Worcester Bosch 35CDI II - Gushing Water - Please HELP

Brighteyes · 26 Dec 2009

I just changed the diverter valve on my Worcester Bosch 35CDI II and when I tested it by putting the hot water on. The boiler came on wanting to heat the hot water then I didn't like the sound it was making so I shut the hot tap. When I went to boiler water was gushing out from underneath. I put everything back the way it should and put new O rings where possible.
I think the problem might be from where the fillinh loop assembly joins the plastic flow manifold because I can't get it to fit tight. refer to fig 40 on page 25 on the manual (link below).

I'm in Salford, Manchester. How do I use the filling loop? Is this instead of the diverter valve?

best bet is take it all out again, clean all the fittings, pipes etc and replace all o-rings, if you get stuck i can do it for you but am not cheap. it should not take you more than 1hour.

How much will you charge? I may have located the problem. I'm about to test it now.

No disrespect intended OP, but not sure this is your DIY thing when you have to ask the above.

I just couldn't think how the filling loop could help the situation thats why I asked.

I just tried running the hot water again and it not making a good sound. There's no water gushing out now. I've filled the boiler. Is there something I need to do before I run the hot water? I dont want to keep trying it incase i damage something.

whats not a good sound

leave the tap running with the boiler turned off, most likely air in the pipe work, if that does not work bleed your pump and possibly the radiators. did you drain your system.

is your air vent open

Brighteyes · 26 Dec 2009

The boiler is making a banging sound when I turn the hot tap on. The sound doesn't come on immediately. It comes on about 15seconds after I switch the tap on.

take the pump screw out and turn it manually. does the pump spin in ch mode
