Valliant VCW-SINE-18 T3WF H strange fault?

[PauloMcGuinee]

Hi all,

I have recently completed a property renovation in Northampton. Whilst doing so a heating engineer turned off our boiler and drained the system - whilst we removed radiators etc.

I have re-pressurised the system to 1 bar and it stays pressurised at that. I have turned on the power and fired her up - the pilot light is on. The boiler bubbled back into life and gives a satisfying hum. However thats all that happens the water runs cold (sometimes slighItly warmer than cold!) and the radiators and pipes never warm up.

I have had a reputable local heating guy to come and look today who spent some time on the phone to Valliant. He tells me the pump appears to run all the time unless the power is turned off. Other than that he is unable to work out the issue. He has suggested a new PCB - or to find someone who has knowledge of this boiler.

Having researched on this forum I have seen there are a couple of 'Bunny's' who know there way round a SINE-18. Are you still active here?

I'd be happy to pay someone with relevant experience to come and have a look - as mentioned we are in Northampton. Or if someone could help me fault find or offer some ideas as to what the problem could be I would have a good starting point!

Thanks guys!

Paul

He may be reputable but seems a little out of his depth with this old boiler.

I wonder why if renovating the property that you did not include a replacement for the 25 years old boiler.

There are some who post here in your county who will be pleased to help.

But Northants is quite large and your postcode would help you to find someone suitably located. I could potentially help if you were in Daventry!

Thanks for the reply, the property is in the Semilong area of Northampton. We have renovated the property on a tight budget and the boiler was functioning very well when we started the property - so the extra costs involved in a replacement would have made little financial sense. Hopefully a repair is possible - I wouldn't want to make a decision to rip out anything in the house until an expert has cast an eye over it and offered an opinion.
