Hi, had local plumber have a look who diagnosed diaphragm issue and replaced (£200 inc labour). This seemed to resolve only for a short time but then started to kick in on it's own again, also developed leaks after fitting!! called back out twice and after attempts to 'tweak' leaking joints finally gave up and with help of father in law, retired plumber replaced leaking isolating valve and fill up loop (apparently should be removed after used to fill / top up system)
Now have to switch to hot water only (far left switch) and run hot water slowly in order for the water to heat up. The switch seems to move in and out when tap is opened. Let us know how you get on
