Our Dishwasher recently started acting up. Upon investigation it appears not to be getting water up to the top rack. Anything on the top rack is left dirty, the bottom rack cleans perfectly. Obviously the water is not reaching up to that top level or rack. The jets look to be clear and unobstructed by debris, but I may be wrong. I have tried cleaning it by cycling a gallon of vinegar with no results. Any Suggestions or help would be greatly appreciated since the thing is relativly new. Thanks

If your chopper is clogged, you need to replace this plus the check valve next to it in the housing. Inspect the chopper, if the white plastic end is badly worn, you also have to replace the main pump impeller, this requires pulling out the dishwasher

ApplianceJunk and richappy,

Thank you for all your help.

I cleaned out the food chopper assembly and everythings fine.

It had some built-up detergent and a few toothpicks (I'll have to talk to the kids about that) stuck in there.

After cleaning, alls better.

Thanks again.

The configuration was not exactly the same as in the photo (different model), but I found the screw that, when removed, revealed the chopper screen and blade. It was full of pieces of plastic baggies, unpopped popcorn seeds, and other seeds. I removed it, cleaned out all of the seeds and plastic pieces, re-assembled it, and now the dishwasher runs like new! Top rack cleans everywhere. Question is: Why did Whirlpool keep this screen a secret? Cleaning this puppy will probably be an annual thing in my house! Thanks ApplianceJunk!!

I took my dishwasher apart and found a piece of hard plastic jammed in the cover over the chopper. Then I pulled the chopper out to clean the screen. It wasn't bad. Now I can't put it back in! Is there a trick to getting this screen back in and getting the blade on the gear properly?
