Error codeF6E4
ApplianceDishwasher
Quick answer
F6E4 is the water float switch code. KitchenAid's guidance: make sure the dishwasher is level, then cycle power.
Model compatibility: KitchenAid 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.
Plain language
What this code means
The water float switch is listed as the potential cause of F6E4; check leveling and cycle power.
The first question: is it level?
Leveling is where the owner help for F6E4 starts. Its potential cause is the water float switch, with “Level Dishwasher, Cycle Power” as the advice.
Leveling and the float switch
KitchenAid explains that a dishwasher set up out of level may trip the overfill (floater) switch, producing this error. A method for leveling household appliances with a phone is also pointed to.
The two steps in order
Level check. This comes first on the page.
Power cycle. Plug-in dishwasher: remove the plug for half a minute, then reconnect. Hard-wired dishwasher: turn the breaker at the home panel off for half a minute, then on.
Nothing is said about adjusting feet or mounting. Shifting a built-in unit may not suit everyone, and calling for help is a fair choice then.
Service documents
The technician documents list the code too, and they name only the float switch as the cause, so there are no other parts to add for F6E4.
If it persists
Beyond leveling and a power cycle, owner help has nothing more. A code that comes back means a service call; tell us what has been checked.

Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
