Main Combi 30 Elite not switching from hot water to central heating

[jonnyg]

I was wondering if i could get a bit of advice, I've got a Main 30 elite combi and it's not switch over to the central heating from the hot water and after reading a few threads on here i came to the conclusion that it could be the diverter valve so decided to get a repair kit off ebay.....
I isolated the water/electrics and drained the combi and removed the valve which did look knackered and replaced with the new one. Repressurised etc but i've still got the same fault.
I can push the pin down manually on the diverter valve which then supplies hot water to the radiators so was wondering if it could be the motor that sits on top and is there anyway of testing.

Thanks in advance Jonny
