What does the Hotpoint F01 error code mean?
The F01 code (sometimes shown as 1 flashing light) indicates that the dishwasher is not receiving water, or is taking too long to fill. This is almost always caused by an issue with the water supply rather than the machine itself.
🔍 Symptoms
- Machine starts its cycle but stops quickly without washing
- No sound of water entering the machine at the start of a cycle
- Display shows F01 shortly after the programme begins
- The wash cycle begins but dishes are dry and unwashed at the end
- You can hear the machine attempting to fill (inlet valve clicking) but no water flows
How to fix the HOTPOINT F01 error code
- Check that the water supply tap (usually located under the kitchen sink or behind the machine) is fully turned on.
- Inspect the inlet hose for any kinks, sharp bends, or areas where it may be pinched behind the machine.
- Turn off the water supply and unscrew the inlet hose from the back of the machine. Inside the machine’s inlet valve connection, there is a small mesh filter — clean this under a running tap.
- Check your household water pressure. If multiple taps in the house are running simultaneously, pressure may be too low for the dishwasher to fill properly.
- If the above checks are all fine, the water inlet solenoid valve on the machine itself may be faulty and require replacement.
Frequently Asked Questions (FAQ)
Q: My water is on but the dishwasher still shows F01 — what else could it be?
A: Check the inlet hose mesh filter first — limescale can completely block it over time. If clear, the inlet valve solenoid may have failed and needs replacing.
Q: Is the F01 fault the same on Hotpoint washing machines?
A: Similar codes exist on Hotpoint washing machines, but this guide is specific to dishwasher models. The fault logic is the same — a water supply or fill timeout issue.
Q: Can low water pressure cause F01? A: Yes. Hotpoint dishwashers require a minimum water pressure to open the inlet valve fully. In hard-water areas with scaled pipework, pressure can drop below the required level..
