I have a Quiet Partner II Dishwasher. It still seems to fill with water (and drain after selecting the Cancel/Drain button), but will not wash. It sounds like the motor is getting power (you can hear the humming as the wash cycle begins - but no wash). I checked the chopper, cleaned some debris wrapped up in it, but washer still does not work. I'm guessing the motor and/or pump is bad? ANy other possibilities?

Thanks, Leif
