KitchenAid Dishwasher Error Code F4E3: Meaning and Fix
Reading the dishwasher display
A dishwasher reports its fault in the display window, or by blinking a cycle light a set number of times with a pause between groups. Count the blinks and pauses before opening the door. KitchenAid pairs the number with a letter group in the manual, so match the exact characters.
KitchenAid is Whirlpool Corporation's premium appliance line. Its dishwashers, ranges, microwaves and refrigerators share Whirlpool boards but use their own panel layouts and numbering in the manuals. The codes apply to model numbers such as KUDS24SEWH1, KUDS01DJSS0 and KHMS155LSS4; check the label on your unit to confirm yours.
What causes F4E3
- The heating (or its connector and wiring) has failed or come loose
- High-limit device or thermal fuse has opened
- Igniter is weak or will not glow
- Relay on the control board that powers the heater has failed
- Gas supply or valve is not delivering fuel
- Heating element or burner has burned out or shorted
How to fix it
- Cycle the power: switch off the dishwasher breaker for about a minute (or unplug it if you can reach the cord), restore power and run a short cycle.
- Before opening any panel, switch off the breaker or unplug the appliance; this circuit can carry line voltage.
- Confirm the power supply is correct (both legs of the 240 V circuit on electric units) or that the gas shutoff is open on gas units.
- Inspect the element, igniter or burner for visible blistering, cracks or debris.
- With power disconnected, test the element or igniter for continuity with a multimeter; infinite resistance means it has failed.
- Replace the failed heater, igniter or limit device, then run a short test cycle to verify heat.
- Run a full short cycle or function again and confirm the code stays gone before putting the appliance back into normal use.

Questions
What does F4E3 mean on a KitchenAid dishwasher?
It is a fault code from the KitchenAid control. It indicates a problem with the heating circuit, specifically the heating. A power reset is the first thing to try.
Can I keep using the dishwasher while it shows F4E3?
Stop using it until it has been checked. This fault involves heat, high voltage or sealed-system parts, and running it can damage the appliance or create a safety risk.
Do I need a technician to clear F4E3?
Often yes. Part of this repair means testing live circuits or replacing a control board, so a technician is the safer choice unless you are comfortable with electrical diagnosis.
