Why the Led or LCD screen doesn’t work?

Maybe the buttons are blocked by stickers, or the screws on the back of the display board are tightened too much, so the buttons are blocked. Please try loosening the screws a little, especially the one near the function buttons. This will allow the function buttons to work properly, and then you can switch between slush mode and juice mode.

* Loosen the three screws.
*Please restore the machine to factory settings.
