Re: Hotpoint washing machine strange motor action problem
Thanks Johnny, I’ll try a new pre-programmed EEPROM first then, but take a new module as well just in case.
How do you re-prgramme the EEPROM, by the way? I assume you need the Indesit hardware key, as shown on Partfinder, but do you need special Hotpoint software as well, presumably regularly updated? Is that software available outside the Hotpoint service network?
Re: Hotpoint washing machine strange motor action problem
Silly me, yes washer/dryer WD420G.
As an aside, I’ve just received Hotpoint’s new prices from 1 Jan 2006 – the module comes down in price by 5{e5d1b7155a01ef1f3b9c9968eaba33524ee81600d00d4be2b4d93ac2e58cec2d} and the EEPROM by 50{e5d1b7155a01ef1f3b9c9968eaba33524ee81600d00d4be2b4d93ac2e58cec2d}! Perhaps that says something about how many of these particular components they are selling!
Re: Hotpoint washing machine strange motor action problem
I’d like to resurrect this posting. Yesterday I went to a Hotpoint WM420G, 1200rpm machine, just over 12 months old and out of guarantee, second time it’s gone wrong, first time under warranty. The customer took a gamble and decided to call me out rather than claim on his “free” parts warranty. The drum works fine on both slow and fast spin cycles, but will not reverse tumble as normal during the wash cycle. Just a half-hearted third of a turn of the drum every now and again.
The motor and tacho winding resistnaces all measure OK (although the two stator halves have different resistances of 0.5 and 0.8 Ohm respectively – not sure if this is OK). Rotor resistances are around 2.5 Ohms all round, tacho around 200 Ohm. The power module looks fine – no signs of overheating or water damage.
I concluded it must be the power module, which I’ve agreed to order for the customer, but have now seen this thread, and fear I may have opened a can of worms. Perhaps I may need the EEPROM, wiring loom part or motor instead.
I could refer the customer to Hotpoint, but want to pursue it as I’d like to know the answer for next time. Has anyone gained more experience of this issue over the last six months since the last posting?
Re: Zanussi FLS1383W motor problem
No, I had replaced the PCB only on my first attempt, not the timer. When I went back equipped with new motor, PCB and timer, only the new timer was needed. The old motor and PCB are back in the machine and working fine.
Re: Zanussi FLS1383W motor problem
I solved this eventually last Friday. Turned out to be a fault in one of the fast cam switches in the timer. I only found this out by substituting a new timer. Motor, pcb and wiring were fine.
Re: Zanussi DE6744 dishwasher control module
Thanks for the input. I managed to solve it quickly on my next visit – having noticed a caution in the service manual about putting the two-pin power connector on the board the right way round. It’s the only connector that’s not keyed (although confusingly the board enclosure has keying slots) and I had put it on the wrong way round. Won’t make that mistage again!
Re: Zanussi DE6744 dishwasher control module
PNC 911888011, part no 1525785133 – I’m sure that’s right, as it’s from the Distriparts DVD. Thanks for the tips, I’ll certainly trace through the circuit continuity against the wiring diagram and double check the on/off switch as you suggest. I’ll post the outcome when I’ve solved it.
Re: Zanussi FLS1383W motor problem
Thanks for the tips, and reassurance. I took the part number for the module 1247052218 – from the Distriparts DVD, using the PNC from the machine – 91478057800. I’ve now printed off the circuit diagrams and will trace the continuity through the circuit as you suggest. I’ll post the outcome when I’ve solved it.
