Kenmore Dishwasher F8E4 — What It Means & How to Fix It
Also shown as F8 E4, flood code on some models.
F8E4 is the Whirlpool-built Kenmore 665 dishwasher's flood code - the float detected water in the bottom of the machine.
What this code means
On Whirlpool-built Kenmore 665 dishwashers, F8E4 surfaces in diagnostic/service readings as the flood fault: the float switch in the base pan detected water. It means the machine found liquid where it shouldn't be - a real leak or a tripped float - and service is warranted if water is confirmed.
Verify against the model number printed on the tub or door edge: this is the Whirlpool-built Kenmore 665 dishwasher family, and F8E4 is its flood/base-pan code per Whirlpool-family dishwasher fault-code references.
Most likely causes
| Cause | How likely | DIY-fixable? |
|---|---|---|
| Water leak inside the unit (fill valve, pump, sump, or connectors) | Common | No - internal leak location is a tech's job. |
| Backup from a blocked drain climbing into the base pan | Occasional | Cautious - clear visible drain clogs, then reassess. |
| Stuck or faulty float switch triggering a false flood | Less common | No - float servicing involves pulling the base assembly. |
What you can try yourself
- Turn the dishwasher OFF at the breaker or unplug it immediately - flood alerts and live power don't mix.
- Check the floor under and around the unit and dry up any pooled water before going further.
- Inspect for an obvious cause you can safely address, like a blocked drain stub-out under the sink feeding water back.
- If water was truly in the base pan, schedule a technician - internal leaks and float diagnosis need service diagnostics.
Seeing the symptom rather than the code? Dishwasher leak alarm: checks that apply across brands.
When to call a technician
- Stop at the first sign of internal leakage: peeling back the base and chasing seals can turn a $150 repair into a claim.
- Stop if you see water near the unit's electrical connections - leave the panel work to a licensed tech.
Typical professional repair cost: $150-$400
Frequently asked questions
Is F8E4 a common Kenmore dishwasher code?
It's specific to the Whirlpool-built 665 family's diagnostic set - other Kenmore builders use different flood indicators.
Why does my dishwasher show F8E4 with no visible water?
A faulty float switch can trigger the flood code without a real leak - a fluid-level test from a tech will tell which it is.
