My boiler has recently struggled to kick in and had to turn off and on the hot water to get it to start but doesn't start at all now, Iv had a quick look and there is i pilot flame but the igniter keeps sparking and doesnt ignite the main burner, Iv had no experience with boilers and don't really have a clue have they work in detail, I'm thinking it could be the gas valve or thermocouple but could be completely wrong! Any help or advice of what to check etc would be great.
Many thanks
