Hello, I’m in need of some help/advice from someone who knows their salt....thanks in advance for anyone that can help me.
I recently bought a house which came with a Worcester greenstar zwb 7-25 combi boiler. I don’t know how old the boiler is or when it was installed as the previous owner “can’t remember”
The inspection that was done prior to us moving in flagged up that the expansion vessel has failed and will need replacing, so I put it on the long list of things to do. A few days ago I started getting high pressure problems with the boiler as well a lot of water from the overflow and then losing heat from the radiators until they were Luke warm at best.
So I bought a new vessel and had a plumber round to fit it last night, afterwards the rads were still not getting hot and then on top of that I then wasn’t getting any hot water! I left the heating on and tried bleeding a few rads but was just water coming out so there didn’t seem to be any air trapped in there.
Then I checked the boiler again and it had gone into error 9 So have turned it off now.
I’ve since contacted the plumber and he advised it is probably a blocked pump and/or valves.
Does this sound like the issue or am I looking at something worse? What would be a ballpark figure for draining and cleaning the whole pump and system?
Thanks for your time and apologies for the long winded post.
