Fuses OK
no lights on or flashing
have held start/cancel button in for 30 secs
have switched off at wall for 3 hours hoping it would reset when turned on again but still no result
on off switch iffy or more likely the main pcb power supply has failed.you need to check continuity from the plug to switch then to the pcb if they check out OK then the pcb has expired

if you are getting a power supply as far as the filter at the end of the 3 core lead you will need a meter and the ability to use it to trace the open circuit as it could be anywhere in the harness/module
