Mend Ferroli Optimax HE 31 Boiler Error

Ferroli Optimax HE 31 - overflow pipe dripping F37?

We are having repeated F37 error with dropping pressure, having to top up at least twice a day. No leaks on rads but overflow from boiler outside dripping constantly. Would this cause the F37 problem

Hi toptrish

Yes there is a pressure gauge, but it rarely goes up above 2.5 so that sounds like an expansion relief valve.

Is there a pressure gauge? top up to 1 bar then fire boiler up, watch pressure gauge to see if it goes up to 3 bar if not and water is still dripping from overflow pipe the expansion relief valve needs replacing, If pressure goes up to 3 bar then the expansion tank requires attention
