KitchenAid Dishwasher F3 E2 Error Code

KitchenAid identifies F3 E2 with the thermistor or OWI sensor. The manufacturer directs owners to power-cycle the control once and schedule service if the code returns rather than meter or replace the sensor from the code alone.

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

What the appliance detected

Detected condition

The dishwasher reports a thermistor or OWI sensor fault condition.

What may contribute

Possible causes

  • The control detected an abnormal condition associated with the thermistor or OWI sensing system.
  • A temporary control state may clear after one documented reset.
  • A persistent sensor, connector, harness, or control issue may require service.

Start conservatively

Safe preliminary checks

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

  1. Record the code and model

    • Photograph F3 E2 and record the complete model number.
    • Note whether the issue appeared during washing, heating, or drying.

  2. Power-cycle once

    • Disconnect dishwasher power for 30 seconds using the normal plug or breaker, then restore it.
    • Run one normal cycle only if the appliance is otherwise safe to operate.

  3. Stop if F3 E2 returns

    • If the code returns, request service instead of repeatedly resetting the dishwasher.
    • Sensor and wiring diagnosis requires internal access.

Actions not recommended

  • Do not remove panels to access the thermistor, OWI sensor, sump, wiring, or control.
  • Do not perform resistance or live-voltage tests as an owner check.
  • Do not replace the sensor from F3 E2 alone.

When to stop and request service

  • F3 E2 returns after one documented power cycle.
  • The dishwasher also shows abnormal heating, washing, or repeated cycle interruptions.
  • Internal sensing, connector, harness, or control diagnosis is needed.
