No hot water from kitchen tap only

[Monkey789]

We have a combi boiler. The kitchen tap has been in for about 3 years from when a new kitchen was fitted with no issues. More recently, the kitchen tap (both hot and cold) seems to be spraying more than the nice flow we had before and I assumed this was because we live in a hard water area and probably clogged with limescale. I’ve removed the spout bit and rinsed it in vinegar and limescale remover but it hasn’t really effected the spraying or made it better.

Anyway now (I assume this is linked to the above), the kitchen tap won’t get any hot water. The boiler won’t fire up when the hot tap is on but it will for all other taps in the house. If the hot tap in the bathroom runs, then hot water will flow from the kitchen until it runs out and it turns to cold again as the bathroom tap has been turned off.

Is this likely to be linked with the limescale/spraying tap issue and should I just get a whole new tap? Or could it be a more simple fix?

Thanks in advance.

Combi boilers are triggered to start heating by an internal flow sensor.

It sounds like your kitchen tap is blocked up a bit, so when you turn it on, it does not produce sufficient flow for the combi to sense the demand.

Ok thanks, makes sense.

Is there a way to sort it or am I looking at a new tap?

If all other taps are fine and you have descaled then I’d say new tap.

Check the supply pipes to the tap , particularly if Flexi hose tap tails have been used ,which may be bent/ twisted restricting flow.
If isolation valves are fitted to the taps supply pipes ,are they fully open ?

To get some better advice:

Add a pic showing the spray happening from the tap.

Add a clear pic of the tap.

Add a clear pic of the pipework and connections running to the tap.

Is it a Quarter Turn tap? If so, may just need a new Cartridge. Type with a Washer, (several turns to fully open), then might just need a strip down of the internals, a bit of grease on the threads and reassemble. New Tap is a bit overkill without checking it can be repaired first.
