Potterton Suprima 40 + EP2002. Boiler Only turns on for HW

[clownferret]

Hi,
I'm a newbie he so be gentle.
If i turn on hot water on ep2002 boiler fires up no problem, but if I turn on central heating nothing happens, and if i press the reset button on the boiler again nothing, as if the boiler is not receiving a call for heat.
FYI I replaced the EP2002 about 7 years ago.
Is this a fault with the EP2002? I have read about 3 valve motor problems also that seem to cause a similar fault.

Either the synchron motors had it or the valve is stuck in hot water only.
Very common as the valve has been in the same position for a long time.

i manually moved the switch on the motor, and this fixed the problem, however not sure if the motor is faulty. Is this something I could replace myself or is it a job for a professional?

What's the make of valve? On some you can replace the motor.

it's a honeywell, don't know the model. I'll confirm later, it's only a 15 year old house so it will be a fairy new model. (silver box with switch underneath)
