[traceywilcock]

PLEASE HELP...my boiler is showing up h5 code does anyone know what it is i have just purchased a pcb board which i have now fitted but it is still coming up with the h5 code please help my kids are freezing thanks, in advance

h5 is a code that tells consumers not to buy pcb -£150 ,but to call the local gsr plumber to fix it ,and would have been cheaper

i think h5 is jumper links not incorrect position or not in at all,when fitting the new pcb take out the jumper from the old pcb and put them into the new board inthe same order
