Mike for Model Number Amana ADB2200AWS 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 Read More... Answered by AppliancePartsPros.com | Tuesday, December 6, 2011
