hotpoint problem

[DDSDDS]

i have hotpoint wf840 this machine goes through the cycle perfectly once it gets to the end of the cycle it spins off as usual and then when you look again it has reset to about 40 minutes and goes through the cycle again
i have checked continuity through the heating element and that is fine anyone else got any ideas other than power board.

Thanks

Re: hotpoint problem

don’t just check continuity of element – check insulation resistance as well- if this is low it may cause this fault, anything below 30 ohms may be dodgy

He means 30 Megohms.

Re: hotpoint problem

right have checked that i get no earth leakage

as for the fault
it gets down to 0 and displays wash rinse and spin
then it resets to 44 minutes and will count all the way down again and then finish the cycle normally
this to me seems like the machine resets the time at certain points for the display but it is struggling to complete whatever task should be done for the 44 minute display i am going to strip down the pump and pressure system as i think this may be related
if any one else has any ideas they are welcome and if i do get it sussed or learn anything else new i will update this thread for future reference

Had a similar fault on a similar model (assuming that it’s the one with the control board at the rear low down on the right hand side. I ended up reprogramming it as it seemed to be a glitch on the board itself.

Re: hotpoint problem

that is my next thing to try but just want to make sure first
will keep you posted

Re: hotpoint problem

its an appox time but can extend the time if it needs to in short there isno fault have you timed it using your watch had same fault last year this was info i sourced

Re: hotpoint problem

i am fully aware that they time down and auto adjust but this machine gets right down then adds on 44 minutes
i have had it running with different loads next to an identical machine and they both get down to zero at the same time then this one starts again
the initial wash estimate of roughly 1:25 now takes well over 2 hours

Re: hotpoint problem

Not logical, assuming earth leakage checks perfomed correctly, so the computer is borked.

Re: hotpoint problem

just to update this thread i left the applaince on one side for a bit then got in a smart card this did not cure the fault
i then got a little angry and changed valves pressure switch motor pump and front display board and heater
still same fault
i then aquired a working board from a doner machine (i have a testing rig to run these through a wash) the board was fine i fitted to the machine it got to 4 mins the display said wash rinse and spin then 3 mins then 44 mins exactly the same as the last pcb sthe display still highlighted was rinse and spin but proceeds to do a rinse and then after 44 mins it finishes properly it is the same result whenever you run it through a heated wash whether or not you turn off the heat
also worth noting is after the initial warm water is dumped 44 mins is displayed

i then removed the second pcb and restested on my rig and it too now does the 44 minute thing every time
so when all is said and done
it aint the motor front board pressure switch pump heater or valves but whatever is wrong either damages the pcb or the software so i now have 2 duff pcb’s and one wf840 in a million pieces going to scrap

Re: hotpoint problem

had a similar sort of problem with a WF cant remember what model exactly but it turned out to be a dodgy inlet valve ❓

Re: hotpoint problem

Jeez, thats a strange one 😯

Re: hotpoint problem

Did you check the motor .. I have had similar problems before, albeit with different hotpoint, indesit and beko models, however changing the motor-tacho or sometimes the whole motor has fixed the problem in those cases

Re: hotpoint problem

strange was not the word this has been a bit of a project for me but as i said i have changed the motor and the valve every electronic component has been changed
the only thing original would be the mains lead and wiring loom all the part checked out ok and most came from an identical but cosmetically knackered (think it was rolled down the drive by the previous owner or at least that is what it looked like) machine i scrapped a week or 2 ago
i am just hoping the fault on the board is software then i can just reprogram it and have a couple more spare boards
