Hi,
Our Potterton powermax HE is showing A15, ie lower pressure. When we tried to used the valves to increase the pressure the boiler won't fill up. There is no water going through, we have checked for leaks etc but cant find any and have no clue how to solve this. We have no hot water or heating. Gas and electrics are working though. Thanks
Filling loop have double non return valve when connect to system and may be stuck and not letting water to the system so you cvannot fill the system so check and if it is, than just replace it, you need to drain the water from the system
