Two common errors that can occur with Vaillant boilers are the F29 and F22 errors. The F29 error indicates a problem with the water pressure in your boiler, while the F22 error indicates a problem with the boiler’s ignition.
To fix the F29 error, you should first check the pressure gauge on your boiler. If the pressure is too low, you can increase it by opening the filling loop valve until the pressure gauge reads between 1 and 1.5 bar. If the pressure is too high, you can release some of the pressure by bleeding a radiator or opening the pressure relief valve.
If the pressure is not the problem, the F29 error may indicate a faulty pressure sensor or a leak in your boiler’s system. In this case, you should contact a qualified engineer for assistance.
