How can we help?

A part of my portable blender is damaged. What should I do?

  • Updated

Stop using damaged parts; replace removable parts with the correct parts for your model and seek support for electrical damage. Check below to identify whether the problem is a damaged component, trapped residue or an incorrectly fitted part.

Before inspecting removable parts, switch off, disconnect from power, wait for all moving parts to stop and let hot parts cool. Keep sharp edges away from your fingers, and follow the instructions for a warm or stuck sealed cup before opening it.

Is the problem in the motor base, power connection or charging equipment?

If there is a burning smell, smoke, sparks, an electric shock, a damaged cord or plug, liquid inside or underneath an electrical base, damage after a drop, or a machine that will not switch off, 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 run another test, charge it again, open the electrical housing or attempt a cord repair. An electrical base exposed to liquid needs assessment by a qualified person before reuse.

Use the supply specified on the rating label and in the model guide. Do not modify plugs or use voltage converters; where your model guide prohibits an external timer, connect to the permitted supply directly so a timer cannot restart the motor after overheating.

Could a hard pit or foreign object have damaged the blades?
  • Stop the blender and wait for the blades to finish moving before opening the cup. Disconnect the charging cable before handling the blade area.
  • Remove fruit pits, utensils and other non-food items from the ingredients. Check the blades and cup for damage after contact with a hard object; keep fingers away from cutting edges.
  • Do not try another blend with a bent blade or a cracked cup. Use ingredients suitable for your model and never run an empty cup to test the motor.

If a check above directs you to our team, or you need help with an unresolved issue in this article, see our warranty article.

NutriBullet Portable Blender / Portable Blender McLaren

Keep damaged parts of your NutriBullet Portable Blender / Portable Blender McLaren out of use; replace damaged removable parts with the correct components and seek support for electrical damage.

Is the blending cup or drinking lid cracked or damaged?
  • Switch the blender off and disconnect its charging cable before inspecting the detachable cup or lid. Wait for all blade movement to finish.
  • Look around the cup, rim, threads and lid for cracks, distortion or broken components. Do not keep using a cloudy cup.
  • Identify whether you need the cup or lid and replace the damaged part with the correct model-specific accessory. The replacement must close securely before use.
Is the blade bent, damaged or exposed?
  • Keep fingers away from the blade edges and inspect the Motor Base visually while the blender is off and disconnected.
  • A bent or damaged blade must stay out of use.
  • Use the cup to cover the cutting edges during storage. Arrange the correct replacement or assessment before using the blender again.
Could heat or the cleaning method have damaged a component?
  • Check whether the affected component was placed in a dishwasher, microwave or exposed to excessive heat. The Motor Base is not dishwasher-safe.
  • Use the top rack without the heat/sanitise cycle for dishwasher-safe removable parts. Wipe the motor base separately and keep water out of the charging port.
  • Replace a cracked, warped or damaged detachable part. Cleaning it again will not restore its original fit.
Is the cup warm, pressurised or spraying when opened?
  • Leave the cup where it is and do not open or detach it from the base. Allow at least 30 minutes to cool, and longer if it is still warm; do not blend again.
  • Once cool to the touch, slowly open the Sip and Carry Lid away from your face and body, then pour the contents into another container.
  • Use only cool or room-temperature ingredients and keep carbonated ingredients out of the cup. Do not leave blended food sealed for prolonged periods; fermentation can build pressure. Keep continuous or consecutive blending to no more than one minute total.
Are ingredients jamming the blade or is the cup incorrectly attached?
  • A flashing-red general error can mean the cup is not secured or the blade is blocked. With the blender off and the cable disconnected, check that the cup is aligned and fully secured.
  • If food is stuck, add liquid and reduce the load below MAX; gently shake or invert the closed blender to loosen ingredients. If necessary, switch off and use a utensil to clear the obstruction without touching the blades.
  • Refit the lid and cup securely before trying a normal blend. If the blade remains stuck or looks damaged, stop and arrange help rather than forcing it.
Could the charger, charging position or temperature be wrong?
  • Check the charger label and the cable before connecting them. Use the supplied USB cable and an approved power supply with rated output 5V 2A MAX; do not use a rapid or higher-wattage charger.
  • Charge on a stable surface away from paper, bedding, soft furnishings, flames and direct heat. Keep the charging area and USB-C port dry and clean; do not insert objects into the port.
  • Use an ambient charging/storage temperature of 10–40°C. Keep the cable fully clear of hot surfaces, sharp bends and places where someone could pull or trip on it.
  • For swelling, discolouration, a change of shape, abnormal heat or odour from the base, follow the electrical-fault check above. The built-in lithium-ion batteries are not user-replaceable.
Is the blender showing its overheat warning?
  • If the light ring is solid red, pause and allow the blender to cool before further use. Alternating top/bottom red LEDs mean too many blends.
  • Do not exceed nine blending cycles within six minutes, and keep continuous blending within one minute.
  • Only resume when the blender has cooled and shows no damage, burning odour or other warning sign. A recurring red error needs assessment.

NutriBullet Flip Stainless

Keep damaged parts of your NutriBullet Flip Stainless out of use; replace damaged removable parts with the correct components and seek support for electrical damage.

