I have a hotpoint ultima wt741 , about 4yrs old , washing machine does not show that the door is closed , the red closed light does not now come on, and machine will not start. l have removed top of machine and removed and inspected the lock switch/sensor and unplugged connector , all looks ok. I have refitted the door lock but the machine still cannot 'see that the door is in the closed position' and will not start. It first started playing up when you tried to start a wash it would flash up 'DOOR' but if you opened and re-closed the door the door light would come on and the wash would instantly start....but now seems to have failed all together?

Any Ideas?

This thread was marked as solved. Here's a summary of the problem and the fix, generated from the discussion below.

Hotpoint Ultima WT741 not recognising closed door

The problem
A Hotpoint Ultima WT741 washing machine would not start because the red door closed light no longer came on. The fault began intermittently, showing 'DOOR' until the door was opened and re-closed, then progressed to not recognising the door as closed at all.
Likely cause
The strongest diagnosis in the discussion is a fault with the door interlock, or the door/latch not operating the interlock correctly. A damaged, loose or misaligned door catch lug was also suggested.
What fixed it
Recommended action was to inspect the door, latch and catch lug for damage or misalignment, check that the door seal was not preventing proper closure, and check the interlock connection if competent to do so. If these checks do not reveal an obvious issue, the discussion points to the door interlock assembly as the probable faulty part. The exact repair carried out was not confirmed.
Checks to try
  • Door lock/interlock removed and visually inspected
  • Connector to the door lock unplugged and refitted
  • Observed that the machine displayed 'DOOR' intermittently before failing completely
  • Advised to check the door catch lug for damage or looseness
  • Advised to check the door seal was not stopping the door closing properly
Parts or tools mentioned
  • Door interlock
  • Door latch/catch lug
  • WD40

Safety: Further diagnosis should be carried out by a suitably qualified appliance engineer.

It sounds like either a problem with the door or door latch not operating the door interlock properly, or the door interlock is faulty.

I think I may have the same problem. Moved house at the weekend, plumbed it in and all was fine. Went to do some washing the next day and the machine was dead. The display flashes for a split second when I switch the power off and back on, but then nothing. Have checked the plug, the socket and made sure the door is properly shut. Two young children so my washing is piling up - HELP!!

If the fault only occurred after moving house then the suspicion is that something happened during the move. The first thing I'd check is that the socket is ok by running another appliance from it but it looks like you've already done that. The suspicion is that either the door could have got twisted or otherwise damaged during transit or some connection (that may have already been dodgy or loose) has broken.

Apart from checking the door seems to be normal, and that the door catch lug that pushes into the door interlock when the door is closed isn't broken or come loose there isn't much else you can do. I would try spraying some WD40 into the door interlock and on the door catch to make sure they are closing nicely and also make sure the door seal hasn't partially come away from the door rim preventing the door closing properly either.

An experienced electrical DIYer may check the door interlock wires are all on ok but other than that you'll need to get it looked at.
