Does water come out the kitchen hot tap?

Yes water comes out of the hot kitchen sink tap.. but it's not hot, and the boiler does nothing either

More than likely the diaphragm in divertor valve is worn and needs teplacing .Not a nice job

Got one on the shelf gathering dust.

Fitted it to boiler and before finishing putting cover back on the owner came in pi55ed as a newt, fell on to control panel/pcb ect which inturn fell in to bucket of water. Ripped the wiring to bits.
Phoned his dad, who was not too impressed.

Fitted replacement boiler, so still have parts if anyone needs them

ps Pain in the arse to fit

So why would it work on one tap but not others?

the kitchen tap is probably the last one on the run, the further the outlet is from the boiler the more pressure there is on the diaphragm and as it wears it will work on the closest but not the furthest.
