Mick, you were right the error message has gone but still no heat to rads. Hot water is ok and underfloor heating on separate circuit seems fine. Could there be a motorised valve that is failing to open after being switched off all summer? If so is there some way over over riding it as a test?

I have a worcester bosh 30cdi. The hot water is working but not the central heating. The batteries in the remote thermostat are good and the receiver is getting a signal. Pressure in the system is ok. I am seeing an error -I I- flashing in the display on the control panel. Does anyone know what...
