Worcester 24i RSF - no power light

[Sizer]

Hi, we have the above combi in our static caravan, was fine last week, this week no heat or hot water.

The power light in the boiler does not come on, i have checked the trip, main fuse and 2 fuses on the PCB and all are fine. The PCB was replaced 2-3 years ago and I was wondering if anyone had any other ideas as to why it wont turn on/has no power light on.

I'm guessing the board has gone again but any help would be appreciated?

Check you have voltage going into the boiler & across the on off switch, transformer could be suspect

Check if overheat stat on top of boiler has tripped, a red button will probably have popped out.
If it keeps happening, it's likely to be heat exchanger needing replapled.

forgot about that

I thought the o/h on that one only interrupted the gas valve?
