Vaillant thermoTOP F22 fault (Hungary)

Traptor · 26 Dec 2021

Hi Guys! I have same problem with my Vaillant thermoTOP plus machine. The pressure of wather is OK (1,3 bar) but the machine is stopped per day. The fault code is F22.
I have a hot water storage (80L) wich is connected to the thermoTOP plus machine.
Have somebody an idea to what can I do?
