Hotpoint Washing Machine WMUD 9427 Not filling with water

Hi Ben,

It sounds like the original drain fault may now be cleared, but the machine is either not being told to fill, or it thinks a condition has already been met so it just sits there counting down.

Before checking anything internal, isolate the washing machine from the mains.

1. Check the water supply first Make sure the inlet tap is fully on and the fill hose isn’t kinked. Unscrew the inlet hose at the machine end and check the little filter gauze in the inlet valve for blockage.

2. Listen for the inlet valve Start a wash programme and listen carefully. If you hear a faint hum but no water enters, suspect a blocked or failed inlet valve, or poor water supply. If there is no sound at all, the valve may not be getting power, or the control isn’t calling for fill.

3. Recheck the pressure system If the pressure chamber or pressure switch hose is partially blocked, the machine can think it is already full and refuse to fill. Check the thin pressure hose for splits, kinks or soap gunge, and make sure the chamber connection is clear.

4. Door lock behaviour The door locking as soon as the door is shut suggests either the lock is being energised incorrectly, or the control board is misreading the lock circuit. If the lock proves closed when it shouldn’t, the programme can behave oddly.

5. If possible, inspect wiring/connectors Pay particular attention to wiring to the door lock, pressure switch and inlet valves. A disturbed or corroded connector can cause this sort of fault.

If water supply, valve filter and pressure hose are all fine, the likely suspects are the inlet valve, pressure switch system, door interlock, or the main PCB. Any live electrical testing should be left to a qualified appliance engineer.
