Good afternoon my name is ***** ***** I will assist with your query today.
If your confident the socket and plug fuse are ok, and your getting power to the appliance, start by checking with a multi meter if your getting power to the switch, since if the switch is faulty this would cause the fault. If the switch is working and your getting power at that point the fault will be with the PCB.
Most likely it will be a relay on the PCB, so you wont see any obvious scorch marks.
I can confirm there isnt a internal fuse (thermal or otherwise) which would result in the unit being completely dead.
Let me know how you get on checking the switch, and if you need any assistance finding the replacement part from part master or espares.
Hi Andrew, on looking at the parts diagram the PCB (587) also contains the switch (program dial), as this is a moulded unit its unlikely to be something you can service, so you looking at replacing part 587 if its the switch or the PCB anyway.
Part Master are doing it for £166 here.
Based on experience I would say its the PCB, I cant think what else it would be or what I would check next to rule it out.
The question is now if you think its an economical repair.
No problem Andrew, appreciate if you can rate the service received.
