DM will know that when he gets back on.

Pressure looks high though.

Mr. W.
take off the bottom grey panel and look underneath the combustion chamber there will be a data plate there which will say either vcw242 or 282
will also be a 7 figure number that starts 47 ### ## this is the GC number

As Namsag says its a VCW 242 or VCW 282. From the colour of the fascia plate and the type of combustion chamber cover I'd say 1994/95.

God I'm sad :LOL:
Hi, thankjs for your replies, does anyone know where to download the manual, I have searched everywhere, I have a hot water problem with this boiler, it runs fine for around 10 mins and then goes cold for some reason, although if you wait another 10 mins, it will actually pick up heat again, not good for a shower though! are the any parts prone to clogging up inside the boiler, I am not expecting the DHW heat exchanger as it will provide hot water for over 10 mins at a time, however, maybe the temp sensor may have scaled up?
I would guess that its a gas/combustion problem but we are not able to give DIY repair advice on that.

So you may need a gas registered engineer.

Probably a blocked HX have come across same problem on this vcw before and it was blocked HX
Yes, the cycle time is around 7, 8-10 mins, bit strange really, but when it goes cold its freezing!, your quite welcome to tell me about the combustion details, only its technically illegal for me to act on your information.

on another note, if it was the heat exchanger ( HX ) wouldnt it just go back and forth from hot to cold, or just stay luke warm? Its strange how it will actually keep its heat for nearly 10 mins, and then drop to freezing.

this may not be a problem for some if you have a quick shower, but there are women in the house who dont like it!

also, the instruction manual has been lost, and I cant find a link to download one, anyone know of a site or a link to get it?
Hi, I have made you as a friend and sent you a message? did you recieve it?
