Drain pump fault

Cut power, pull the lower rack and filter, and reach the drain pump in the sump of the Whirlpool dishwasher
Clear glass shards, seeds, or a label from the impeller chamber that can stall or short the pump
Read the drain pump winding resistance and treat an open or dead-short value as a failed pump motor rather than a clog
If the pump tests good, inspect its harness and the control pump-driver output for a scorched connector before condemning the board
Pro Diagnostic Tip
This fault is the drain pump drawing an electrical fault, a step beyond the F8E1 slow-drain restriction: here the pump motor itself has shorted or seized rather than the hose being blocked. Clear the impeller and ohm the winding before ordering the pump, since a single glass sliver can stall it and mimic a dead motor.
