Hotpoint Ultima 1400 shows 'close door' despite door appearing shut

The problem

On a Hotpoint Ultima 1400 washing machine, the display initially shows 'select program' as normal, but after selecting a programme and pressing start it later flashes 'close door' even though the door is shut. The door interlock had already been replaced and the fault remained.

Likely cause

The machine is not receiving confirmation that the door is closed. As the replacement interlock did not cure it, the most strongly supported cause is that the interlock is not being properly actuated by the door catch, or the door is not closing fully because of a loose, broken or weak catch/spring, or a section of door seal obstructing closure.

What fixed it

Check that the door catch is correctly engaging and activating the interlock when the door closes. Inspect the catch for looseness, breakage or a broken spring, and check whether the door seal is peeling away at the opening rim and preventing proper closure. Lubricating the catch and interlock was also suggested. The exact repair actually carried out was not confirmed in the discussion.

Checks to try

• Confirmed the fault still occurred after replacing the door interlock
• Check whether the door catch is properly activating the interlock
• Check whether the door catch is loose or broken
• Check whether the door catch spring is broken
• Check whether the door seal is peeling away from the opening rim and preventing proper closure
