hotpoint washer

[Andy™]

ive got a dead hotpoint WML560 washer. when its switched on it on door locks & fills with water as normal then nothing. no spin. usual LEDs are on (power, door locked and where in the program it is). seems to be either the PCB not powering the motor or the motor not working.  if you leave it for a while it does not progress further into the program so probably the PCB

anyone know how the motor works? there is a 7 way connector (exc earth) with 5 black and 2 red (which are for the speed i think). one of the blacks is live but nothing else

edit: pin 2 of the blacks is live at 230v. 1 3 4 & 5 have between 20 & 40v (all with reference to neutral)

edit 2: found it fault, brush not fully making contact... should have ripped the motor out first

It is usually the brushes worn if everything else is working as per it should. 

You can pick up the brushes for a few quid, quick change and all is good again.

already ordered some, it was just the fact that it didnt go further through the program that made me think it was the PCB. that and the motor has a tacho so would have expected some kind of error when it didnt detect motor spinning when it should have been

I'd have chucked it out before it spontaneously  combusted!

I used to work on industrial laundrette equipment, an interesting thing about the brushes going, is you do get a warning, before they fail completely they don't spin as fast, resulting in clothes coming out damp.

When a programme doesn't advance it's quite often one of two things, either the pulse motor on the programmer is knacked, or the line to the pressure switch is blocked, it uses the pressure switch to sense there is the right amount of water in the drum before it advances the programme.

top tip with washing machines, if the rubber door seal is not kept clean inside it can develop a hole, sooner rather than later, if this happens then simply release it and rotate it 180 degrees, the hole is now at the top, it won't leak water, and you can keep the wife happy until you can get a new one.

either the pulse motor on the programmer is knacked

Not seen one of those for an few years!

I got called out to work on a washing machine a couple of weeks ago!

Ok so I know the industrial look is all the rage in modern houses but that's taking it a bit too far!

Hospital perhaps?, worked on some dishwashers that size a few years back.

Well central hospital laundry for about 8 hospitals.

 

[Andy™]

at least you have a manual for it

 

[Sidewinder]

Hmm, manual is a mute point.

It's not very good, and there is a lot of information missing, it doesn't comply with the requirements for a manual under the Supply of Machinery Safety Regulations by a long shot.

Glad it was just brushes, at least it's a cheap fix. Most of the newer domestic machines are inverter driven motors nowadays and not so easy to fix.
