What to do if PHNIX Water Pump has communication failure?
If your PHNIX Water Pump experiences communication failure between the wire controller and the main board, the likely cause is a connection issue. You should check the connection between the wire controller and the main board to resolve this.
What to do if PHNIX Water Pump shows high pressure protection?
If the PHNIX Water Pump triggers high pressure protection (HP), the HP switch might be broken. To resolve this, check or change the HP switch.
What to do if PHNIX PASRW020 shows low pressure protection?
If the PHNIX Water Pump triggers low pressure protection (LP), it might be due to a broken LP switch. You should check or change the LP switch.
Why does my PHNIX PASRW020 have antifreezing protection?
If the PHNIX Water Pump activates antifreezing protection, it's likely because the antifreezing temperature is below 2 degrees. In this case, check the flow and water system.
What causes water flow protection in PHNIX PASRW020 Water Pump?
If your PHNIX Water Pump indicates a water flow protection issue, the flow switch may be broken. You should check or change it.
How to fix water inlet temp sensor failure in PHNIX PASRW020?
If the PHNIX Water Pump reports a water inlet temperature sensor failure, the temperature sensor is likely broken. You should check or change it.
