Boiler hissing / spluttering and leaking after shower

[trillo]

Hi, I hope somebody can help me identify a problem I have with my boiler.

It's a 'Halstead Ace High' combi boiler. The central heating and hot working are fine, however after a shower or long-time use of hot water it makes a hissing / spluttering noise for about ten minutes and leaks water (brownish in colour).

If I turn the heating straight on after the shower, then this eliminates the problem, but I don't want to keep on doing that!

Any ideas about what the problem is and how much it might cost to fix?

Thanks,

Rob
