I have an Amana washer that was doing a terrible job, I cleaned every removable part, etc. Same thing it was splattering food everywhere. Then we remodeled the kitchen, and put the exact same dishwasher back in 2 months later (it's hooked up to a new garbage disposal). For some reason it works just fine now, we can't explain it. Maybe exhaust pipe was clogged? Maybe it wasn't level? Maybe something wasn't connected right? I guess I'm suggesting removing it entirely and looking for problems?
