Hi all, I have a problem with my Halstead ace boiler. When either CH or DHW is requested, CH or DHW demand L.E.D lights and the burners come on but after a few seconds,minutes, half hour (time varies) both the burner and demand L.E.D drop out and boiler stops, and cycle keeps repeating itself.
I have had a new fan fitted (cured problem for a bout 3 days then started again). I have had a new PSW fitted to the fan, and the venturi has been blown out but not chemicaly cleaned (again cured problem for about a day and same started again). Have noticed that when the covers are off problem seems to go away, but obviously it is only being run for a small amount of time without covers on. I am an instrument technician so understand how things work but not being corgi registered I leave the work to my plumber, but he seems a bit stumped. Any suggestions?
Thanks
