CAT 407 low steering pressure

Got a warning light coming on from cold, turns out its low steering pressure, any ideas what would cause this?

Does machine work okay? maybe just a switch failed. some machines now have accumulators on the steering circuit so might be that gone? or if its not working then maybe a pump failed or if a single pump then maybe the steering priority valve? I dont know the machine at all so i can only guess, i never really see CAT handlers. I got a local 13metre one that someone bought recently to go service sometime but thats it, never worked on any CAT newer than the TH62 and there very old now!

Hi, the machine seems to be working as normal, the buzzer seems to sound when engine is on tick over, do you think it could be oil reservoir, a little to low, there is plenty of oil in there but just under inspection glass marker?
