I'd like to follow your advice and check the impeller assy - part # 6-915435 on my Maytag WU494. But, I can't lift the plastic disk above it. It will rotate, but not lift. Is there something else I need to do? Thanks.
There should be a screw in the center of the plastic disk that you would need to remove. You will have to find a way to hold the disc to keep it from turning when removing the screw. Once the screw is out it should just lift out.
Filter AP4112901 is getting cloged up a white materail, this has happen now three times in the last year, never been a problem before. Using SAMS Member Mark dishwasher gel
Answer Hello Bob. It sounds like the gel is clogging the filter 99001791. Make sure the water is turned on and is getting hot at the sink before, you start the dishwasher. This will help break the gel down inside the unit. Hope this helps.
My Maytag dishwasher is not cleaning very well lately. Could this be the filter? If so, will this AP4112901 filter fit?
Answer Hi Pat. This is the filter screen that is right below the top filter hsg. You will do yourself a large favor by using a shop vac, towels and pick tools to clean the entire unit. Remove the racks and the wash arms. Use a pick tool to flush out the wash arms under the sink. Get all the debris out from jet holes. Then you will need to remove all sump hsg screws aside one by one with all the parts so you can reassemble them correctly. The filter screen will be clogged. Going further down into the unit then you will remove the staggered thin washers and get into the rinse arm assy. Expect this to be clogged altogether. You will need to use the pick tools to remove all the debris out from the side vertical slots. 3 more parts from this is the impeller assy. that will need to be checked for clogged or broken vanes. This is part # 6-915435 . Below this is the chopper blade assy. part # 912310. This may be chewed up and need to be replaced. Thank You.
