No noises from the fan or pump, dead as hector
The fuses have been checked and are ok so that rules them out. There is 240v at the boiler connection so the 3 amp fuse at the spur has to be ok.
The fuses on the PCB board were checked with a multi meter and all showed ok.
The plug in transformer on the PCB board has been tested remotely and is giving the correct voltage outputs.
All the wiring going to the boiler has been checked for continuity.
That only really leaves the PCB board but the supplier said it was tested before dispatch so the engineer is baffled why after all these checks are showing correct but the boiler is still dead

Ok thanks I'll tell the engineer to order another new main PCB board and see if that does the trick
How did you manage that then ? Oops sorry how did your engineer manage to test the correct voltage on a disconnected transformer ?
I didn't do the test but he said the readings were fine
It's a black transformer and there is 1 blow and 2 glass fuses.
Was told it was giving out 9.5 volts and 24 volts.
