Potterton 24 combi hot water problem

Jonah01

Hi guys,

Have found the tap in the bathroom basin doesn't fire the boiler on to produce hot water.

All the hot taps are fine in the house and the pressure seems normal on that tap.

It's a mixer tap.

Haven't had any work done recently and with my limited knowledge think it could be the diaphragm.

Any ideas what I can try to diagnose this?

Thanks

Is it ok on other taps? If so it may be the cartridge in the mixer tap to blame.

Hi,

Other taps are fine.

If the boiler is fired up i.e the heating on then the tap will produce hot water but it won't force the boiler to start on its own.

Hopefully it's just a new tap. Would this indicate the cartridge?
