Error codeF6E4
ApplianceDishwasher
The water float switch is the potential cause named for F6E4 on a Whirlpool built-in dishwasher. Two owner actions come with it: check the level of the unit and cycle power.
Leveling
The part involved is the overfill (floater) switch, and incorrect leveling can actuate it. That makes the level of the dishwasher the first thing to check; a unit that leans can produce the code on its own.
Power cycle
Remove power from the dishwasher for 30 seconds: unplug an outlet-connected unit, or switch off the home-panel breaker of a hard-wired one.
Restore power.
See whether F6E4 comes back.
A reset can sometimes clear a fault, much like restarting a computer. If F6E4 appears again once the unit is level and the power cycle is done, the next step is a technician visit.
Whirlpool dishwasher service for F6E4 in San Francisco and the Bay Area is booked on (415) 687-4102. Mention whether the unit was checked for level and what the power cycle did, and have the model number handy. The Whirlpool dishwasher repair page has more.
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.
