Hi please help. Just replaced a radiator. Drained off system. When i tried to restart boiler f22 dry error shows. I bled radiators downstairs ok but upstairs radiators are filling a tad only and bleeding does not complete. Please advise. Thanks

Hi Dan. I do not have a combi boiler. I have a open vented system. How do increase pressure?
 
F&e tank is full. I have opened inlet valve. When i turn on system i cannot hear anything from the pump.

Sounds like you have a blocked cold feed if your rads aren't filling up
 
You might have pulled some gunge down into the system from the f&e when you drained down... Force water using a hose on a drain point back up the system or try a wet vac.
 
Dan tnx for reply. Lucky it was not cold feed. Pump was replaced. Everything back to normal and my towel radiator had no leaks either. Tnx again
