Vokera Mynute 20e - No Pressure, No Fill Loop

Start with the basics - power at the boiler , some sort of indicator light onthe boiler.
Water inthe system - try a radiator bleed screw to see if it squirts out.
Gas - trace from gas meter to boiler to see if valves are open. Don't open any gas valves if you find gas is turned off - get a gas safe man !

Yeah I ran the fridge, washing machine, kettle and toaster off various sockets with different fuses and they all work fine. I'd say in the end it is some electrical problem given the lack of activity with the boiler. I'm just going to get someone out to sort it, I've had enough stress moving country in a pandemic now to do me for the month and as dal5band said above, if it ends up being a gas issue it'll be even more over my head. I'll call the professionals, it'll probably be something small and stupid, they'll probably have it sorted in 5 minutes and have me pegged as an eejit.

If there's one cistern it's a deli sealed system. Like I said earlier there'll be a gate valve somewhere. They fill, them disconnect the lp switch tien the pump on to pressurised. Sometimes they reconnect the lp switch sometimes not. Get a plumber.
