Combi Boiler not clicking off after hot water use.
Discussion
As in the title really.
It's a Baxi Instant 105e, and after you have turned the hot water tap, bath, bathroom or kitchen sink, it doesn't turn itself off or switch back to central heating if the heating is on. You have to waggle the cold tap on and off a few times for the boiler to realise that the hot tap has been switched off.
Any ideas.

Possibly the diaphragm in the diverter valve.
If you drop the front control panel cover down, on the left hand side you'll see a brass diverter valve with a microswitch on the front of it.
A plunger should pop out and press the switch when the hot tap is open. Check to see if it retracts when the tap is turned off.
They are cheap and easy to replace and are a common fault, although I've not heard of it sticking open, they usually refuse to open altogether.
