Error codeF6E4 (6-4)
ApplianceDishwasher
When the float switch in a Kenmore dishwasher reads open, F6E4 is the result. Kenmore HE and Elite HE units show it on a digital display, Global HE and MicroClean HE units list it too, and display-less models blink 6-4 on the Clean light.
Cause one: an obstruction at the float
See if the overfill float is sticking, or if something has lodged under it. Whatever is blocking it should be cleared out.
Cause two: a fill valve that will not close
An inlet valve stuck open lets water keep flowing into the tub, and the surplus trips the float switch.
Make sure the fill valve really cuts off the supply when the dishwasher is switched off.
If it does not, that valve is replaced.
Cause three: the float switch itself
A technician unplugs the unit and reads resistance through the switch. A healthy one shows close to 0 ohms while the tub is empty or nearly so. Infinite resistance means a new float switch.
Reach Kenmore dishwasher repair for the Bay Area at (415) 825-6393. When you phone about F6E4, share the model number and tell us what you found under the float.
Model compatibility: Kenmore reuses codes across series and model years, so F6E4 (6-4) may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
