The pressure gauge on my boiler is hardly moving

So what's the problem? Why should it move? 0.9 Bar is Ok.

Thankyou for the reply.Its just that in the manual it says when the display flashes with the bar reading there is a prob?.

So put the pressure up to 1.0 Bar and see if it makes any difference. Won't do any harm.

Thanks once again,ill give that a go.

Lost all pressure now down to 0.3 bar fault 22 now flashing on display!.Water pressure to the boiler appears to be ok!.Central heating and hot water now not working.

So you're loosing water pressure, but where? Out the discharge pipe from the PRV (pressure relief valve), internally in boiler (e.g. AAV - auto air vent) or from system pipework (typically around spindle of radiator valves?

If you have an Ecotec it must be new (and under warranty). Best have a word with the installer!
