Hi all,

After replacing the water pump in my boiler I have hot water but no heating.
Status shows code s.30 although there is a demand for heating. Any ideas?

Thanks in advance.

Yes it was working before the pump was changed and I have a timer in the kitchen which I use to turn on the demand.

externall controls should provide 230V to contact 4 on pcb if you have this it sounds like you fried the pcb with water when changing the pump
 
Why did you change the pump?

Have you measured for 230v on 4 ?
