An area technical operations manager (atom) reported that an aquabplus 2500 had a stage 1 overload protector that kept tripping in supply mode.
There was loose contact on the l2 female disconnect cable going to the motor protection switch (mps), and it was reported that this caused arcing.
It took three system resets to get the motor running.
The l2 connector needed to be tightened for the overload protector to stop tripping.
Reportedly, the insulation cracked when they tried to adjust the female disconnect.
It was reported that discoloration was also visible on the cable.
The atom covered the cracks with black insulation tape.
It was reported that the machine has been returned to service.
There was no report of patient involvement associated with the event.
