The PT02 outlet pressure low issue in a BITMAIN AntSpace HK3 V2 hydro container system could be caused by the following:

1. Filter is clogged – Solution: Clean the filter element.
2. System is short of liquid (low return pressure) – Solution: Refill the system with liquid.
3. Water pump cavitation – Solution: Detect the pressure on the suction side and refill in time.
4. Pump shaft connection problem – Solution: Check the mechanical connection of the pump shaft.
5. Insufficient lubrication of motor shaft – Solution: Add lubricating oil.
6. Water pump shaft seal issue – Solution: Replace the water pump.

These checks and solutions help restore proper outlet pressure in the cooling system.
