Hi,
I have a Gerkros Woodpecker 20Kw wood pellet boiler that is not always going into standby mode when it reaches the preset temperature.

The faults I am getting are E04 (water temperature max) and sometimes E01 (boiler temp max,this happens if the boiler does not first pick up on the E04 fault).

I can manually set the temp at which it should go into standby,and sometimes it does work,and I can see the temp reading on the display so the temp probe is working (I even placed it over a lighter to see that it was giving a reading)

In the same plug in where the water temp probe is connected into the board,are connections (marked GSM) leading to what looks like a relay(rectangular,black unit),could this be the problem or might it be the board?
