Hi
My mums washing is on the blink, my sister in law told me the water is not draining,so I checked the standpipe and all clear, I then checked the Grey outlet pipe and removed all water and it looks clear. I then checked the filter at the front and just found few coins and little bit of dust build , which I cleaned.
i removed the flexible rubber pipe near the pump and this is all looks clean and No blockage.

I have check the belt at the back and it looks all good and has good tension and i spins it around. When I turn the drum it has good resistance.

i have checked the Carbon bushes and they looked ok, as It had some life in it.

We did a fast wash test on empty load and the washing machine filled the water and the drums did short rotation clockwise and counter clockwise and then stops for 5 min and does the same again. Water drained out ,as I checked the drain pipe out is and the water was draining out, but it would not spin and the indicator where it usually indicates,wash, rinse, spin and end this does not light, it just stays in the wash and the door lock remains locked and the light indicator after 30min and the time stays 0:01 and the machine does not end and you can not stop it unless power off hold presses for 10-20 seconds.

Please see above the link for the images, I have checked the element and I get reading 31.4 on multi meter 200Ohms settings and the probe was put on the Live and Neutral terminal ,by pulling out the connector when checking the ohms.

I then took the motor out and checked the carbon brushes and it had about 25%-30% left on it , but this still should be ok to work for the motor I think, but I am not sure on this if I am correct or not.

i then checked with multimeter to check the motor and 1st two white wires I get the reading of 68.0 To 68.80 Ohms I think this is the sensor on the motor. These are the 2 white wires.

carbon brushes 3.2ohms reading. Black and Grey wire.

motor field winding 2.1ohms reading. Brown and red wire.

i did not check the pressure switch yet.

going from the above the Heating element and motor looks fine from the reading.

could it be Pcb Module ?

i would appreciated your advice.

It could be yes, but PCBs are not recommended to replace as they are often misdiagnosed and they cost a lot, with no return option.

Hi Andy

i saw this article Regarding the pcb failure, when you do replace pcb you have to buy the programmer on top of that and it is not worth it, as the pcb will Be around £100 and the pcb reader will be around £150 and for myself diy it is not worth it.

i might as buy another Hotpoint washing machine.

 

Thanks for your reply.

Yes it's not advisable. You may be able to get it tested at QER
