Interesting one tonight.

Boiler worked fine this morning; heating and water. Boiler and electrics about a year old. Boiler serviced by installer on Thursday

This evening - 4pm, water came on. At 4.05pm, the Boiler spur tripped in the RCD. I flicked it back up, all okay and boiler came back on. Ten minutes later it tripped again, and even flicking the RCD switch back up has not brought back the power to the boiler.

So we've no heat. We have hot water, due to the immersion on a different spur

Anyone have an idea what the problem is? The Honeywell Drayton timer is off, the wireless Honeywell reciever for the thermostat is off. The boiler is completely off, as is the UfH thermostat in the kitchen.

I've checked the 3A fuse in the boiler on/off switch. It's not that. The motorized valves don't appear to have power to them, as fiddling with the spring valve shows they respons with a spring.

The heating engineer will come out; first thing monday. It's not that cold, and we have water, but I'm just stumped. Checked everything I can think off, and nothing - to completely wipe out that spur is odd.

Would it be in the RCD, and the trip switch isn't set up correctly? Something else?

impossible to guess without testing. you'll just have to put jumpers on till the eng. comes.
