Hi guys.
Just replaced a radiator in my bathroom and now my Powermax 155x won't fire up for central heating. Hot water works ok, but the only thing I did to the boiler was drain down, re-presurise the expansion vessel and refill the system.
It appears that the upper left pump in the photo is humming and getting hot. It has power to the terminals when the boiler calls for central heating. Could I have upset it by draining it down?
