There is no response when the glass tapping machine moves back and forth.

The reasons why the glass loading machine does not respond when moving forward and backward are as follows:

1. Check whether the power supply is normal, whether the docking station is connected with the power cord and whether the power switch is turned on.

2. Check whether the control panel is normal, whether the buttons on the control panel are damaged, and whether the lines are short-circuited or disconnected.

3, check whether the motor is normal, whether the motor is damaged, whether the motor contact is good, whether the motor circuit is short-circuited or disconnected.
