Hi,
I have a Vaillant Turbomax Plus 828E combination boiler installed at the
beginning of 2000.

Around October 2002 it started developing the problem with the diverter
valve mentioned number of times on this group (hot water not working while
heating on). We had the valve replaced but then we started hearing some loud
noises (bangs!!!) coming from the boiler when opening hot water taps. You
could here the bangs all around the house through radiators. We then had the
valve replaced another 2 times by the same company (free of charge) with no
result.

Last week we decided to call in somebody else. The engineer explained that
the valve was blocking itself and that was what was causing the noise. He
said that there was a general problem with the valves for this modeland
therefore replacing it might not solve the problem (he suggested replacing
the whole boiler)

We did have the valve replaced again (£300) and the bangs are still there.
Apparently, Vaillant Technical Support told the guy that they would
reimburse us for that work as there is a general problem with this model. We
will now try and do that.

Questions for you:
* has anybody else seen this problem? has it been resolved? how?
* has anybody tried claiming refunds from Vaillant?
* how to fix this?

Regards,
Marcin Konopka

The next stage of the story:

I sent a complaint letter to Vaillant (as they advised the engineers
to exchange the valve) asking them to refund the costs. No answer to
that as yet.

In the meantime I also called in Vaillant engineer to look at the
problem. It took the guy 5 min. to conclude that the problem is to do
with the electric board "not being synchronised". He replaced the
board and everything is fine now.

On the positive note, when we explained to them that we had just paid
£300 for a valve, Vaillant charged us "only" £95 laboar and gave is
the board free (normally they would charge about £150 + VAT).

Still hope to get some more refund in response to my letter...

I hope this would help someone in similar situation.
