Hello everyone!
Wondering if someone here can help.
Just powerflushed a heating system and the boiler no longer fires up.
When demand is on I can hear the pump start, I can also feel a short burst of air come out of the flue. After this everything stops and cycle restarts. This keeps happening, although very occasionally the boiler will ignite and stay lit for a few seconds. What could be causing this?

Thanks for any advice.
 
No error codes, green power light flashes steady. Lock out light does not come on. The issue was there occasionally prior to flush too.
 
What happens when you try to run either? Do you get the C or D letters at all?
 
Apologies, thinking of a different model. What led sequence(s) do you have?
