Whirlpool 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. Whirlpool-family codes are usually read as a letter and number pair, with an E sub-code after it.
Whirlpool is the parent platform for Maytag, KitchenAid and Amana, so many of its control boards and fault codes reappear across those brands. Its panels typically report two-part codes such as F5 E2 or flash sequences on the keypad. The codes apply to model numbers such as GU980SCGB2, GU980SCGQ2 and GEW9200LW0; check the label on your unit to confirm yours.
What causes F4E3
- The heating (or its connector and wiring) has failed or come loose
- Gas supply or valve is not delivering fuel
- Relay on the control board that powers the heater has failed
- High-limit device or thermal fuse has opened
- Igniter is weak or will not glow
- 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 Whirlpool dishwasher?
It is a fault code from the Whirlpool 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.
