Hope someone can help please.
Had an engineer out in the week to replace expansion vessel on Baxi 105e combi boiler as the pressure kept dropping - we knew the expansion vessel was on the way out and had already had it pumped up once. He mounted the new vessel on the wall for easier access.
He also changed the PRV and replaced the wall thermostat, which he said wasn't communicating with the control panel.
Heating worked fine on Thursday and Friday.
Last night, heating turned itself off, water pressure had dropped again so added more (to be expected I suppose until system has balanced itself?)
Now this morning, heating didn't come on as timed, house is 9c Still had hot water though.
Checked boiler, tried resetting it several times and the pilot light just wasn't firing. This has not happened before.
In the end, I turned the dial to "hot water only" and it did fire, then quickly flicked it across to heating and hot water and now the heating has come on.
House is freezing though and will take a while to warm up and we just can't rely on it working for Christmas now.
Engineer coming back on Tuesday. Any ideas what this could be please?
I was just hoping that the system was settling after the work done on Thursday, but now I'm dreading it being unreliable again and it ruining the holiday.
