What does the Whirlpool F6 error code mean?
F6 (or F06) is Whirlpool’s water inlet error code for dishwashers. The machine has not filled to the correct level within the fill timeout. This is most commonly caused by a closed tap, a kinked hose, or a blocked inlet filter.
🔍 Symptoms

- Error within the first few minutes of any programme

How to fix the Whirlpool F6 error code
- Check the water supply tap is open.
- Inspect the inlet hose for kinks.
- Clean the inlet mesh filter.
- Check water pressure.
- Replace the inlet valve solenoid if needed.
Frequently Asked Questions (FAQ)
Q: Why does my Whirlpool dishwasher show F6 only in winter?
A: In cold weather, if the water supply pipe passes through an unheated space (under-floor, garage, loft), it can partially or fully freeze. This restricts or stops water flow, causing F6. Insulate exposed pipework.
Q: Is F6 the same as the old Whirlpool ‘no fill’ light flashing fault?
A: Yes. Older Whirlpool dishwashers used flashing lights rather than numeric codes — a specific number of flashes corresponded to F6. The cause and fix are identical.
Q: Can I replace the Whirlpool inlet valve without a plumber?
A: Yes. Turn off the water supply at the tap, disconnect the inlet hose, unplug the machine, and the valve is accessible from the back. The replacement takes approximately 20 minutes.
