If the display on your machine continuously switches between programs, making it difficult to operate, and the function buttons "play disco" by lighting up alternately, please check your power supply. This phenomenon can occur in rare cases when the machine is not connected to mains power but is instead running through an inverter, and the inverter is providing insufficient voltage, insufficient power, or a dirty sine wave in the alternating current. If you test the machine by connecting it directly to mains power, it will operate normally. In this case, have your inverter checked, as this behavior indicates inadequate power or a defect.
SOLUTION:
- Unplug the machine from the power supply and wait for about 15 seconds.
- Plug the machine back in and see if the issue persists.
- Check power supply and also if the control panel is clean and dry. Sometimes moisture or dirt can cause malfunction
