Have had an Intergas SB30 installed since march 2013. During this very cold period, yesterday morning the boiler cut out. What was happening was the Operating Code showed 4 for
a short time dropping down to 3, repeating this several times then cutting out, the Temperature
Display showing 4. Turned off the boiler and reset the program to come on at 16.00 which it did and worked OK until 22.00 at which time it went through the fault cycle again.
Today its doing the same thing. According to the book 4 is 'No flame signal'.
Can you advise what the problem might be and how to put it right.
