I have just removed 2 radiators and drained my whole system. I refilled the system with the radiators off to the required pressure levels on the boiler. I still have 4 rads connected to the system.
The Vaillant Combi boiler now does not ignight in both Hot Water or Central Heating mode. Is this something to do with the Rads being off or do I need to repressurize the expansion vessel?
Help!!!!
