F1E1 — Control Module Fault
F1E1 indicates an electronic control module (main control board) fault. Per Whirlpool the potential cause is the control module itself; a stuck relay is one possible failure mode but is not the only one — diagnose the board rather than assuming a specific component.

How to fix it
- Press Cancel/Drain twice to attempt to clear the code, then power-cycle the dishwasher at the breaker for 5 full minutes.
- If F1E1 returns, pull the toe-kick and locate the tech sheet folded behind it.
- Inspect the wiring harness from the control board for pinched, melted, or loose connectors. Reseat any loose plugs.
- Run the service diagnostic from the tech sheet to confirm the stuck-relay fault.
- Replace the electronic control board (located behind the toe-kick on most globally-built models).
- Restore power and run a Normal cycle to verify the code does not return.
Why it happens
Typical signs: F1E1 shown on display · Cycle drains then stops · Dishwasher will not start a new cycle · Possible beeping when error appears
- Failed relay on electronic control board A control relay welded itself closed and will not toggle. Usually requires control board replacement.
- Damaged wire harness to control Pinched or shorted harness can mimic a stuck relay. Inspect connectors at the main board behind the toe-kick.
- Power surge event A brownout or surge can lock a relay until it is power-cycled.
