About every 12 - 24hrs the boiler cuts out. Leave it for about 20mins and then turn knob to off and back to CH and fires up. Try too soon and it doesn't work.
Diverter valve was replaced a couple of months ago but this fault started beginning of November. Some enquiries have pointed at the top pin not fully retracting though it clears the microswitch after 2 or 3 minutes. Pin is free moving and diaphragm all clear so don't understand why it doesn't retract. The DHW pin retracts immediately. Is this a red herring or some other underlying fault?
Otherwise for 10hrs or so the boiler works as expected, on/off as temperature is reached, hot water when needed. Pressure from 1.0bar cold to ~2.0bar when up to 60deg.
If I turn selector switch to Off and then On at other times the chances are the fault condition will display and I have to wait the 20mins before it'll kick in.
