F4E3 is a heating error in KitchenAid's owner help. A 30-second power cycle is the step, with service if the code returns.
Model compatibility: KitchenAid reuses codes across series and model years, so F4E3 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
What this code means
F4E3 is listed by KitchenAid as a heating error.
KitchenAid’s owner help gives F4E3 one line: “Potential Cause: Heating Error.” The neighbouring code F4E2 reads “Heating System” and both pages carry the same instructions. No part and no temperature are named, and the dishwasher’s behaviour while the code is up is not described.
At a glance
| Code | F4E3 |
|---|---|
| What it means | F4E3 is a heating error on the dishwasher. |
| What you can check | Unplug the dishwasher, or switch its breaker off if hard wired, wait 30 seconds, then restore power. Keep your hands out of the tub and door area, where parts may be hot. |
| When to call a technician | If F4E3 returns after the reset, schedule service. Mention whether the dishwasher plugs in or is wired directly. |
Doing the 30-second reset
- Plugged-in dishwasher: unplug it and wait.
- Hard-wired dishwasher: switch the breaker off at the house electrical panel and wait.
- After 30 seconds, plug it in again or switch the breaker back on.
- If F4E3 returns, KitchenAid says to schedule service.
When to stop
The page asks for service when the code is back after the reset. A code that outlasts a correct 30-second cycle leaves only the heating system itself, and checking it involves live electrical parts. A technician has the equipment for that. In the meantime, keep your hands out of the tub and door area right after a heat code, because water and parts there may be hot.

F4E4 also appears in KitchenAid’s service documents; it concerns the wash motor, not the heater.
FAQ
Does F4E3 rank above F4E2?
No ranking is given. Each carries a single potential cause and the same reset.
Is the breaker for plug-in dishwashers too?
The help page treats them apart: unplug for plug-in, breaker for hard wired.
