Got the above 4-year old combi boiler which has a built in 40 litre storage tank.
Had a radiator removed and a new towel radiator fitted by a handyman.
Boiler went on the blink after he partially drained the system to also change some pipe work in a bathroom and capped off each side of the radiator return and flow.
F1 but mainly F2 error msgs appear on the boiler LCD and once or twice an F (d) error msg appears.
I manage to get the central heating working again but the hot water seems to throw up an issue and the temp on the boiler fluctuates between 80-110 degrees but then stops working again after making some noises.
Spoke to Viessmann technical who said that it sounds like air trapped in the boiler system itself, probably heat exchanger related and I’d need a service engineer.
I should add that I’ve bled the system and even emptied it by opening the main rad drain valve and opened all radiators to ensure no trapped air.
Called my admiral home emergency policy who sent someone with what I considered to have broken English. He says he "thinks" the pump is weak. I think he’s talking rubbish. I managed to get the heating working by switching off the hot water in the config settings and it works. I then set the hot water at 30 degrees so we at least get some tepid water and the boiler does not get too hot. Anything higher and we eventually get the F2 errors again.
Any idea what this sounds like?
