Our Whirlpool Gold dishwasher Model WDT720PADM2 does not clean dishes after six years of use. I have run the diagnostic, (F7 E1 failure, now reset), tested heating element (it's good), replaced inlet valve, checked water inlet and spray arms for blockage. In any operating mode, the unit gets hot and humid inside, but does not spray water.

I need input before I try to figure out potential pump issues, or ...

Thanks in advance.

Hi, Usually the wash motor(aka circulation motor) that is the culprit.

To verify that, you can use a DMM(Digital Multimeter) to confirm 120 Volts AC at the wash motor when it should be running. This a common problem with this model.

Its actually less expensive to get the complete sump/wash motor assembly, and the diverter comes with it too:
