F4E3 — Heating Error
Whirlpool's OEM documentation lists F4E3 as a heating error. Whirlpool's own fix guidance is to power-cycle the dishwasher (unplug it or reset the breaker for a minute) and restart a cycle; if F4E3 returns, the unit needs service. Note: on an older generation of Whirlpool/Global HE service documentation, this same code was assigned to a circulation-pump communication fault instead — if your model is from that older platform and the heating circuit checks out fine, also check the circulation pump wiring.

How to fix it
- Power off at the breaker (or unplug) for a minute, then restore power and restart a cycle — this is Whirlpool's first recommended step.
- If F4E3 returns, power off again and check the wiring harness to the heating element and water-temperature sensor for looseness, corrosion, or burn marks.
- With power off, test the heating element for continuity; replace it if open.
- If the element and wiring test good but F4E3 persists, the control board likely needs replacement.
- On older Whirlpool/Global HE platforms, if the heating circuit tests fine, also inspect the circulation pump harness — some service documentation for that generation ties F4E3 to a pump communication fault.
Why it happens
Typical signs: F4E3 on display · Cycle stops or won't complete · Dishes come out with detergent film or not fully dried · Code returns after a power cycle
- Failed or open heating element The element can't reach or hold the temperature the cycle calls for.
- Faulty water-temperature sensor or thermostat A bad reading in the heating circuit can trip the error even if the element itself is fine.
- Damaged wiring to the heating circuit A loose or burnt connector between the control and the heater interrupts the circuit.
- Control board fault Less common — only after the heating element, sensor, and wiring test good.
