What does the Whirlpool F7 error code mean?
F7 (or F07) relates to the turbidity sensor — the component that detects how dirty the wash water is. A faulty or limescale-coated sensor can cause the machine to repeat wash phases unnecessarily or fail to complete a cycle.
🔍 Symptoms
- Extremely long cycle times — 3+ hours on a standard programme
- Machine appears stuck in wash phase
- Cycle repeats the main wash phase multiple times
- Dishes are actually clean but machine will not progress to rinse
- Error appears mid-cycle during the wash phase
How to fix the Whirlpool F7 error code
- Locate and clean the turbidity sensor — it is in the sump area near the filter. Wipe the sensor lens with a soft cloth to remove limescale or grease.
- Run a dishwasher descaling product to tackle limescale throughout the machine.
- Clean the filter thoroughly.
- Reset the machine by powering off for 10 minutes.
- Replace the turbidity sensor if cleaning does not resolve the issue.
Frequently Asked Questions (FAQ)
Q: What does a turbidity sensor look like in a Whirlpool dishwasher?
A: It is a small plastic component, roughly the size of a 20p coin, often with a clear or semi-transparent window. It is located in the sump area near the filter assembly.
Q: Can I clean the turbidity sensor myself without removing it?
A: Yes. With the filter removed, the sensor is accessible from the bottom of the tub. Wipe the lens with a damp cloth or soft brush — no removal is necessary for a basic clean.
Q: Will the F7 fault cause damage if ignored?
A: The machine will continue to run but cycles will be very long or incomplete. It will consume significantly more water and energy than a machine working correctly.
