Last night I needed some hot water quickly so switched on the immersion heater which is normally switch off. There was a loud bang. The Honeywell control unit which is attached to a fuse next to the immersion heater switch/fuse went blank and the boiler shut down. I tried changing the fuse leading to the control unit and pressed reset but just stays blank. The boiler remains lifeless. I tried turning the thermostat on the boiler on manually and can hear the quiet click but it doesn't fire up. My educated guess is there's been some sort of static build up on the immersion heater. This has caused a surge when I've switched it on. This has fried the control unit and quite possibly fuses/circuitboards on the boiler.
Anyone heard of anything like this happening before? I'm trying to get hold of my gas man but Sunday morning so a bit tricky. Got two cold kids and a wife at home!
Cheers!
