We have a Domusa MCF - DXV sealed room boiler, and yesterday on returning to the house, found that the boiler had turned itself on, rads were hot and DHW also hot. And the pressure was at almost 4 bars.
First, I turned off the boiler on/ off switch, but it stayed on anyway, so had to disconnect the power supply cables. I also saw burn stain on the plastic connector, (which I intend to replace) where neutral and ground power supply wires are connected.
Finally, I discovered a dead mouse stuck to the power supply board. I then cleaned off the power supply board (see photo), reconnected the boiler, but had the same problem of boiler staying on. Do you think a new power supply board might solve this problem? Thanks
