How can I tell if my chopper assembly # AP3039186 needs to be changed?
In most cases the white plastic that is on the chopper blade would most likely to have broken causing the blade not to work. If this is broken replace the chopper.
Our dishwasher started making a vibratory loud noise last week, the top rack quit coming clean, so I replaced the water inlet valve and took out the chopper assembly. It was gooped up quite a bit. It seemed to clean better but then quit again and is still loud. I took it apart and the chopper was gummed up again with food. I cleaned it again. Turning the chopper blade will not turn the motor unit but I an manually turn the motor unit and the blade turns. Does the chopper unit need replaced or is the motor going bad? Thanks
Answer Hello Scott,
The chopper has to be bad since the food is stopping up the screen. This is a common failure but the fix will correct the issue until something hard gets into the chopper area again. I do recommend to use a wet-vac to suck out the water and whatever debris is down in this chamber. The reason I have made this a habit is because many times there will be a small, clear piece of broken glass in the chamber and since you cannot see it, it will break the new part and make you have to execute the repair all over again.
