My dishwasher does not clean well it 4 years old.
Answer Hello John. Based on the information you provided, you will need to check the water level inside the unit and make sure it is filling up to the bottom of the heater assembly. If not, then the water valve 6-920534 could be bad on the unit. If the water level is good, try cleaning the filters under the spray arms inside the unit with dishwasher magic TJ104. Hope this helps.
Glasses and cups in the upper rack had food particles inside after a wash cycle. I removed the filter but could not find a way to clean it. The replacement part diagram shows a single pump filter plate (part # AP4362441) and apparently no way to take it apart for cleaning. If there is not a way to clean the filter, how often should it be replaced? My dishwasher is 5 years old and the filter was completely clogged. Thanks for the information.
Answer Mike, You normally don't need to clean or replace the filter flow plate, unless there is a heavy detergent or hard water deposit built up on the filter screens, at which point, you need to remove the lower spray arm, upper filter plate, pressure dome and impeller. It's a lot easier to make sure your water temperature is hot enough to disolve the detergent properly (120 dgrs in the bottom of the tub at the first fill of the cycle)You also want to run a citric acid based cleaner, such as "Glisten" WX10X10205 through the dishwasher, a couple of times a year, to reduce any debris or build up from the chemicals. Good Luck and Thanks
