Worcester high flow 440 fault

[daveaspy]

My boiler has gone on the blink! The power light next to the boiler on/off switch comes on, and the timer built into the boiler panel has power, but there are no other signs of life - no red lights, nothing on the two digit display etc.

I've checked the two fuses (ok) I can see but think there is another one inside that needs some dismantling to get to. Any thoughts on what's wrong, PCB bust? I'm waiting on my insurance home emergency cover to call me back but they are currently "very busy"

Ha, my emergency gas man from the insurers has arrived..." Oh, this is not a common boiler". Great, he hasn't a clue. Looked, prodded, "probably the PCB". Changed the fuses that I had tested and now gone, guess I'll see him in a week with a new PCB
