Mend Saunier Duval Thelia SB 23 Boiler Gas Flame

Saunier Duval Thelia SB 23 - pilot won't light or stay lit?

The pilot will light with a match but there is no 'spark' and if lit with a match , the flame dies when the 'ON' button is released. The fan runs - at slow speed, while button held in

there is a problem with the igntion system, electrode etc, and also maybe a thermocouple fault, failing that it's a new gas valve, eitherway you should get the serviceman out
