If the juicing screw of your Philips Masticating Juicer is blocked by the ingredients, the appliance automatically reverses to unblock, beeps a few times and switches off. After this, press the ON/OFF button (located on top of the main unit of the appliance) to switch on again.

If the appliance is still blocked, then press the ON/OFF button to switch off again and unplug the appliance. After this, disassemble the squeezing system (please see the image below) and clean it before you use the appliance again.
