Sime Halstead combi dont stay alight

[Rincewind]

Replaced air pressure switch, but when boiler lights it goes out straight away! After six or seven attempts it stays alight, but same problem occurs when it tries to light again! Any ideas?

Faulty boiler

Blocked Venturi - when did Halstead buy Sime? Are they really THAT stupid?

 

[Rincewind]

Cheers, i'll check venturi. A lot of people agree with scatman! Just put a new boiler on costs a lot more money than a repair. Ta for the other suggestions.

I think that its a Sime boiler badged as Halstead.

There is a lot of rebadging going on!
