Strange boiler behaviour

[Ames512]

Hi there,

I have an Alpha HE25 boiler which has started leaking when running.

I have powered off, removed room seal and found the lower tray full of water. I have cleaned all of this away and run the boiler. There is no leak.

I then refitted the room cover and run the heating for another ten mins. I removed the cover and the leak was back….

So it seems the leak stops when the cover is removed. And leaks when the cover is in place!

Any thoughts or ideas welcome on this !

Thank you so much
Amy

Could be a couple of things, but removing the room seal cover is dangerous if you’re not able to test for correct operation afterwards. Get a decent gas safe registered engineer to take a look, as it could even be on the flue.

Anything behind that cover is Gas Safe territory, advice on such stuff is not permitted on here.
Stuff you can do- keep an eye on system pressure (if it isn't a pressurised system then tie the ballvalve on the f & e tank up and see if the level drops over time). If pressure is steady/tank level doesn't move then you need GSR to sort it.

Thank you for replies. Understood about the gas safe thing - I wouldn’t open the combustion chamber. I have cleaned the condensate tank. I’m thinking that with the room seal in place the leak is condensing on the metalwork. But when it’s removed is condensing into the air. I will call a gas safe plumber and get them to take a look. The boiler is old so it may be time for a new one….

Think it was the way you have worded it then. If you look at the attached, the room seal removed, I should access to the combustion chamber/gas side of working on the appliance
