Fault Description |
Handling measures |
|
E01 |
Indicates overcurrent. |
The motor coil or circuit board is short-circuited or has water ingress. |
Replace the pump motor assembly |
|
E02 |
Indicates idling. |
Air blockage or rotation speed below the set value |
Drain or replace the pump rotor. |
|
E03 |
Indicates locked rotor. |
The rotor is jammed due to a foreign object. |
Disassemble the rotating rotor, remove external forces, and reassemble. |
|
E04 |
Indicates undervoltage |
Input voltage <170VAC |
Wait for the voltage to return to normal and resume operation automatically. |
|
E05 |
Indicates IPM overtemperature. |
IPM module damaged and broken down. |
Replace the control circuit board. |
|
E06 |
Indicates overvoltage |
Input voltage > 290VAC |
The voltage difference drops by 5% and resumes operation. |
|
E07 |
Indicates a software exception. |
The pump motor is running out of control. |
Replace the control circuit board. |
|
E08 |
Indicates phase loss. |
UVW three-phase missing |
Replace the stator coil or the control circuit board. |
