Though F1E2 is a "Motor Control Unit Error"... my issue was NOT the MCU/motor, but the faulty pump (W10730972) found here...

I racked my brain and pocketbook over this misleading code... after 2 MCUs, 2 CCUs, and 1 MOTOR later, only the new DRAIN PUMP fixed it. Imagine that?
Hopefully that's your issue; otherwise, it might get expensive trying to chase down the problem! My model # is MHWE200XW00.
