Hi everyone, my next predicament. I've got a Main Combi ECO 25 - no CH, DHW works fine.

I've just replaced the Motor valve - no luck!

Next the whole 3-way Diverter valve? Is not that then what else?

There is no room stat attached.

Any advice is much appreciated.

time clock? has to be electrical,have you looped it,if so and motor changed pcb is the only bit in between
 
So there's no time controls??? Does the boiler just work off the boiler stat/mode switch?
 
Yep, it's in an Out house - turned on when required via the heating and hot water controls.
 
If the controls are seperate, which i imagine they would be, and in the house? Best thing to do would be put a link in between the 2 external control wires in the boiler, they are next to the mains in on the connector block. Im sure it is labeled inside the boiler
 
Try link the call for heat,

if pump runs but still no luck then my guess would be a blockage?

If pump doesn't run then PCB
