Hi all,
I am in the process of adding some new rads and pipework to the upstairs of my house. In order to replace the upstairs pipework I drained down my Worcester 240 today, leaving the downstairs in place for now and removing the upstairs pipes.
Over the last few months I have drained and refilled several times to do work with no problems. But today after refilling, the boiler has decided that it doesn't want to fire-up again.
The pressure is refilled to 1.5 bar and holding steady.
I have checked the pump by loosening the screw with it running and got a fair bit of air out, but it didn't light.
I have read up about the AAV and took off the inner cover to see if the cap was screwed down. But there was no cap fitted at all.
I wondered if perhaps the AAV was stuck and not letting the air vent out. I certainly didn't hear any air coming out of it when filling the system up.
Should I try to shove something down the hole in case it's stuck. I have a feeling it will probably jam open if I do.
I'm fairly sure the fan is on as well as the pump, but not certain.
There is no pilot light or sparking noise for either the heating or the hot water.
The only problems before this was a small leak from the Diverter Valve which we have lived with for several years without it getting worse. Just a few drips several minutes after demand for HW.
Any suggestions please?
