Washey
ParticipantJust a footnote – I changed the sensor, after modification with the new harness , although I think if you are careful enough ,you could modify the 5 pin plug by removing the section with the 2 mute wires on it so it fits the new 3 pin sensor , and after ten washes the Hotpoint has performed perfectly !!
A bit more life out of the old girlThanks for your invaluable help folks !!

ParticipantThanks Dave . Its reassuring to see that if you remove the 5 wire sensor and look at the pcb carefully ,you will find that there are the end 2 wires that have no contacts -so are unused !! We had a game trying to fit the new 5 wire plug into the bottom control pcb ,but that was because they cunningly put a plastic bar in the centre of the new plug so it does not fit !!
So after having changed the 2 plugs by pulling them apart carefully (they remind me of Scotchlock fittings ) and checking before and after with the multimeter for continuity and being sure we had got the wiring correct – we are away to go!
What a kerfuffell Andy !!

ParticipantHaving had a look , I see the harness trails down over the topside ,then drops down to the white circuit board /module , where its plugged in next to 2 others in a line , 5 wires in this plug !
I am a bit of a worrier and still cannot see why there are 5 wires and then you only use 3 ,what were the other two doing ???Does anyone really know ? lol

ParticipantI will look a bit later thanks !! I thought it was odd they included the harness as in my mind the old one is sufficient , but I was relutant to remove the older one from its plug and swap over onto new harness ,without knowing the part was an alternative item that wouldn’t damage the board !
Why the 5 wires ,are 2 pairs common I persume?

ParticipantSo what you mean is (I guess) you remove the old harness and install the new one which then has the 3 pin connector to fit the new sensor? Thanks for your comment by the way ,nice to be here (its my first post !!)
If this is the case then I wish they could include an instruction to tell you how to proceed lolWhy has the sensor 5 wires if 3 are sufficient , there must be 2 common pairs I persume?
