The spider broke. I have replaced that along with the bearings etc and it generally runs smoothly but there is still quite a bit of vibration with a heavy load. The suspension struts seemed firm enough but is replacing them, the machine is about 4 years old I guess, going to improve matters as there seems little else to try.
The out-of-true drum also took out the heater which I have replaced. Despite this. the machine still doesn’t wait on Program C waiting for the water to get up to 95C, it just ploughs on regardless. Does the thermistor on the heater element do all the temperature sensing as I hadn’t noticed any other thermostat. If so, what is the most likely cause of it not bothering with the temperature. The old thermister appears to have been behaving correctly i.e. dropping from about 15K down to 2K or so.
Lastly, is there ANY chance of getting my hands on a circuit diagram. It seems they aren’t readily available.
TIA

That could be a loose concrete weight, or maybe just your workmanship 🙁 Im very sorry if I insult you, but I guess your not a professional appliance repairer.

That thermistor does do all the temperature sensing, these rarely go faulty 😕 My guess would be that the machine doesn’t have time do get to that temperature on a ‘C’ wash. I reckon Iadom can confirm/correct this next time he’s online (we all just left the national meeting about 4 hours ago 🙂 )

Nope 🙁 You’ve got more chance of winning the lottery, twice!
I’m sure you know all ready, but unplug the machine before any mantainance.

The thermistor is the only temperature control in this machine, if all of your wiring is intact, then the control unit itself could be faulty, even if the timer is fine, it will however advance to the rinse & spin programmes if it does not sense a rise in temperature after a set period of time so heater wiring could be faulty if new heater is OK.
A simple and safe way to check if the heater is in fact working is to set the machine on and after 3 or 4 minutes check your electricity meter, the old style meter will have the disc spinning rapidly, the later type will have the red neon indicator flashing quickly.
Re: Hotpoint WM63P several issues
On programe a 95’c wash it is a hot fill if the incoming water is above 55’c it does’nt heat the water until the heat step after programe E upon which it will heat up to 95’c, saying that if there is a broken thermistor wire it will advance through heat steps likewise if the heater is open circuit and there is no rise in temperature detected the heat step is aborted hope this helps.
Re: Hotpoint WM63P several issues
Thanks all for the various points.
Goatboy… Fair comment but I’m pretty sure the new bearings are installed OK. I’ll take a close look at the weights.
The machine is getting a hot fill, so I’ll check to see if it heats during the E program heat cycle, thanks for that.
Pity the diagram isn’t available, it would make things SOOOO much easier. A new board at £85 is out of the question anyway.
Cheers

Despite your aspersions on my abilities… you’re still my hero because indeed the bottom weight was loose and since tightening it up this morning, the machine is back to it’s old self.
Thanks for the useful suggestion.

Sweet! Thanks for the new signiture. That kinda sums Goatboy up!
