Hotpoint WMTL80

[AMS]

I’m hoping someone can help me with a problem I’m having with this top loader. Customer ordered and fitted a replacement module direct from Indesit. The old one was blown. Big surprise, didn’t work. it was at this point that I was called in (reluctantly). After playing with it for a while, I found that it didn’t have an eeprom fitted and the one on the original board was non-removeable. Gave her the choice of obtaining an eeprom and using the new board or sending the original to EMW for repair. She chose the latter. Fitted the repaired board and all seemed well apart from no motor action because the pulley lock would not withdraw. With the belt off and manually making the lock microswitch I could get the motor to work. Con checked the wiring from the board down to and through the pulley lock solenoid and all seem ok. The solenoid is the reddy-brown type like the one on a neff/bosch etc dishwasher dispenser. I’m getting about 1.6 kohms across it. Is that OK? There is a plug break in the wiring down to the lock, so I split it and measured across it. I’m getting 240v live to earth but nothing live to neutral. I think that is my problem(no neutral), but where do I go from here? Phoned EMW who were fairly sure that the problem was not a board one, but would readily accept it back for checking, and confirmed that the damage to the original board was caused by the interlock. Now this machine has a lid interlock just like your conventional front loader door lock, but the lid does lock and the led on the control panel confirms this.
So where do I go from here? Could the lid interlock be at fault? Has anyone got a wiring diagram they could send me(Jim?).
I have half considered removing the pulley lock altogether. As far as I can see, the sole purpose of the thing is to lock the drum at top dead centre so the drum flaps are accessable. Would it be such a problem to have to move the drum manually?
Please help me as I’ve invested quite alot of time (and money) in this so far. 😥

Cheers all,

Dave

Re: Hotpoint WMTL80

I did not understand which lock was found faulty (which has generated PCB fault) because, from what did you said, I understand that lid lock is working (because power led light).

There are two locks:
-One with three wires (3=”live” & F7 & second lock live & drain pump; 2=”contact” & F6 & power Led & heater; 1= “neutral” & F4) (F4; F6; F7=pin’s from connector “F”)

-One with four wires (one pin of thermal resistor goes to “live” earlier described and other one to Pin 4 (bigger connector with four wires). and other two wires (switch) to C7 & C8. Do not connect any of those wires for thermal resistor to this pin’s….

Re: Hotpoint WMTL80

Thanks for the reply Baron. EMW who are the pcb repair experts here in the UK, said that the original board has the classic signs of interlock failure. However, with the new(reconditioned) pcb fitted, the lid interlock locks and indicates locked and the machine works as normal, except that the drum pulley lock does not disengage to allow motor action.
Does anyone have a wiring diagram or technical information on this model? I’m particularly thinking of Jim(Iadom) 🙂

I just told where goes all wires related to the both locks… but if you really need diagram give one email address…