Is the blending cup or drinking lid cracked or damaged?
  • Switch the blender off and disconnect its charging cable before inspecting the detachable cup or lid. Leave the NutriBullet Flip undisturbed for 90 seconds so it shuts down completely, and check that the blades have stopped.
  • Look around the cup, rim, threads and lid for cracks, distortion or broken components.
  • Identify whether you need the cup or To-Go Lid and replace the damaged part with the correct model-specific accessory. The replacement must close securely before use.
Is the blade bent, damaged or exposed?
  • Keep fingers away from the blade edges and inspect the Motor Base, Blade, and Lid visually while the blender is off and disconnected. NEVER submerge the entire Motor Base, Blade, and Lid in water.
  • A bent or damaged blade must stay out of use.
  • Use the cup or Blade Cover to cover the cutting edges during storage. Arrange the correct replacement or assessment before using the blender again.
Could heat or the cleaning method have damaged a component?
  • Check whether the affected component was placed in a dishwasher, microwave or exposed to excessive heat. The Motor Base, Blade, and Lid must never go in the dishwasher.
  • Wash only the Blending Cup and To-Go Lid on the top rack, without a heat/sanitise cycle; hand-clean the blade and sip hole as shown in the guide, keeping the USB-C port dry.
  • Replace a cracked, warped or damaged detachable part. Cleaning it again will not restore its original fit.
Is the cup warm, pressurised or spraying when opened?
  • Stop blending and wait until the motor and blades have stopped before opening the Flip-Top Lid.
  • Open the drinking-spout lid slowly, pointing it away from your face and body, and be alert for escaping steam, gas or splashing food. Do not unscrew the Motor Base, Blade, and Lid while the motor is running.
  • Use only cool or room-temperature ingredients and keep carbonated ingredients out of the cup. Do not leave blended food sealed for prolonged periods; fermentation can build pressure. Keep continuous or consecutive blending to no more than one minute total.
Are ingredients jamming the blade or is the cup incorrectly attached?
  • Flashing yellow during use can mean the cup is not tight or ingredients have blocked the blade. Let the blender shut down for 90 seconds and disconnect the cable before checking.
  • Tighten the Blending Cup to the Motor Base, Blade, and Lid; the ring should turn white when correctly secured. For a blockage, carefully dislodge the food while keeping fingers off the blade, use enough liquid and reduce the load below MAX.
  • Start blending with the Motor Base, Blade, and Lid on top, then turn the blender over as instructed so the ingredients reach the spinning blade. If the obstruction or error returns, keep the blender out of use.
Could the charger, charging position or temperature be wrong?
  • Check the charger label and the cable before connecting them. Use only the Charging Cable and Power Supply supplied with the NutriBullet Flip; do not substitute a rapid charger.
  • Charge on a stable surface away from paper, bedding, soft furnishings, flames and direct heat. Keep the charging area and USB-C port dry and clean; do not insert objects into the port.
  • Use an ambient charging/storage temperature of 10–40°C. Keep the cable fully clear of hot surfaces, sharp bends and places where someone could pull or trip on it. Do not leave the blender connected to a car lighter port while starting the car.
  • For swelling, discolouration, a change of shape, abnormal heat or odour from the base, follow the electrical-fault check above. The built-in lithium-ion batteries are not user-replaceable.
Is the blender showing its overheat warning?
  • Flashing red during use means a functional error. Stop using the blender and leave the Power Button untouched for at least 90 seconds so it shuts down.
  • For overheat and automatic lockout, allow the blender to cool. If it is still locked after 10 minutes, leave it off and request support.
  • Do not run consecutive blending cycles longer than one minute total; never use a cooling pause as permission to retry a blender that smells burnt or is damaged.

NutriBullet Flex Portable / Flex Portable McLaren

Do not blend continuously or run consecutive cycles for more than one minute total; stop if the cup becomes warm.
Are ingredients jamming the blade or is the cup incorrectly attached?
  • Six orange flashes can mean a blocked blade or an incorrectly attached cup. Turn off the blender and unplug the charger before detaching anything.
  • Remove the cup/blade assembly from the Motor Base and gently shake or invert it to dislodge ingredients; add more liquid if required. For a persistent blockage, stand the vessel upside down on the Sip Lid with Carry Loop, carefully detach the Blade Block and remove the trapped food. Never put a hand or utensil inside the cup to clear it.
  • Refit the Blade Block to the Blending Cup to its built-in soft stop, then gently twist the assembly onto the Motor Base until secure. Do not force the lock; if the blockage or error remains, leave the blender off.
Could the charger, charging position or temperature be wrong?
  • Check the charger label and the cable before connecting them. Use the supplied USB cable and an approved power supply with rated output 5V 2A MAX; do not use a rapid or higher-wattage charger.
  • Charge on a stable surface away from paper, bedding, soft furnishings, flames and direct heat. Keep the charging area and USB-C port dry and clean; do not insert objects into the port.

  • For swelling, discolouration, a change of shape, abnormal heat or odour from the base, follow the electrical-fault check above. The built-in lithium-ion batteries are not user-replaceable.
  • If battery fluid leaks, avoid contact with it. If it touches your skin, eyes or clothing, rinse the affected area with water immediately and seek medical advice.
Has the Sip Lid with Carry Loop gasket moved out of place?
  • Remove the Sip Lid with Carry Loop after the blender is off and all blade movement has stopped.
  • If the gasket moved during washing or drying, remove excess moisture from the gasket area, then gently guide the gasket back into position.
  • Check that the lid closes correctly. A torn or damaged lid component needs replacement; do not mistake a damaged component for a seal that merely needs reseating.
Is the blender showing its overheat warning?
  • An overheat warning flashes red for three seconds and then stays solid red. Pause and let the blender cool before further use.
  • Reduce an overfilled load and add sufficient liquid before another normal blend.
  • If the warning returns after cooling, stop further attempts and arrange assessment; do not retry when there is burning odour, distortion or other damage.
