KitchenAid Dishwasher F1 E2 / F2 E2 Error Code

KitchenAid documents both F1 E2 and F2 E2 as main-control communication errors with the same owner response: cycle power once, then schedule service if the code returns. They share one canonical guide to avoid duplicate search intent.

Applies to KitchenAid dishwasher using the documented F/E display family

What the appliance detected

Detected condition

The dishwasher reports a main-control communication error on a supported model.

What may contribute

Possible causes

  • A temporary communication state may have interrupted normal control operation.
  • The main control may not be communicating normally with another electronic module.
  • Persistent connector, harness, interface, or control problems require service-level diagnosis.

Start conservatively

Safe preliminary checks

Work in order and stop whenever a step is not supported by the documentation for your model.

  1. Confirm which communication code appeared

    • Photograph the exact F1 E2 or F2 E2 display and record the complete model number.
    • Do not assume the same code meaning applies to a different KitchenAid model without checking its documentation.

  2. Perform one documented power cycle

    • Disconnect dishwasher power for 30 seconds using the normal plug or dedicated breaker.
    • Restore power and test one normal cycle if there are no electrical or water-safety concerns.

  3. Request service if communication fails again

    • If F1 E2 or F2 E2 returns, stop repeating resets.
    • Record any accompanying display, button, or cycle symptoms for service.

Actions not recommended

  • Do not open electronic-control compartments or disconnect internal harnesses.
  • Do not bypass the door interlock or perform live electrical testing.
  • Do not replace a main control, interface, or harness from the code alone.

When to stop and request service

  • F1 E2 or F2 E2 returns after one 30-second power cycle.
  • Controls are blank, frozen, or erratic after power is restored.
  • Internal communication wiring or control diagnosis is required.
