Wash motor fault

At the wash step, listen closely: a hum with no spray means the premium wash motor is energized but the impeller or diverter is bound
On these KDTM units, pull the sump apart and inspect the diverter disc, where fine food particles wedge and stall the assembly
Sweep the sump for a sliver of broken stemware — a cracked wine glass is the classic KitchenAid seizure
Bench-test the motor capacitor; a weak capacitor leaves the motor humming without enough torque to start
Only then check the board relay for its wash-phase click before condemning the costly motor
Pro Diagnostic Tip
F7E1 on a KitchenAid KDTM dishwasher means the wash motor was commanded but did not turn, and on this premium platform the diverter disc that steers water between the upper and lower arms is the part most likely to jam — fine food particles pack around it and stall the whole assembly. Disassemble and clean the sump, and look hard for broken stemware glass, before spending on the motor. A dead-silent motor rather than a humming one shifts the fault to the capacitor or the board relay.
