No hot water & central heating - Sime Super 90 combi boiler?
Combination boiler is 9 years old, no hot water or central heating. When hot tap turned on switch clicks but pilot light & burner do not ignite, when CH put on same fault occurs. Intermittent fault,will be OK for a day & then not work for a couple of days. Diverter valve changed 3 years ago for similar fault, could it be faulty diverter valve or something else.
similar fault experienced on my Sime boiler ,it turned out to be the pressure switch on the vent fan circuit .I obtained a new switch from boiler shop chesterfield,fitted it myself & all seem's OK
