Top rack won't clean - Kenmore 24 in. 15932 Built-in Dishwasher

Hi


Thanks for using FixYa. First of all please check the Water temperature by using a thermometer inside the dishwasher to measure the water temp. It should be as close to 125 degree F to 140 degree F as possible. Now try using the temperature boost feature if your dishwasher is equipped with this cycle feature and check if this will help your wash ability issues.

Now check the Powder soap by making sure that you store your soap in a dry environment and it is not stale and clumping together. Possibly try a different detergent like a liquid or gel. Also, make sure the dishes are loaded properly, or dishwasher is not overloaded.

To check the proper filling dishwasher will fill with water up to and around the heating element. If water is more below the heating element, you may have low water pressure or a problem with the fill valve. Try & listen if it sounds like it is spraying the water around with enough pressure.
For low water pressure, try to clean the screen at the entrance of the fill valve, sometimes the fill valve can fail and not allow the proper water into the dishwasher and may need to be replaced. And, check the spray arm and pump cover for splits or leaks

Low water fills are a very common trouble maker with today's dishwasher.

Please do rate this solution and revert for further assistance.

Thanks

Make sure the top rack spray arm moves freely. Check that there is no debris stop water flow inside the spray arm. When you load dishes make sure no dishes stop the spray arm movement. Check the pressure hole where the arm inlet slides into. Make sure if there is another pressure hole that the check valve flap is not stuck open. The water pump in your system might have low pressure due to a plugged filter screen. If your dishwasher does not have a self-cleaning screen you may need to clean it. If it is clear then the pump might need replacement.
