Error codeF6E4
ApplianceCooktop
F6E4 turns up on electric (radiant) cooktops. Whirlpool describes it as the keypad, also called the user interface, losing communication with the user interface control.
Reset routine
Cut power at the cooktop breaker (or at the plug) and wait one minute. Switch power on once more. For a minute, keep watching the display to see if F6E4 comes up again. When it stays away, check the cooktop operates normally.
If F6E4 keeps appearing
Stop using the cooktop and book a technician visit.
To get a technician out for a Whirlpool cooktop in San Francisco, call (415) 687-4102. Have F6E4, the model number and the outcome of your breaker reset ready. You can read about Whirlpool cooktop repair first.
Model compatibility: Whirlpool reuses codes across series and model years, so F6E4 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
