How do I know if my expansion vessel is faulty?
If you have a faulty pressure vessel then it won’t be able to take the pressure rise when the boiler is on. The key indicator is that the pressure gauge will rise to 3 bar or above which will cause the pressure relief valve to open, you may notice water trickling from the pipe out side.
Should there be water in expansion vessel?
If water comes out of the valve you have a definite expansion vessel fault. In this case the vessel has definitely failed and must be replaced. If no water comes out but no air either, you have an expansion vessel fault but the diaphragm may still be intact and it may be possible to re-pressurise.

Why is my expansion vessel full of water?

How do I relight my Baxi boiler?
To reset the boiler, turn the selector switch to the R (Reset) position. Hold for at least 5 seconds and release. The fault code will be replaced with the boiler’s current temperature. At this point on a neon indicator boiler model, the flame failure light will stop flashing and will be replaced with the burner light.
Can you replace an expansion vessel on a Baxi 105E?
Click to expand… You can replace it with an external but you will lose your preheat. I’m almost certain the mi’s say not to so I’m surprised a manufacturer does it. Assumung it’s a 105e then the manual tells you that you will have to remove the boiler from the wall to replace the expansion vessel.
What should water pressure be in expansion vessel?
When the water is heated and it expands the rise in pressure will be about 1 bar so you’re going from 1.5 bar to 2.5 bar. Why not try setting water pressure to 1 bar then there’s less chance of opening the PRV. If pressure is lost then there is a leak.
