Can anyone help?
I have an Ariston 30 MFFI Combi Boiler. When demanding hot water, it is always scalding, irrespective of the temperature setting. I guess the only time the flame is cut off, is when the overtemperature circuit triggered.
The thermistors and the power PCB has recently been changed, so suspect the control PCB, anybody have other ideas?
