How can we help?

Why will my juicer not start or keep running?

  • Updated

A juicer may not start or keep running because its bowl, cover, lid or locking arms are not secured, the controls or power connection have changed, pulp or produce is blocking movement, or the motor has overheated. Start with the model-specific lock checks below, then clear the load or allow the stated cooling time.

Is power connected and switched on?

For a corded appliance, check that the plug is fully inserted in a working power outlet and that the outlet is switched on. Set the appliance controls to off before reconnecting a loose plug; use the model’s start sequence after reconnecting.

Are the correct parts fitted and undamaged?

Switch off, disconnect external power and wait for all movement to stop before removing, refitting or cleaning parts or clearing food. Allow hot cooking parts to cool before handling them. Use only the parts intended for the exact model; never force a lock, bypass an interlock or open the motor base.

Check removable parts for cracks, broken tabs or other damage. Stop using a damaged detachable part and replace it before further use; cleaning or tightening will not repair it. If a blade remains seized after the model’s permitted clearing steps, stop using the attachment and take your claim, with your receipt, to the place of purchase (the manufacturer warranty is 12 months from the date of purchase); do not force it or touch its sharp edges.

Has liquid entered the base, or is an electrical part damaged?

If there is liquid inside or under the motor base, or the cord, plug or base is damaged, stop using it, unplug it only if it is safe to do so, and take your claim, with your receipt, to the place of purchase (the manufacturer warranty is 12 months from the date of purchase). Do not try a cooling reset or open the base for this fault.

After completing the relevant checks below, leave the appliance off if normal operation has not returned and take your claim, with your receipt, to the place of purchase (the manufacturer warranty is 12 months from the date of purchase).

If a check directs you to our team, or the appliance still will not start or keep running, see our warranty article.

NutriBullet Juicer 800W

An incorrectly seated Pulp Basin, an unsecured Locking Handle or an overheated motor can prevent the Juicer 800W from starting or continuing.

Are the Pulp Basin, Sieve, Cover and Locking Handle secure?
  • An incorrectly seated Pulp Basin or unsecured Locking Handle can prevent NutriBullet Juicer 800W from starting.
  • Switch off and unplug.
  • Align the Pulp Basin spout with the dimpled side of the Motor Base.
  • Holding the Sieve by its rim, align it to the motor drive coupling and press down until seated.
  • Place the Basin Cover with its side ears aligned to the basin ears.
  • Raise the Locking Handle into those ears until securely locked.
  • Reconnect only after assembly is secure.
  • If it still will not run, check the correct start sequence and cooling instructions.
How do I switch on the motor?
  1. These controls apply to NutriBullet Juicer 800W, product code NBJ07100.
  2. On NBJ07100, turn the dial from OFF to LOW or HIGH after plugging in the assembled juicer.
  3. The green indicator ring should become visible.
  4. The Sieve must be spinning before you add produce.
  5. If it stays still, switch off and recheck the Locking Handle rather than packing food into the chute.
What if the pulp basin is full?
  1. A full Pulp Basin on NutriBullet Juicer 800W must be emptied before juicing continues.
  2. Switch off, unplug and wait until the Sieve is still.
  3. Remove the Juice Pitcher and lower the Locking Handle away from the Basin Cover ears.
  4. Lift the Pulp Basin, cover and Sieve together off the Motor Base and take them to the sink.
  5. Remove the Food Pusher and cover, lift the Sieve by its rim and empty the pulp, using the flat end of the Cleaning Brush if needed.
  6. Refit the basin, Sieve and cover and lock the handle before restarting.
  7. If food still backs up, stop and clean the Sieve.
Is dried pulp blocking the Sieve?
  • With NutriBullet Juicer 800W switched off, unplugged and the Sieve completely still, remove the cover and lift out the Sieve carefully.
  • Use the Cleaning Brush under running water to clear pulp from the Sieve.
  • Avoid its sharp blade teeth.
  • Soak dried-on pulp in hot water for 30 minutes if needed, then brush again and refit the Sieve and cover with the locking parts secure.
  • If the mesh is damaged, use the damaged-part rule above rather than reusing it.
Are you loading the Feed Chute too quickly?
  • Start NutriBullet Juicer 800W with the Sieve spinning before adding produce.
  • Cut ingredients small enough to fit freely and add them gradually, guiding them with the supplied Food Pusher without excessive force.
  • Let one load pass through before adding more.
  • If food stays lodged, switch off, unplug and wait until all movement stops before removing the cover and clearing the trapped food.
  • Refit the Sieve and cover and secure the Locking Handle before restarting.
  • If the motor has stopped from heat, complete its cooling wait first.
  • Do not push food against a stationary Sieve.
Did the Locking Handle move during juicing?
  • The Locking Handle must remain securely engaged while NutriBullet Juicer 800W runs.
  • If it has moved, switch off, unplug and wait until the Sieve stops.
  • Refit the Basin Cover so its ears align with the Pulp Basin, then secure the handle upright over them.
  • Retry only when the handle holds securely.
  • If it will not stay locked, leave the juicer off and follow the damaged-part check above.
Did a long run stop the motor?
  • If NutriBullet Juicer 800W has run continuously for ten minutes, switch off, unplug and leave the motor off for 15 minutes before continuing.
  • If the motor overheats, switch off, unplug and allow at least 15 minutes of cooling.
  • Allow air space around and underneath the base.
  • After cooling, retry only with the basin and cover correctly locked and the ingredient load reduced.
  • If it still does not run, leave it off.
Are unsuitable ingredients straining the motor?
  • Use NutriBullet Juicer 800W for fresh fruit and vegetables, with citrus rind and stone-fruit pits removed.
  • Do not feed frozen produce.
  • If unsuitable food has already been added, switch off, unplug and wait until the Sieve is still before removing the cover and clearing the food.
  • Rebuild the locked assembly and try suitable fresh produce only after any required cooling wait.
  • Stop if the motor remains still.

