Low water flow in the unit or faulty high pressure control. Check water flow/backwash. The unit will show (HP6) after 6 HP faults. This will stop the unit for protection. Possible causes:

The filter is in backwash position.
The filter pump is stopped.
The filter is dirty.
Shortage of water to pool pump.
Water pressure switch must be adjusted or it is broken.
The unit is in the protection mode and will show (FL3); press any key to restart the unit.
