Drum/Roasting fan/Cooling fan inverter W6

The alarm indicates that the controller has received an excessive amount of power.

Disconnect the power cable from the machine and reconnect it. Perhaps the error will disappear after restarting.

If the alarm still appears, please check if fuse 101F1 is correctly positioned.

When the alarm is triggered, proceed to open the control panel door and examine the error codes displayed on regulators 101U1, 102U1, and 104U1.

Please provide the error code displayed on the inverter.

If the inverter on your machine lacks a display to read the error code, please refer to the following information;

To check if the problem comes from the motor or the inverter is to restart the machine and check if the alarm appears directly after restarting without having pressed any other button.
If the alarm appears immediately after the machine is restarted then it suggests that the inverter is faulty.
If, on the other hand, the alarm appears after pressing a button, then the problem could be the motor.
