What Does Error Code F6E4 Mean on a Kenmore Dishwasher?

Float switch open — water level too low.

F6E4 fires when the control board monitors the float switch and expects the tub to reach a target water level, but the float circuit reads open or the level stays too low within the allotted fill time. This distinguishes it from overfill or flood codes, where the float trips high. The board interprets the persistent low reading as inadequate fill, so it may pause the cycle or wash with too little water. Common triggers include weak supply pressure, a stuck float, or a blocked inlet screen.

Models affected: Whirlpool-platform Kenmore 665 Series dishwashers, and similar Kenmore models built on the Whirlpool control system
What owners report: Owners commonly report this appears mid-cycle or shortly after starting, often after plumbing work or when the under-sink supply valve isn't fully open. A frequent quick win is simply reopening the supply valve or clearing the inlet screen, since low pressure and slow fill are easy to overlook before suspecting the float itself.

Frequently Asked Questions

Can I keep using my Kenmore Dishwasher when error F6E4 appears? +

A reset only clears the stored F6E4 fault; if it returns, the water-level problem is still present.

This is a moderate job — a multimeter and some disassembly are usually involved.
