
Water around the outlet on the tub bottom at the back of the tub is normal. It is clean water. It`s there to keep the water seal lubricated.
12. Problem
Water won`t pump out of the tub
Possible cause and remedy
If the entire bottom of the tub has water, you may have a drain problem. Clean the air gap, if you have one.
Check the kitchen sink. Is it draining well? You may need a plumber. If dishwasher drains into disposer, run disposer to clear. Be disposer is not clogged
13. Problem
Suds in the tub
Possible cause and remedy
Sudsing detergents are not meant for dishwashers. USE ONLY AUTOMATIC DISHWASHER DETERGENTS TO AVOID SUDSING. 
To remove suds from the tub: open the dishwasher. Let suds evaporate. Add 1 gallon (4 litres) of cold water to the tub. Close and latch the dishwasher. Pump out water by slowly turning the control dial until a drain period is reached.
14. Problem
Dishwasher leaks - Fiood Buzz The simple water leak alarm that warns you of a water problem before it becomes a flood. Possible cause and remedy
Suds can cause unit to overflow. That`s why it`s so important to use a detergent that`s designed for automatic dishwashers.
Spilling the rinse agent can cause foam during washing. This can lead to overflowing. Wipe up accidental spill of rinse agent with a damp cloth.
