Has your gsr engineer spoke to the manufacture?

we dont give technical advise to non Gas Safe engineers, maybe you could find an engineer on the forum who lives in your area who could sort it for you?

welcome to the forum.

504 is not in my experience been a boiler issue, usually components on the boiler failing show a 501 fault, the cause of 504 is identified by basic gas checks, I would stop spending money till your engineer has a talk with ariston technical
