    What to do if my Arden BLN-018TC3 Heat Pump displays E03 error related to water flow?
    • P
      pgonzalezAug 19, 2025
      If your Arden Heat Pump shows an E03 error, indicating a water flow issue, take these steps: First, ensure the pipeline valve is fully open to allow clear water flow. Next, check if the water flow switch is correctly installed and is the right model. Also, verify that the connection line of the water flow switch is correctly inserted into port D13 (white). Then, check if the circulating water pump is functioning normally and that the water system isn't blocked. After that, inspect the water pump's head and flow to ensure they're sufficient; if not, consider adding a hot water auxiliary pump. Finally, check whether any external auxiliary pump is working in reverse.

    How to troubleshoot E05 High voltage switch failure in Arden BLN-018TC3 Heat Pump?
    • L
      Linda YoungAug 21, 2025
      To troubleshoot the E05 error on your Arden Heat Pump, follow these steps: First, check the high-pressure pressure switch for damage and ensure the wiring terminals are correctly connected to the D11 (red) port. Then, use a pressure gauge connected to the low-pressure inspection port to measure the amount of refrigerant in the system. Next, check the system for blockages or air. Use a pressure gauge to connect the high and low pressure inspection ports simultaneously to measure the system's operating pressure. After that, verify that the fan and water pump are operating normally and that the unit's water flow is normal. Lastly, inspect the water side heat exchanger for fouling; if severe, clean it with oxalic acid and citric acid, or install a cold water pre-filter.

    What should I do if my Arden Heat Pump shows an E06 Low voltage switch failure?
    • J
      Jonathan ScottAug 23, 2025
      If your Arden Heat Pump displays an E06 error, follow these steps: First, check the low-pressure pressure switch for damage and verify the wiring terminals are correctly connected to the D12 (blue) port. Then, use a pressure gauge to check for refrigerant loss at the low-pressure inspection port. If needed, add refrigerant and check for leaks at copper pipe welding joints using foam. Next, ensure the fan is working correctly and check the system for blockages. Use a pressure gauge to connect to both high and low pressure inspection ports to measure the system's operating pressure.

    How do I fix an E12 error (Exhaust temperature too high) on my Arden BLN-018TC3?
    • K
      Kevin DavisAug 26, 2025
      To address an E12 error on your Arden Heat Pump, start by checking the system for blockages or insufficient refrigerant. Use a pressure gauge to connect to both high and low pressure inspection ports to assess the system's operating pressure. Also, inspect the exhaust gas temperature sensor for damage and use a multimeter to confirm that its resistance value is correct at the T3 (red) port.

    What does E37 error mean on my Arden BLN-018TC3 and how do I fix it?
    • E
      Erika RomeroAug 28, 2025
      If your Arden Heat Pump displays an E37 error, indicating a large temperature difference between inlet and outlet water, follow these steps: First, ensure the pipeline valve is fully open. Next, check if the water pump is working correctly. Then, verify that the pump's rated head and flow meet the machine's operational requirements. Finally, manually drain the drain pump and any air in the pipe.

    Why is my Arden Heat Pump showing an E02 Phase loss fault?
    • M
      Max CarrAug 30, 2025
      If your Arden Heat Pump is showing an E02 error, follow these steps: First, check that the power cord is securely connected. Then, use a multimeter to measure whether there is 220V voltage between the neutral wire and each live wire (this should be measured while the power is on). Finally, use a multimeter to measure whether there is 380V voltage between the three live wires (also measured under power-on state). Note that 220V machines will not have this failure.

    What to do if my Arden BLN-018TC3 Heat Pump shows E14 Hot water tank temperature failure?
    • S
      Scott RuizSep 1, 2025
      If your Arden Heat Pump displays the E14 error, it indicates a hot water tank temperature sensor failure. This could be due to: 1) an open or disconnected sensor connection line, 2) a damaged sensor, or 3) a damaged motherboard port. You can use a multimeter to measure whether the resistance is correct at the T16 (blue) port.

    What does E15 error mean on my Arden BLN-018TC3 Heat Pump?
    • T
      Terry CobbSep 3, 2025
      If your Arden Heat Pump shows an E15 error, it indicates a failure with the inlet water temperature sensor. Possible causes include: 1) an open or disconnected sensor connection line, 2) a damaged sensor, or 3) a damaged motherboard port. Use a multimeter to check if the resistance is correct at the T8 (white) port.

    How do I resolve an E09 Communication failure between the wire controller and the main board on my Arden Heat Pump?
    • R
      Rhonda GarnerSep 5, 2025
      To resolve an E09 error on your Arden Heat Pump, first check whether the communication between the wire controller and the main board is normal. Then, use a multimeter to measure whether the voltage output of the motherboard port (white port) is normal.

    What does E16 Coil sensor failure mean on Arden Heat Pump?
    • D
      Diana HardingSep 8, 2025
      If your Arden Heat Pump displays the E16 error, it means there is a coil sensor failure. This may be due to: 1) the sensor connection line being open or disconnected, 2) the sensor being damaged, or 3) the motherboard port being damaged. Use a multimeter to measure whether the resistance value is correct at the TI (red) port.
