I have a Range Powermax combi bolier system. I have come to turn the heating on for the first time since February (ish) and the boiler doesn't want to start up. It is constantly used to heat the water in the property and does so without any problems. The external thermostat has been turned up and the radiators are at their max setting. Any ideas would be much appreciated.
possibly the pump jammed after the heating being off for so long. if you can, take the nut from te front of the pump and insert a screwdriver ad try to rotate the shaft
