Hi Graham,Thank you for using Just Answer my name is ***** ***** I will help with you question. My first thought is that it probably is repairable if the parts are available. It could be one of a few things that are causeing it not to turn.It could be the belt has snapped if this is the case I would expect it to be cost effective to repair. It could be the capacitor that starts and runs the motor again if it is this it to be cost effective to repair. It could be the motor brushes again if it is that it would be cost effective to repair.It could be the motor if it is the motor it may not be worth repairing.
If you wanted I could talk you through checking a few bits yourself you would need to take the top off the drier and it should only be a couple of screws.
HI Graham,I have just checked with a supplier I use and they are showing a large range of spares still available including a motor at £70 + vat and the motor is the worst case.
