JCB 320S - HYDRAULIC NOISE

[Nav man]

Looking for some help/pointers with my JCB 320s . The hydraulics started pulsating when not in use with a tapping noise. This stops when you use joystick but returns as soon as you let go. The tapping sounds like its coming from under floor but could be anywhere to be honest.

Any thoughts?

Thanks

Pump is under the floor
Is the engine labouring when its tapping?
