Combi boiler: radiator not working but hot water ok

Mar 10, 2005 5 Replies

hi there,



i have a glow worm energy saver combi 80. as above, the hot water is working fine but the radiator is not heating up. i tried changing to different modes and bleeding the radiator but it still would not work.



can anyone please suggest what could possibly be wrong with it so i will know what to expect when an engineer looks at it. i doubt it's the pump because i hear the pump going on when the status changes to pump on.



manual can be found here:

for any help.


one rad or all of them ?

if it's all of them then I'd suspect the diverter valve is either knackered or blocked with cak from the system.

All of them. thanks for the quick reply. though i'm not too sure what a diverter valve is. is it the same as bypass valve?

well, it's a valve.

basically, it's the valve that determines which way the hot water goes

Had a similar problem... the pump was going but it's not quite right, propping it up with a block of wood seemed to help somehow, also had an electronically controll solenoid under the floor go once...
