Got a Powermax 185 boiler, tested the central heating the other day and it was fine, a few days later I had to drain a radiator downstairs, then when I tested the heating it didn't come on ?
I've checked the pump, and it definitely works, as its turning inside the bleed valve. Although water is dirty. If I start draining the radiator now water doesn't get replaced in the F&E tank, so I'm thinking its one of the following problems....
* Cold feed blockage
* Big airlock in the system
* Pump blocked
I'd appreciate any opinions or help on this please.
