The high pressure switch within the refrigerant circuit has been engaged. This is usually a result of low water flow to the unit or a faulty high pressure control.

The unit will show HP6 after 6 HP faults. This will stop the unit for protection.

Check water flow to the unit, clean all debris traps, and clean/backwash pool filter if necessary. If code persists, please call Heat Pump Services at: (800) 375-7378.
