Troubleshooting
DANGER - RISK OF BURNS AND INJURY
• Let the inside of the device cool down and avoid touching the hot surfaces.
• Before handling the inside of the device to clean or unclog jammed food items, unplug the device from the wall outlet.
Check if an object appears to be stuck in the device. Remove the food that may be too hard for the device to avoid damaging it. Avoid placing your fingers in the bucket near the blades. Instead, use an object to move it. You can then turn off the error code by pressing the start button for 3 seconds and then restart the device.
