Even the trading standard approved scheme is rubbish.

Especially trustmark is useless. The vetting process verifies that the company has paid their taxes over the past three years, but does not check their work at all. My local scheme is run by an external, private company who don't employ a single engineer, and couldn't fix so much as your pilot light.

There we go then avid readers.

Once again thanks for the bits and pieces of help.
The guy is coming back next week.

I am still none the wiser as to what the problem is but have read a previous thread from here where someone stars a similar problem.

The reply was along the lines of new burner, new heat exchanger and combustion door and seals. If that is the case it's gonna be an expensive time.

Might end up taking the heateam offer of 345 for any repair if thats the reality of the matter parts alone are over 400...

Thanks

Lee

tell us what they say when they talk to you
and ask to see their flue gas analiser

did he check the co2 readings

Right, guy has been back today. Took the burner out and hoovered off any debris and bits and pieces that were in the combustion chamber. Such as, the burnt gasket crumbs.

He said there was a lot of debris at the top of the flue where the gases/heat escape to the outside world. Apparently there is a very small gap for this which he cleaned up. He tested the boiler with a gas flue analyser and the readings he said were fine.

His theory is that the dirtyness of the flue is causing trhe heat build up which burnt out the gasket. He also thinks that as a result of this the combustion door is slightly warped.

The solution i have been given is to buy a new combustion door............
Already replaced the PCB and 2 gaskets.

Does this seem like a likely solution ?
