Here is what I have tried :
Clean secondary heat exchanger (twice)
Replace overheat thermistor.
Replace PCB.
Bleed pump.
Still the DHW oscillating between hot and cold. No errors on the panel.
What else could I have missed?
A new boiler will be an option in the new year but I just need to try and nurse this one through another winter.
