How to Troubleshoot a Kenmore Dishwasher 665?
When experiencing problems with a Kenmore Dishwasher 665, troubleshoot by checking first for the most common problems, moving down to less common problems until the cause of the trouble is identified. Poor wash quality, the most common problem reported by Kenmore owners, can be due to anything from low water temperature to improper loading technique.
-
Check the wash and rinse water temperature
The dishwasher should use water at about 150 degrees Fahrenheit for both its wash and rinse cycles. To check the water temperature, place a candy thermometer in an upturned glass during a rinse cycle.
-
Look for blockage in the air gap
The air gap, which prevents water from the sink drain from leaking into the dishwasher, can trap chunks of food and prevent proper drainage of dish water.
-
Check for clogs in the water system
Check both the pump suction screen and the spray arms for emulsified hard water, bits of food or glass shards that can contribute to water blockage.
-
Switch detergents
Acidic or hard detergents can damage the dishwasher and dishes. See if switching to a different detergent alleviates the problem.
-
Load dishes properly
Loading dishes improperly can contribute to poor washing. Check the owner’s manual for instructions on how to properly load the dishwasher.
