Glowworm Flexicom 30hx - Water/Condense in gas valve?

[Anders0n]

Anyone known of this to happen?

Called to a breakdown the other day and found water/condense (Could be either) in the gas valve which was obviously stopping the boiler working.

Took the valve off and emptied it and the boiler was working fine.

Customer comes back off holiday a week later and the boiler won't work again, same problem, even though the boiler hasn't been run for a week.

Ive checked the condense pipe and trap and it's perfectly clear.

Anyone have any ideas what's causing this?

Is there anyway water could be getting into the air intake baffle? Is it on a vertical or horizontal flue?

 

[Anders0n]

It has the standard horizontal flue.

From the design of the intake inside it doesn't look possible for water to get in that way.

 

[diamondgas]

For moisture to get anywhere near the gas valve it'll have enter via there you'd assume ... ? Certainly sounds like a strange fault ... There's been a great deal of rain about recently, any way this could be a contributing factor?

main heat exchanger leaking?

A boiler was making a funny sound from the flue, what was happening that the condense was plumbed into the kitchen washine machines waste +1.5 bowl kitchen sink and also a dishwasher, the kitchen fitter made such a bad job of the plumbing it created a massive trap in the pipework. I cant remember the boier (some time ago) but this on didnt have a cut out if the condense trap starts backing up. Try checking this out aswell, aqgree with diaamondgas aswell about the weather hope this helps

i mean backing up into combustion chamber

I had a flexicom making droning noises today, first checked the condensate that was fine. Set the CO2 max and min and they were way out. Minimum couldn't get in spec so will be back to that job, suspect faulty fan