Do not touch or hold the NutriBullet Juicer 800W while it is hot.

NutriBullet Cold Press Slow Juicer

An unlocked Juice Bowl or Cover, an open wide chute lid, a jammed Auger or overheating can prevent the Cold Press Slow Juicer from starting or continuing.

Are the Juice Bowl and Juice Bowl Cover locked?
  • For NutriBullet Cold Press Slow Juicer, with the switch OFF, seat and lock the juice bowl on the base, then lock its cover clockwise with the locked symbol aligned to the bowl triangle.
  • Select ON only after the cover is secure, otherwise rebuild the assembly.
Why does opening the wide feed chute stop it?
  1. For NutriBullet Cold Press Slow Juicer, opening the wide chute lid pauses the motor and auger, and closing the lid restarts juicing.
  2. If it does not resume with the lid properly closed, turn OFF and check the bowl and cover locks.
How do I clear a jam?
  1. For a jammed NutriBullet Cold Press Slow Juicer, move the switch to OFF and wait until the Auger has stopped completely.
  2. Press the RESET switch underneath the Motor Base, then hold REV for a few seconds.
  3. Return to OFF and again wait until all movement stops before changing to ON.
  4. If reverse does not clear the blockage, switch OFF, unplug and use the disassembly-and-rebuild check.
  5. Stop if normal juicing does not return after reassembly.
Why does it start and then stop?
  1. The motor of NutriBullet Cold Press Slow Juicer can stop when it overheats.
  2. Switch OFF, unplug and allow at least 15 minutes of cooling before another attempt.
  3. When juicing rapidly or with firm pressure, do not run for more than 15 minutes at a time and give the motor a one-minute rest between uses.
  4. Keep at least 200 mm of air space above and on every side of the appliance.
  5. Retry with suitable produce and a correctly locked bowl and cover.
  6. If it stops again, leave it off.
Are you feeding unsuitable food or pushing too hard?
  • Some ingredients can obstruct or damage NutriBullet Cold Press Slow Juicer: do not use frozen produce, unremoved stone-fruit pits or cores, or low-juice foods such as bananas, avocados and coconuts.
  • Avoid hard fruits or thick vegetables rich in fibre and starch.
  • Cut produce to fit without force and cut long, hard fibres into four-inch pieces.
  • Feed gradually with the Food Pusher, allowing each load to move through before adding more.
  • If food will not pass, switch OFF and follow RESET and REV instead of pressing harder.
  • If that fails, unplug and clear the food after disassembly.
How do I rebuild the bowl after a jam?
  1. Switch NutriBullet Cold Press Slow Juicer OFF, unplug and let it cool before disassembly.
  2. Once the Auger is still, remove the Juice and Pulp Containers, turn the Juice Bowl Cover anticlockwise and lift it off, then remove the Auger.
  3. Lift the Juice Bowl from the Motor Base and separate the Rotating Bowl Brush and Juicing Screen to remove trapped food.
  4. Refit the bowl securely, put the screen into the brush and seat them in the bowl, then turn and press the Auger onto the centre axis until secure.
  5. Fit the cover and rotate it clockwise until the locked symbol aligns with the bowl triangle.
  6. Replace both containers before reconnecting.
  7. If the correctly rebuilt juicer will not operate, leave it off.
Are the Juice and Pulp Containers full?
  • Stop NutriBullet Cold Press Slow Juicer when the Juice Container is full or food has finished processing.
  • Turn the switch OFF, wait for movement to stop and empty both the Juice and Pulp Containers before the next round.
  • Put them back beneath their corresponding spouts before switching ON.
  • Add ingredients gradually.
  • If the containers are empty but food still does not pass, use the jam check.

Do not touch or hold the NutriBullet Cold Press Slow Juicer while it is hot.
