Re: Testing for continuity Hotpoint wm76 heating element

Hi Iadom

Turning the drum by hand gives a slight grinding noise, on spin there are no noises such as bangs etc but you can hear the springs on the concrete block in the machine.

Thanks

Re: Testing for continuity Hotpoint wm76 heating element

Hi Guys

Cessna, i disconnected the pressure hose, same problem.

Iadom, I did as you suggested and pulled the inner drum towards me with fingers only and there is movement of about 1 – 1.5 inches and you can hear the springs at the top of the machine twanging away where they attach to the concrete block.

Having noticed this, i isloated the heating element and then ran the spin cycle and hey presto it worked. I unhooked the heating element and lo and behold there were two score marks where the drum was catching the element.

Now the interesting bit, i went of the back of the machine and found brown/ black dust caked to the lower half of the platic outer drum, the source looked like the big nut on the back of the plastic drum which im assuming houses the bearing.

I thought it may have been from the fan belt or carbon brushes but this was just in one place like it had been spilt there and no obvious sign of damage to the belt.

I know for certain the element has gone, could the bearing have gone too??

Re: Testing for continuity Hotpoint wm76 heating element

Thanks Cessna and Iadom.

Cessna i will check the pressure switch as you have suggested.

Iadom, can you let me know how to check for earh leakages/insulation please. Most grateful.

Secondly, i noticed the inner pcb the one where the pressure switch is located looked black. On closer inspection, i found one of the mounted transformers in the middle of the board and a few componenets ( not resistors, these were black and bulb like ) had a coating of fine black dust around them, like when a component blows and leaves a sooty trail.

I managed to get a few numbers off the pcb concerned these being:

Hotpoint 904 116 208 and
AKO 546655

Could this be the cause of the problems and if so isit easy to get a replacement part?

Thanks Guys
