Drain pump failure

Remove lower spray arm and filter assembly
Clear any debris from the sump area — glass shards, food labels, bones
Check drain hose for kinks at the disposal or air gap connection
If sump is clear and pump still not working, the pump motor has failed
Pro Diagnostic Tip
On a freshly-installed Whirlpool-built 665-series Kenmore, the classic phantom drain failure is a garbage-disposal knockout plug left in place — the installer must punch it out or the dishwasher has nowhere to pump. Confirm that slug is gone before you ever open up the drain pump.
