What Do We Know?

We'll get you started by identifying the most common Vaillant boiler fault codes. These are:

  • Vaillant F22 boiler fault
  • Vaillant F27 boiler fault
  • Vaillant F28&29 boiler fault
  • Vaillant F75 boiler fault

Code error F22 appears every time there's lack of water or pressure or both. This code protects your boiler by detecting that it's not firing correctly and that there's a lack of water. Another cause of this fault code could be a faulty pump. Furthermore, another issue arises if the pressure has dropped past the recommended 1.5 bar level. We know you can use the filling loop to top up the pressure, but this is only a quick fix and not a long term fix.

Vaillant F27 boiler fault has to do with the flame. This could be because the flame sensor is faulty. A broken gas valve can be a problem. Another reason for this fault could be that the PCB is not working or the boiler's ignition leads are bad.

Vaillant F28/29 boiler fault is not easily seen, but if they show up, you'll be unable to get any hot water or heating supplies. An easy diagnosis is your gas supply, but the solution is not all that simple if your other gas appliances are working properly. There could be issues with the ignition unit, ignition leads, gas valve operation or the air inlet duct.

Vaillant F75 boiler fault can be caused by a faulty central heating pump or the pressure sensor, or both. In this case, you notice that there is air in heating installation and radiators/pipework or the boiler pressure is too low. A defective water pressure pump or sensor is another symptom.

Boilers are not easy, and it is dangerous to play with gas. You can identify these problems and fix them but may not do so well.
