Combi boiler hot water issue

[markw508]

I have a combi boiler. I'm having an issue with hot water - if I turn on the hot water tap, I immediately hear the boiler come on and water heat up (so far so good!) - however, when the water reaches a certain temperature, I hear the boiler turn off again, and then the water immediately starts running cold for about a minute, and then it repeats (boiler comes on, starts to get warm again, boiler cuts out).

This is really frustrating - having a shower is a constant dance of quickly standing under the water for the 20 seconds or so that it's hot, then moving it away for a while until it gets warm again.

Does anyone have any idea what might be the issue?

Yes, I know what the problem is but it's something you'll need a Gas Safe registered engineer to deal with, it's not a DIY job sadly.

Post your details here: [DLMURL="http://www.ukplumbersforums.co.uk/im-looking-plumber-gas-engineer/"]I'm looking for a Plumber or Gas Engineer[/DLMURL] and one of our lovely lads or lasses will be able to help, I'm sure!

Can you tell me the gist of what the issue is, just for the sake of my own interest?

As mentioned, you need a Gas Safe Registered Engineer to fix that issue, thanks
