Ariston Boilers Guide

Hi All,

I have an Ariston Clas HE system, it is around 5 years old and it work fine till today. I realized that radiators are cold, went to see what is wrong with the boiler and saw error message 108. Any idea what does it mean, and how to fix it fast without spending a fortune?

Hi Jack

It is a pressure system fault. You need to do following things on cold boiler:  find a braided hose under the boiler, it will have two black or grey knobs. Turn both of them the way they are facing the same way. Look at the pressure needle and fill the system to the value of almost 1.5 bar. Then put the knobs back into its previous position. Restart the boiler.
