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

  1. Press Cancel/Drain twice to attempt to clear the code, then power-cycle the dishwasher at the breaker for 5 full minutes.
  2. If F1E1 returns, pull the toe-kick and locate the tech sheet folded behind it.
  3. Inspect the wiring harness from the control board for pinched, melted, or loose connectors. Reseat any loose plugs.
  4. Run the service diagnostic from the tech sheet to confirm the stuck-relay fault.
  5. Replace the electronic control board (located behind the toe-kick on most globally-built models).
  6. Restore power and run a Normal cycle to verify the code does not return.
