Combi Boiler : Not enough flow to trigger hot water from tap?

[MarkeR]

Hi Guys
Bought one of these
https://www.amazon.co.uk/gp/product/B07Y32V2ZC/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1
to fit on my kitchen tap. My hot water runs perfect with just the tap as normal, when I fit this, there isn't enough flow to kick th ecombi boler into action and turn the hot water on.

Is there anything I can do?

Thanks

You would have to check the service manual for your boiler. Some can be adjusted, but there's a minimum set to stop the water boiling, as the boiler will have a minimum heat output that needs to be overcome by the flow of water.

The flow of water is reduced to much so the boiler doesn't engage.

Make sure all valves to the taps are fully open.
