Intermittent DHW. No real obvious symptoms to suggest what it could be. Tried Preheat on and off.. Tried just DHW with CH off... Changed both microswitches for secondhand spares...
One thing i have noticed is that the RESET function doesn't seem to work anymore... I'm sure it used to make the boiler shut down and then restart.. Could this point to it being the PCB??
Any help greatly appreciated...
