Hotpoint VTD00 tumble dryer stopping in cycle

Are you saying that it spins only one direction regardless of live connected to red or black?

Of course, spinning by hand it will freely spin in whatever direction you spin it in.

This is an induction motor!

If I spin the motor in either direction then apply power it drives in that same direction. From stationary with the application of power it drives in either direction, not always in the opposite direction to the previously wired operation. (No, that doesn't sound sensible)

 

[yardie]

Are you waiting for it to stop spinning before changing the wiring?

 

[planenut]

Definitely yes.

 

[yardie]

It should always spin in the same direction when connected to one wire and opposite direction when connected to the other, so sounds like you do have a suspect motor.

Windings probably shorted which would explain sometimes changes direction and sometimes not when switching the wiring configuration.

Many thanks again for your time. I'll try to borrow a motor and will post the result.

I'm not entirely convinced the motor is at fault.

What has been missed is the fact that the cap needs to be connected as well.

Cap with 4 lugs (if you only have 2 lugs and use piggy back connectors the same principle applies)

Connect live to one side of the cap only!
The red and black of the motor then connects to each side of the cap.
The white connecs to the neutral.

Which way does it spin?

Now switch the live to the other side of the cap.

Which way does it spin now?

You should also notice that the motor kicks in with a bit more power!

You will find your motor is fine. Still convinced its the timer.

Lucky I'm not colour blind - well as you suspected, with those connections, first anti-clock. then the second clockwise. Nice one. and you are right about the extra umph.

 

[yardie]

So, are you now happy and convinced its not the motor?

Let me know and we shall proceed to the next step.

 

[planenut]

So, are you now happy and convinced its not the motor?

I am, and thank you for your guidance. I'll have another go at the timer.

I really appreciate all the time you have given me on this.

 

[yardie]

No problem at all. Glad to help.

Yes, most likely the timer. Some can be easily opened and contacts cleaned. 2nd handvrelatively cheap on ebay.

As said before unlikely to be the relay but just to be sure could you trace the wires and note where they go.

 

[planenut]

Right that's a job for a winter evening, ah, that'll be this evening then.

 

[yardie]

At least you have the comfort of working indoors, I'm outside working on dishwashers!

I've just spent another hour outside on a cooker, oh the feet.

sorry gang, just to resume where I left off - having checked all the wiring is in the right place, we have a sort of "impasse" when it comes to the reversing of the tumble, i.e. it will run then when it gets to the reversal, it just buzzes from the motor as if it's receiving two opposing instructions. Changed the timer but with the same result.
