I drained down my radiators to fit new valves to them. When I try to turn the boiler backe on it won't fire up it keeps locking out even when ou push the reset button.
The boiler is a Potterton Puma.
Anyone got any ideas?
Thanks mate. Since last night the boiler (upstairs in the kitchen) now fires when I turn on the hot water downstairs. Upstairs now doesn't fire the boiler (don't even get the LED modulator and lockout now) and I've lost both hot and cold pressure on the taps (the cold I thought was direct from the mains). I get nothing when I turn on the CH . Have I wrecked the pump? And how come the mains cold has gone upstairs.
I realised I hadn't re-filled the system which I've now done so could it be the pump.
