Hi, I recently inherited the above model and was told it worked, but the dryer cut out occasionally.
It was delivered upside down and when I plugged it in, I got the Xmas lights of doom. After google directed me here, I tried the usual turn off and hit start/plug switch at the same time, which corrected the disco lights, but the machine still would not start. The door lock light flashes once then goes out.
After leaving it switched on for a period of time, I came back to find the wash light on but the door lock light flashing. Turning the machine off and back on, or holding the cancel button for a few seconds made the door lock light go out completely.
I fitted a new door mechanism this morning and still have the same fault, no door lock light unless I hold cancel in and then it flashes. Have had it on it’s side and brushes appear to be ok, but am wondering whether to just scrap it out. It’s clear someone has been in it before, as all the usual torx heads have been replaced with posidrives and I’ve had to remove the control panel and refit all knobs and switches, as none of them were clipped in properly.
I did notice that there was a plug not connected to the main pcb at the rear, and plugged it into the board but nothing happened, so assume it’s surplus wiring/generic harness.
I’m frustrated as hell right now because I don’t admit defeat easily (I kept a Hotpoint Mistrall FF72S going for 15 years before throwing in the towel). I know the C17 capacitor can blow on these, but am I missing something with the lights? When I press and hold the start/cancel button, the wash, rinse and spin and final spin lights illuminate and then just the wash lights go out.
I’ve had it on it’s front to inspect the brushes and just performed the hold start/cancel and this time door locked, wash, rinse and spin and final spin lit up (no dry light on), this time the final spin has stayed on instead of the wash light.. Any ideas?Re: Hotpoint WD420 not starting
Had both boards out today for a visual and nothing seems to be amiss, c17 isn’t domed and both boards look clean.
Don’t understand why tipping it up changed it from “wash” to “spin” on the dash lights though.
If I knew that, I might be halfway to diagnosing the fault. I hadn’t had the control panel off at this point either.Re: Hotpoint WD420 not starting
TBH if a customer rang me and told me the machine had been tipped upside down I would sigh heavily and put the phone down. 🙁
AFAIK there are no surplus wiring plugs to the main pcb??
Re: Hotpoint WD420 not starting
I would get rid of it normally either the door lock or the brushes cause this problem which you have checked,the only other thing for you to check is the motor wiring and the door lock wiring if these are fine you could well be looking at a pcb fault, also i can see the dryer worked now and again if there is a fault on the dryer that can cause the wash side not to work properley also. but if every light on the machine flashes this is a pcb fault.
Re: Hotpoint WD420 not starting
What I’m getting now is just a slow blink of the door lock light. If I switch it on and then press ‘start/cancel’ and hols that for a second or two, all except the ‘dry’ light flash up once, then go out, then the ‘final spin’ light comes on, on its own.
If left, after about two to three minutes the door lock light starts to slowly flash whilst the ‘final spin’ light stays on.Re: Hotpoint WD420 not starting

There’s one not connected on the harness at the top as well… It’s the harness that sits on the very top right.
Will take pics of both plugs and pcb once I have the camera working on the phone.
From memory the one not attached to the main pcb has four wires, two orange, two black. I know it’s not helpful without pics though.Re: Hotpoint WD420 not starting

Not every light flashes, you just get one single flash from the first four of five horizontal lights and all five vertical lights flash once when you press and hold the start button, then the final spin light illuminates on it’s own.
About 3 minutes after this, the door lock
comes on and starts to blink slowly.
If you press any of the vertical lights in, they blink about 5 times in rapid succession and then go out, but only if you press the switch, otherwise they only
once for one second when you hold the start button.Re: Hotpoint WD420 not starting
After reading another post about a common Ariston fault, I’ve just noticed that the main wash dial clicks all the way around in both directions, should it be able to do that?
Re: Hotpoint WD420 not starting
Like all basic rotary switches fitted to modern pcb’s it can be rotated in both directions.
The wiring connections on WD420 machines changed from date code 39.
Unfortunately the manuals do not give colour codes for the wiring but there are 10 connection blocks fitted to the main pcb.
This will be my last post in this thread for two reasons,
1: Any machine that has been tipped upside down will in most cases have suffered damage of some sort, usually serious.
2: The fact that the drum halves are secured by substitute screws implies that this machine has been ‘repaired’ by a bodger at some point in its life, god knows what else he/she has done to the machine. 😯
