F 75 – but a new boiler

Hi there
F 75 is displaying – however this boiler is less than 6 months old
very unhappy customer

Hi Ying,

Cannot help you with the very unhappy customer part.  But could advise you to go back to the installer and supplier of the boiler as it is probably still in warranty.  The F.75 is the most common fault with the Valiant EcoTEC Plus series.  We have a section dedicated to it in our FAQ.
