GlowWorm Ulitmate Clicking

[Tristy]

I have a glowworm ultimate boiler. Must be about 9yrs old.

Sometimes when I turn it on it just clicks away for maybe 10min before it ignites. Earlier it ingited and it was like stalling and had to light up again. I could see the blue flame go off.

The clicking comes from the module with min-max control on it. (Pic attached)

What could be wrong?

Thanks

It sounds like it needs a good service to be honest

Common fault on that boiler and easily rectified, but it needs a professional.

Looks like a gas valve problem.

Looks like it's been misdiagnosed
Just get a professional in to fix what is a really common fault, and a service before Winter. I don't give prices.
