Alpha 240e wont ignite when cold

[Crescent_fiftyfive]

Hope someone may be able to help. Have an old Alpha 240e that locks out when it tries to ignite.

Engineer has looked at it. If you remove the cover from the combustion chamber it ignites every time. When the cover is put back on it wont ignite. Once ignited you can replace the cover quickly and the boiler will continue to function for HW and CH. stoping and starting as required. Once the boiler has cooled down overnight it goes back to locking out.

Any thoughts??

Did the engineer not tell you what he thought?????

common fault that the eng should easily repair

Common fault on those old girls, but to rectify the fault is for a COMPETENT serviceman. Your bloke doesn't sound as if he 's got a clue. Easy fix, but RGI required.

2 separate engineers came out. first thought it was the ignition pcb. replaced that no difference. 2nd could not explain why the boiler would ignite with the combustion chamber cover removed and not when it was replaced.

I was hoping for some suggestions from the forum??

Sorry we are not allowed to.

My suggestion would be to call another engineer. Preferably one who knows what he is doing. As previously said. This is a simple fault to diagnose

Sorry why not?

Please read this in full. Especially the bits near the end

Thanks, I wasn't planning on doing anything to the boiler myself, just trying to understand a problem. Having now had 2 engineers from different companies both Gas Safe registered I am at a loss.

Only loss you have is not paying for someone that knows what they're doing.

Halsteads were good for this one too

Usually down to crap maintenance - or lack of any maintenance at all.

Sadly inherited the boiler, so no real history of past service or maintenance.
