boiler wont come on with the heating?

Hi Juniper.
I had a similar problem with my wocester bosch combi, but traced it down to the water divertor valve.
I didnt have to take the whole valve out, just the solenoid coil which was open circuit and hence not working. I found a replacement on the internet and now heating is working fine

Depends on type of system
If gravity suspect pump
If pump primary mid position motor suspect motor
