I have to keep resetting the boiler then the hot water works again for a while until I have to reset again!

If the switch isn't getting operated you'd get no hot water unless you have the CH on, which is what you've got.
If the DV/switch was sticking in HW position, I wouldn't be surprised if the boiler overheated.
So intermittent "mucking about" could all come down to the DV.
When the hw is turned on the pin should come right out smartly and press the switch fully, and go back equally smartly when the tap goes off.
The switch contacts should make clean open/closed circuits.
Quick to check if you know how - otherwise you need an engineer.
O.k. Many many thanks for your help/advise ill try and check the pin operation, might try and change the diverter valve tonight if I get stuck, ill have to call the gorgi guy back!
Many thanks everyone!
