After switching my consumer unit off temporarily to check a switch, my boiler (oil WB Greenstar Heatslave ii combi, only a few months old) won't come back on. The LCD is blank and the wireless thermostat had a Fault A21 which just means it can't find its friend. Any ideas?
I've checked the FCU all the way to the boiler which looks fine and has power. I haven't found any obvious fuses inside the boiler which might have blown.
WB are closed until Monday so won't be any help soon. It's starting to get a wee chilly in the house so any help gratefully accepted (not to mention no hot water).
