Hi folks,
I've got a Glow Worm 30hxi. I lately moved a radiator in the system requiring a drain down of the system. Unfortunately on refilling I keep getting an F9 fault. I've spoke to Glow Worm who weren't very helpful, saying it's a global error code and could mean anything! I thought it was air in the system but I've bled the pump, rads and air vents and all air seems to have been removed.
I have experienced the following:
If I set the programmer to heating only the pump turns on but the boiler doesn't seem to fire (the temperature on the boiler display remains static and pipes remain cold). When I change this to heating and hot water the boiler fires but after about 2 seconds the error code F9 appears on the LCD.
I've tried turning off the boiler for a minute before turning it on again, no luck!!! The technical guy at Glow Worm wasn't very helpful and only suggested that the overheat thermostat might need resetting. Is this likely, if so can I do this myself? If there may be other reasons for my problems could you offer an idea as to what they might be?
Many thanks,
Bill
