I have a similar problem with this boiler. When CH on, boiler overpressurises, (check relief valve outlet) You will then lose water from the CH loop and will have to repressurise when the CH loop cools. The problem is most likely caused by a loss of air from the expansion tank, which will need re-charged. This is not a big job as it has a standard tyre type valve connection but needs an accurate pressure gauge. Probably best left for plumber.

    The unit should have a reset if misfired like something in the flue on some other type switch.

Low pressure on recently serviced Vokera 14/48se.


Identify the cold feed to the boiler, then look for a tap/service valve which when turned lets water into the boiler via a fill loop to pressurise it. 1-1.5 bar is ok

Water logged expansion tank ( ruptured diaphram in tank) or wrong size tank. This caused the excessive pressure in the system causing the relief valve to open. Also, air in the system causing flow to stop, Both conditions will cause boiler go out on safety.

Vokera linea combiboiler error code CO


It's got nothing to do with carbon monoxide. CO means the boiler is in combustion test mode, that's all (and in this case -- long since fixed, I imagine, but other people will no doubt find this page in the future -- failing). Vokera could probably have made this clearer, but hey.
