What Does Error F03 Mean?
The Hotpoint washing machine error F03 indicates a malfunction related to the temperature sensing mechanism, often resulting in the machine failing to heat water properly. This can lead to the washer stopping mid-cycle and displaying the F03 error code on the control panel.

- Cold water throughout the wash
- Error code F03 displayed on the control panel
Possible Causes
- Faulty NTC temperature sensor (thermistor) (medium)
- Loose/corroded wiring or connector to the temperature sensor (medium)
- Fault in control board temperature circuit (low)
How to Fix Error F03
DIY Fix Basic checks and reset
- Turn off and unplug the washing machine for 2–3 minutes
- Plug back in and restart a cycle to see if the code clears
