KitchenAid Dishwasher F4 E3 Error Code

KitchenAid identifies F4 E3 as a heating error and recommends a control power cycle. If the code returns, the manufacturer directs the owner to service rather than internal heater or live-electrical testing.

Applies to KitchenAid dishwasher using the documented F/E or H2O display family

What the appliance detected

Detected condition

The dishwasher control detected a heating error condition.

What may contribute

Possible causes

  • The control detected that the expected heating behavior was not achieved.
  • A transient control condition may clear after one documented power cycle.
  • Persistent heater, sensor, wiring, relay, control, or water-circulation issues 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 cycle context

    • Photograph F4 E3 and record the full model number.
    • Note whether the dishwasher had been washing, drying, or sanitizing when the code appeared.

  2. Power-cycle the control once

    • Disconnect dishwasher power for 30 seconds using the normal plug or dedicated breaker, then restore it.
    • Run one normal cycle only if there is no burning odor, smoke, leaking, or breaker problem.

  3. Request service if the heating code returns

    • If F4 E3 returns, stop repeated resets.
    • Internal heater, sensor, wiring, relay, pump, or control checks are service-level work.

Actions not recommended

  • Do not access the heater circuit, wiring, relays, pump, or control board.
  • Do not probe live voltage or defeat the door interlock.
  • Do not replace a heating element from F4 E3 alone.

When to stop and request service

  • F4 E3 returns after one documented power cycle.
  • There is a burning odor, smoke, repeated breaker trip, or obvious overheating.
  • Internal heater, sensor, wiring, pump, relay, or control diagnosis is needed.
