Help! wiring diagram for main circuit board-hotpoint washing machine wf101

brousuka

Could somebody please show me the correct plug ins for the above? i took a photo before i disassembled it but it got wiped on my PC! I think I plugged the wrong connector block in somewhere as the machine is not working properly. I've tried online everywhere but can't seem to find it. I will upload photo's later of what I did. Thanks in advance!

what lights are flashing on the front panel ? and why did you disconnect the board ?

You could try searching for and unerasing the file on your PC. Lots of suitable programs available on the net .. I use one called Recuva.

Sorry, should have elaborated more; I replaced a faulty capacitor on the pcb, it solves the flashing lights problem all the lights were flashing. At the moment it seems to be stuck on the first cycle and not heating water. There are no flashing lights now, i am concerned that I might have put a wrong connector back on the main board. Thanks.

Before I explain further , how did you diagnose a faulty capacitor ?

oh dear!

Found the solution on diynot forum:...............
Fault - worked fine sometimes, all lights flashing sometimes, sometimes failing in mid program. Several sites suggested it was the main PCB at fault.

I decided to take a good look at the PCB first, rather than chase a replacement. Round the back of the machine, you remove a small oval plastic cover, remove the self tapper below it which retains the PCB's casing, then take off the much larger belt/motor access panel too wiggle out the PCB in its white case. Take careful note of what connections go where as the unit is unplugged.

C17, a 680uF 10v electrolytic cap had some mild signs of swelling on top, so I replaced it with new 1000uf 10v from my stock. Which has completely fixed the problem.

Obviously I'm not sure whether this was a one off faulty capacitor on our machine, or whether it might be more widespread. If a design error it might be better to replace the 10v electrolytic with a 16v version.

The lights were flashing because that indicates an error.Dependingon the sequence of the light flashing it refers to different faults.It is difficult to fit connectors to the pcb incorrectly.

id say you have misdiagnosed the fault

do yourself a favour and ring hotpoint ,give them 113 euro and let them replace board and diagnose the fault correctly - cheaper in the long run

as an aside ,i have a pain in my tits with customers ringing me up and telling me what the fault is with thier machine after reading it on the internet ,quoting price parts from espares and looking for me to do a job cheap -95% of the time they are wrong

op- the flashing lights on a hotpoint is signaling a fault code usually read and diciphered by an engineer - this points to the cause of the problem

when you changed the capacitor you might have replaced a blown componant but didnt fix why it blew in the first place

at a guess i would say you could have interfered with the software or epprom when you were at the board

Thanks for the comments, I take on board what you say (no pun intended)! as for the flashing lights all of them were flashing like a christmas tree but at one point i seem to remember that the final spin light (5th) illuminated on it's own for a while. I just came across that forum and the problem seemed to be sorted very well at low cost and I thought I'd give it a try, it's just that i've laid out so much money lately on things to be repaired etc!!

Actually, electrolytic capacitors can, and do fail in exactly that manner (bulging and leaking) all by themselves, esp. if underrated voltage-wise. Also in recent times there have been many recorded incidents of substandard electrolytic capacitors from Taiwan cropping up in all manner of consumer electronics, especially power supplies and computer mainboard voltage regulators.

actually ,you may be correct ,as with all capacitors the visual signs are the same but given i have specific product knowledge i would like yourself ,guess that there was a problem elsewhere to maybe cause the cap to blow ,signaled by the built in fault diagnostics which communicates through flashing sequenced lights . i would say that the lights showed f 15 heater relay welded closed (four of the five lights like a christmas tree?)
this would or could cause the cap to blow if it was blown -

but its just a guess as i would have to see the machine

Just to let you guys know I changed the brown and blue wires from the heater to different lugs on the control board (they were in the wrong order) and hey presto the machine is working fine! problem was solved. So it was actually the capacitor. Hopefully I will have clean clothes for many a day to come.
