I have an Ariston Genus27RFFI coupled to an unvented cylinder. The boiler has failed because the top, quick acting fuse on the right hand circuit board blows when the boiler reaches the end of its purge prior to the burner going to full burn. What should I check to test why this fuse is blowing. Its freezing here so be quick.
