TROUBLE SHOOTING
1. There is no display on screen after the machine has been connected to the power source:
▪
Check the overload button. If the overload protector button bounce, press this button.
▪
Make sure, the power source, overload protector, control board are connected well.
▪
Make sure, the wires from the control board to the computer board are well connected.
2. E01 display
– Failure of signal from computer board to the control board:
▪
Check the wire from the control board to the computer board, if it is not broken. Replace, if
necessary.
▪
Failure of signal transfer to computer board, electronic parts of computer board may be
damaged. Change the computer board for a new one.
3. E02 display
– Anti-explosion protect or motor problem:
▪
Make sure the wires from motor are well connected. If there is no problem with wire
connection, change the motor.
▪
Check if there is a bad smell from the motor control board. If the IGBT of control board is
damaged, replace it.
▪
Check if the voltage is right.
4. E03 display
– No signal:
▪
If the E03 appears after running of 5 to 8 seconds, this is the failure of signal. Check the
connection of a sensor. If it is not well connected, connect again. If the sensor still does
not work properly, replace it.
▪
The signal failure of control board. Replace it.
5. E04 display: The failure of incline:
▪
Check that the signal wire of incline motor is well connected.
▪
Check that the AC wire of incline motor is connected to the right slot.
▪
Check that the wire of incline motor works properly. Replace if necessary.
▪
Change the control board for a new one.
▪
If all the wires are well connected, reset the button on the control board and start it again.
6. E05 display: Overload current protection:
▪
May be the current is too strong and the system protects itself. Try to restart the machine.
▪
May be a part of the machine is locked and results in the motor stop. Add the oil to the
machine and restart it.
▪
Check if there is a bad smell coming from motor. If it is so, replace the motor.
▪
Check if there is a bad smell coming from the control board. If it is so, replace it.
7. You cannot start the machine. After you have pushed the start key, the time is counting, but
the motor cannot work and you can see no error code on the screen.
▪
Check that the wires of motor are well connected.
▪
Check that the safety pipe on the control board is not damaged. Replace if necessary.
▪
Check that the IGBT on the control board is not damaged. Replace it if necessary.
