How do I clean my unit?

All parts, except the motor base, are dishwasher safe. If hand-washing, wash all removable parts in warm soapy water immediately after each use. Use the included cleaning brush to clean hard-to-reach places, and remove excess residue. Use the end of the cleaning brush to clear any buildup left over after juicing from the pulp spout and filter mesh. Use the bristle side of the cleaning brush to clean the auger and body of the filter. To clean the motor base, unplug and wipe with a clean, damp cloth. NOTE: DO NOT add water to the feed chute while the unit is operating to clean the unit.

Nothing happened when I pressed the REVERSE button.

Ensure that you press and HOLD the REVERSE button. While pressing and holding REVERSE, there will be a beep and a brief pause (3-5 secs), then the auger will rotate in the opposite direction. Release REVERSE to stop. Repeat as needed. Press START/STOP to resume normal operation.

The unit stopped working and is beeping.

The unit was overloaded with ingredients. Wait 2 minutes, then press START/STOP to resume juicing.

How do I prep my ingredients?

For best results, cut ingreidents in 2-inch pieces. Always use the freshest and ripest fruits and vegetables and wash them prior to juicing. When juicing fruits with large pits or seeds, be sure to remove the pit prior to juicing. For example when using cherries and plums, the seeds and pits need to be taken out and cannot be processed. See the Juicing 101 Chart in the IG or QSG for other helpful prep tips.

Can I juice frozen fruits and vegetables or add ice?

No, do not use frozen fruit, frozen vegetables, or ice with this unit.

Are all parts dishwasher safe?

All parts are dishwasher safe, EXCEPT the motor base.

Why isn't juice dripping from the unit?

Ensure the anti-drip lever is open before juicing. Close after juicing to prevent dripping on the unit/counter. You can expect 1 lb. of produce to yield approximately 8 oz. of juice. Yield may vary depending on produce and seasonality. NOTE: You may not see juice dripping with certain produce when only juicing a small quantity. Continue juicing following the juicing 101 guide and ensure drip lever is open.

How do I install the pulp spout?

Ensure auger and filter are installed correctly to allow the pulp spout to fit into place. For units with DC before 1421 Install the pulp spout in the feed chute chamber, on top of the filter, by installing at an angle then turning counterclockwise to lock in place. For DC after 1421, Attach the inner pulp spout to the feed chute chamber by installing at an angle, on top of the filter, then turn counterclockwise to lock in place. Ensure the word Ninja is facing up. Then attach the outer pulp spout by installing at an angle, on top of the inner pulp spout, and turning counterclockwise to lock in place. Follow the arrows printed on the part to ensure correct assembly.

If I am juicing a specific fruit or vegetable, which filter should I use?
