Biasi Boiler Guide

Hi Folks,

I have two-years-old Biasi Riva compact HE boiler. From last few days, I am noticing that hot water is going to excessive temperature. There is also a warning in the form of fault light. After all this, the boiler goes into a lockout state. I have restarted the boiler but all in vain. Does anyone have any knowledge regarding how to fix this issue?

Looking for the suggestions

Alan

Hi Alan,

I guess you should replace a thermostatic valve & put non-return regulators on cold and hot feed to shower. You are facing this issue due to an unexpected reason i.e. cold water is going into the line of hot water via the shower. You can contact a skilled Biasi engineer for additional help.
