Ecotec pro 28 s.30 no heating problem

[ryenc83]

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.

Was it working before you changed pump, what heating controls do you have.

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.

S30 not demand from external controls ur clock or stat not calling for heat,

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 ?
