Hi there!

I have a Valliant combi heater VCW 20/1 T3 WH

Unfortunately it has recently broken down. The main fuse had gone so I replaced it and it worked fine for 24 hours! The next morning the same thing happened, no central heating/hot water, however the fuse was fine! I noticed the pressure level was right down so I brought it back up to just under 1bar. However this did not help.

Next I called out an engineer, who has looked at it and suspects the circuit board to be blown. He said I would be best to get a "Valliant Engineer" round to look at it as they would know exactly what was wrong with it and also they would be able to get hold of the parts needed easily.


Can you guys please help out at all, or give me some suggestions?!

Thanks very much!

James.

ps. I am in the Essex area! Do you know any Valliant phone numbers?!

Cold = 0.75bar to 1.5bar

Hot = Cold Pressure + 1bar variable

The new circuit board arrived at Heating Centre today, and i fitted it myself, and we now have heating/hot water! cheers for your help!


However one thing... what should the boiler pressure be at when cold and when hot????

Thanks very much, I will certainly try them!

Is this something your company could fit for me? if so at what price?!

This is my email address, jph@talktalk.net if you can help.

Thanks very much again!

Thanks but I can only repeat the above and what the engineer said i.e. he recommended I contact a Valliant agent. I am finding it difficult to get one in the Southend on Sea/Essex area!


Can anyone help please?!

Also does anyone know the price of the circuit board for my Valliant combi heater VCW 20/1 T3 WH?!


Thanks!
