Central Heating

[PAULBROM]

Hello all need some help if poss please.

I replaced the three way valve on the heating system all went well, water back in the rads and bled.
Motorised head unit working ok .
When i switched the Heating back on the boiler isn't firing up for either water only or CH and water
The pilot light is on
All devices are calling for heat
The pump is working

I have just done a reset on the boiler and no change.
pilot light is still on
Any advice greatly appreciated

What boiler/system do you have?

 

[PAULBROM]

The boiler is a glowworm ultimate.
As regards system not sure what you mean

You could call this the $6M dollar question.
