E53 the dielectric temperature has exceeded 50C, erosion stopped

Hi guys
Any help would be great. I keep getting the above error on an agie elox mondo 3 EDM machine as soon as cycle start in initiated.

Anyone have any idea how to rectify this. We bought the machine second hand here and it has been happening since it arrived.

How the dielectric chill on this machine ?
Does water coolant circuit flow?
Or does the cooler work?
Does electro-valves opened?
