Turn the power off and then back on again.
Error occurred in the internal temperature sensor.
Step
1 Connection failure of the internal
temperature sensor harness
2 Main PCB failure

Turn the power off and then back on again.
Machine detected more than 100 times that supplied power was unstable.
< User Check >
- Turn OFF the power switch. After several seconds, turn ON the power again and check that
this error is reset.
Step
1 Low-voltage power supply PCB
failure
2 Main PCB failure
Note:
The irregular power supply detection error (Error code 0900) of the low-voltage power
supply PCB unit occurs when there is a large distortion in the power supply voltage supplied
to the machine. In this case, if the same power supply is used, the same error might occur
again even if the low-voltage power supply PCB unit is replaced.
For this reason, be sure to ask the user to rearrange the installation environment.
