I'm hoping someone here has some useful advice (that I can understand).
I have a Suprima 30 Boiler. It's coming up to seven years old.
When starting from cold it fires up, pilot light etc is on, and then there are a couple of loud bangs and it stops, the pilot light goes out. The bangs sound very much like there being air in the system.
The noise in the system started a few months ago when I had the valve in the shower replaced. Since then the shower doesn't drip and has kept it's temperature, but there was a much longer delay than before in the hot water coming through. Over time this has got worse and the shower would only start after running the hot water tap of the bath and then turning that tap off.
The pump/airing cupboard started making increasingly loud bangs and noises when it fired up. This could be stopped by manually switching the pump to position 2 rather than position 3. Dealing with the symptoms not the cause I realise but it worked. Again it sounded very much like air in the system.
I have bled all the radiators, upstairs and down, none of which had any air in and the water was clear.
In the last few days the amount of hot water/level of central heating has been decreasing and now it has stopped completely. The pump was still hot at this point, but clearly not pumping anything. I have turned it all off.
Questions are:
is there a way I can see if there is air in the boiler part, not just the radiators and fix it myself? (I'm okay at basic plumbing and electrics but nothing advanced)
Have I irreversibly damaged the pump and/or boiler by ignoring the problem?
What should I do now?
Many thanks for any advice you can give me.
