Hotpoint (UK) Washer F03 Error Code

Temperature sensor fault: not heating. Here is what it means and how to clear it, easiest fix first.

F03
May need a pro

The machine cannot read the water temperature correctly, so it may stop heating on wash settings (and dry settings on washer dryers). This usually points to the temperature sensor (thermistor) or its wiring.

Applies to UK/European Hotpoint machines only, not GE-made Hotpoint washers sold in the US. Indesit's UK service site lists the same code with the same meaning.

Safety first: unplug the washer (or switch off its breaker) before touching filters, hoses or panels. If you smell burning or gas, or see water near the outlet, stop and call a professional.

How to fix Hotpoint (UK) F03

  1. Try one reset

    Switch the machine off and unplug it. If there is water near the outlet or cord, switch off the circuit breaker instead of touching the plug. Wait a couple of minutes, plug it back in and run a warm wash to see if the code returns.

  2. Note the details for the technician

    Write down the code, the program you were running and the model and serial numbers from the label inside the door. This helps the technician bring the right parts.

When to call a technician

If the code returns, book a technician to test the temperature sensor and heater.
