What does the Whirlpool F8 error code mean?
F8 (or F08) means the anti-overflow or flood protection system has been triggered. Water has collected in the base tray of the machine, lifting the float switch. The machine will not operate until the tray is drained and the leak source is repaired.
🔍 Symptoms

How to fix the Whirlpool F8 error code
- Unplug immediately.
- Tilt the machine forward 45 degrees to drain the base tray.
- Allow 24+ hours to dry fully.
- Reconnect and run a short test cycle while observing for leaks.
- Find and repair the leak — door seal, hose connections, and sump seals are the most common locations.
Frequently Asked Questions (FAQ)
Q: Why is my Whirlpool dishwasher continuously draining (pump running all the time) after F8?
A: The drain pump runs continuously when the float switch is raised — this is the machine trying to empty the base tray. Once the tray is drained and the float drops, the pump will stop.
Q: I tilted the Whirlpool dishwasher but F8 is still showing — why?
A: Either the base tray is not fully dry yet, or the float switch has become physically stuck in the raised position. Gently press the float switch down to its rest position from inside the base tray.
Q: Does F8 on a Whirlpool dishwasher always mean a serious leak?
A: Not always. Excess detergent foam can overflow from the tub into the base, triggering F8 with no actual leak present. Check this possibility if it happens only once.
