What to do if my SolarEast Heat Pump shows E03 water flow error?
- C
  Cynthia CantrellAug 17, 2025
  To troubleshoot a SolarEast Heat Pump experiencing an E03 error (water flow switch failure or low water flow protection), follow these steps: * Ensure the pipeline valve is fully open to allow clear water flow. * Verify the water flow switch is correctly installed and the model is appropriate. * Confirm the water flow switch connection line is inserted into the correct port (D13 white). * Check that the circulating water pump is functioning normally and the water system isn't blocked. * Assess the water pump's head and flow; if insufficient, consider adding a hot water auxiliary pump. * Ensure the external auxiliary pump is not reversed.

What to do if my SolarEast BLN-018TB1 displays E06 Low voltage switch failure?
- S
  Shannon ClarkAug 22, 2025
  If your SolarEast Heat Pump is showing error code E06, indicating a low voltage switch failure, here are the steps you can take to resolve the issue: 1. Check the low-pressure pressure switch for any damage and ensure the wiring terminals are correctly connected (low voltage switch D12 blue). 2. Use a pressure gauge to connect to the low-pressure inspection port and measure if there is a refrigerant leak in the system. After supplementing the refrigerant, use foam to check for refrigerant leakage at the welding joint of the copper pipe. 3. Verify that the fan is operating normally. 4. Inspect the system for blockages by connecting a pressure gauge to both the high and low-pressure inspection ports simultaneously to measure whether the operating pressure of the system is normal.

What to do if SolarEast BLN-018TB1 Heat Pump shows E12 Exhaust temperature too high protection?
- G
  Gregory MillerAug 26, 2025
  To address an E12 error (Exhaust temperature too high protection) on your SolarEast Heat Pump: 1. Check the system for blockages or insufficient refrigerant. Use a pressure gauge to connect to the high and low pressure inspection ports to measure the operating pressure of the system. 2. Check if the exhaust gas temperature sensor is damaged. Use a multimeter to measure the resistance value (T3 red port).

What to do if my SolarEast BLN-018TB1 displays error E37?
- K
  Kevin RushAug 27, 2025
  To resolve the E37 error (Too large temperature difference between inlet and outlet water protection) on your SolarEast Heat Pump, you can take the following steps: 1. Make sure that the pipeline valve is fully open. 2. Check if the water pump is working. 3. Check the rated head of the pump and whether the rated flow meets the requirements for normal operation of the machine. 4. Manually drain the drain pump and pipe air.

What to do if SolarEast BLN-018TB1 Heat Pump shows E02 Phase loss fault?
- D
  Daniel DavisAug 30, 2025
  If your SolarEast Heat Pump displays error E02 (Phase loss fault), take these steps: 1. Ensure the power cord is securely connected. 2. Use a multimeter to check for 220V voltage between the neutral wire and each live wire while the power is on. 3. Use a multimeter to check for 380V voltage between the three live wires while the power is on. Note that 220V machines will not experience this failure.

How to fix SolarEast Heat Pump E01 wrong phase protection?
- D
  djensenSep 2, 2025
  If your SolarEast Heat Pump shows E01 (wrong phase protection) error, the solution is to exchange any two of the three live wires (R, S, T) and then power on the machine again. Note that 220V machines will not have this failure.
