As in the title, our boiler seems to be working but there's nothing displayed on the control panel at all. Does anyone know whether the main PCB is likely to be dead or is it just the front panel?? I've probed the cable linking the front panel to the PCB and a couple of the pins are showing ~4.5V so there must be something being output from the main PCB. The controls are not working at all though and it feels as if the water temp is turned up to max.
Any help?
Thanks!
