Hiya,
How are your diy skills?
Do you have, and can you use, a multimeter?
Have you checked the fuse in the plug and the socket it's plugged into?

Thanks

DIY skills are good. Fuse & socket OK

Hiya,
and the multimeter?

Thanks

Hiya,
OK, thanks for that.

Unplug the appliance.
Take the top off.
Test for continuity between the plug top and the mains filter at the top rear.

If all ok, take the rear panel off and take the main board out.
Trace the wiring from the mains filter to the board and test that for continuity.

Check the pcb for obvious damage while you have it out, you'll need to take it out of the plastic housing.

Let me know what you find.

Thanks
Customer: replied 3 years ago.

Continuity ok to mainboard can't see anything obvious on the board. Electrolytic caps not domed.

Expert:  Techdesk replied 3 years ago.
Hiya,
Ok, you need to make sure power is getting to the board.

If it is, your board is the likely cause.

Thanks

Think I have found the problem. There is a power diode with one terminal melted leaving no connection. The large resistor next to it reads 15 ohmns but had burnt crud on it.

Expert:  Techdesk replied 3 years ago.
Hiya,
Thanks for letting me know.

If you are replacing the board with new, it has to be programmed after fitting.
This requires special equipment.

Www.emwelec.co.uk can repair your board, no prang ramming needed then.

If you can repair it yourself, even better.

Hope this helped.

Thanks
