E0 and E2: Malfunction of defrosting temperature sensor.
Ways: 1. Reconnect and ensure that the connection is reliable.
2. Replace the coil temperature sensor.
E1: Malfunction of the humidity sensor
Ways: 1. Reconnect and ensure that the connection is reliable.
2. Replace the humidity sensor.
E3: Phase sequence error
Ways: 1. Swap any one-phase fire line within a three-phase fire line (L line) of the power wire.
2. Check whether the power supply is out of phase, or voltage imbalance.
3. Circuit board three-phase detection line failure requires the replacement of the main control board.
E4: Malfunction of environmental temperature sensor
Ways: 1. Reconnect and ensure that the connection is reliable.
2. Replace the humidity sensor (Generally, the temperature sensor and humidity sensor are assembled together).
E5: Malfunction of system high pressure
E6: Malfunction of system low pressure
E7: Alarm for full water
Ways: 1. The water tank is not well placed, please re-place the water tank position.
2. The floating disk magnet on the water tank falls off, causing the water full tips or floating disk fracture, re-fixed small magnets or replace the floating disk.
3. Water level sensor failure, replace the water level sensor switch.
E8: Malfunction of overload current of the compressor
E9: Malfunction of overload current of the motor.
