It stopped working just before I went away. Ignited, stayed lit for a split second sometimes, or not at all. Plumber coming Monday, but today, whilst in the off position ( for both water heating and radiators) it ignited of its own accord. Stayed lit for several minutes then knocked off again.
Presumably a circuit board issue then if it ignites in those circumstances? Exactly four years ago I had fitted a new Sangamo 2 channel Heating Controller and Baxi Solo2 printed circuit board.
Any ideas on what the issue might be?.....it’s 20 years old but worked perfectly the past 4 years. Thanks.
