ISE 5, (serial number begins 0061) Error code E01

[Mutttley]

E01 is given as “door not closed” so the prime suspect is the door sensor/lock. I have looked at it with a continuity checker and cannot detect any switch function – but I’m not sure how it works, there is no obvious switch, so I suspect it does it by trying to lock the door and detecting if the lock pawl is prevented from closing.
The only question I have is, is E01 likely to be caused by anything else? I can’t think of anything myself, but the fact that I can’t be sure I’m testing the lock/sensor properly makes me slightly unsure.
I note that the part is available and not too expensive, but I’m never very happy about “replacing parts until you find the one that’s broken”.

Edit: The lock I have looks like this one

which mentions only ISE2 in its listing.

with that type of door lock you wont detect any switch functions till it locked

there small 240 volt heater inside the unit. when you start the machine the timer turns on the heater that locks the door at the same time as closing the contact so the machine will start

they do fail but there are other things that will stop them operating. it is most likely just a failed lock but I cant promise

Thanks for the explanation. I’ve ordered the part from the site shop, and will get back once I’ve fitted it. I’m glad it’s so easy to get the front off the ISE 5, as there wasn’t enough slack in the wiring to get the switch out just by removing the door/drum seal.

As promised, update on the fix.
Part arrived this morning, taking a little longer than I’d expected, but I did choose the cheapest delivery method. The part is identical to the one removed from the machine, so fitting it is easy. The hardest part is getting the door seal properly re-engaged all round the opening in the machine front.
Machine is now on its second load, the fix seems to have done the job :tup:
Being nosey, I decided to disassemble the failed lock switch. This is not easy, as it was (fairly reasonably) not meant to be disassembled. Once inside, the failure is seen to be caused by part of the resin switch casing suffering from the repeated heat loads of the lock mechanism, as explained by electrofix up above. The resin posts that held the heated block in place had eventually charred and crumbled, allowing the element to move back to the point where it could no longer activate the over-center spring. Possibly fixable, but getting the switch apart was risky, and I was lucky to not break anything. Only one place where there is danger of pingfsckit, and that’s on the latch slider itself, where the return spring is likely to fly once the switch body has been removed.
It has given over ten years of service, so I’m not saying it owes us anything. Thank goodness for error codes that narrow down the failure location too 🙂
