F8E4 — Leak / Flood Detected (Water in Base Pan)
F8E4 means the flood/leak float in the base pan detected water, so the dishwasher runs its drain pump to protect itself. It indicates a leak or excess water in the base — NOT low fill. (Official Whirlpool/KitchenAid meaning.)

How to fix it
- Pull the dishwasher out and check underneath and at all hose connections for leaks.
- Confirm only dishwasher-rated detergent in the correct amount (suds can trip the float).
- Dry the base pan and inspect/test the float switch.
- Repair the leak source; replace the float switch or a leaking pump/seal as needed.
Why it happens
Typical signs: F8E4 shown on the display · Drain pump runs continuously · Standing water in the base / under the unit · Cycle stops or will not start
- Leak from a hose, connection, or pump seal Water collecting in the base pan trips the float.
- Excess suds or overfill Wrong detergent or too much can foam over and trip the float.
- Failed base-pan float switch A stuck or faulty float switch reports water when there is none.
