We have to replace pcb because boiler was locking out everytime we reset and ends with f22 error after replacing pcb f22 error stopped, so replacing pcb is correct thing to do
Just spoke valliant support they said permanent rad symbol means it's ready to operate buts it's not actually heating...
That is the problem he is not responding anymore
So I have left with two option
Either I call new engineer to check pcb 24x connection
Or
Replace the divertor 2 port valve head
Which one should I try first just to keep the cost down?
Boiler had f22 error so gas engineer replaced pcb that fix the f22 error however boiler is constantly running at the background
@picasso I am not sure about 24v connection to pcb as it was replaced by gas engineer do you think this might have caused the problem ?
nothing gets warm, everything stays normal and boiler doesn't fire up its just the pump running constantly and rad symbol stays on permanently inspite of all controllers are off

Valiant echo tech plus 624 system boiler controlled by honeywell
rad symbol always on, is this normal ?
and also internal pump comes on and off automatically on its own is this normal ?
this happens when both HW & CH are both off in honeywell central heating
and HW & CH works as expected when...
