A portable blender may not start or may stop because the battery needs charging, the cup or blade block is not locked, ingredients are obstructing the blade, or repeated blends have caused overheating. Choose your model below, then match its charging lights and error pattern to the relevant checks.
Is power connected and switched on?
Check the battery and charging indicators for your exact portable blender below. Use the specified charging equipment, then disconnect it before following that modelโs start sequence.
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. 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 modelโs 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, charging connection or base is damaged, or a rechargeable base is unusually hot, swollen or deformed, 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 step 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
A misaligned Cup, sleeping controls, low battery, blocked blades or overheating can prevent the Portable Blender from starting or continuing.
Is the Cup aligned and has the blender been woken?
- The Cup of NutriBullet Portable Blender / Portable Blender McLaren must be securely attached and aligned before the motor can start.
- With Power off, check that the two dots on the Cup and Motor Base line up, then secure the Lid with its latch upright.
- Press Power once and wait about one second for a solid blue ring, then press again to start.
- All lights turning off after two minutes without use is sleep.
- Wake the blender again before retrying.
- If the ring flashes red, use the cup-and-blockage checks.
What if the battery is low?
- For NutriBullet Portable Blender / Portable Blender McLaren, LED 1 flashing red means low power.
- Connect the supplied USB-C cable to a suitable 5V, 2A maximum supply while the port is dry, and look for the LEDs to progress towards solid blue.
Why does it start and then stop?
- A 20-second stop on NutriBullet Portable Blender / Portable Blender McLaren normally means the blend cycle has finished.
- If the blades stop early or the ring flashes red, switch off, wait until the blades stop and check for overfilling.
- Reduce a cool mixture below MAX and add enough liquid.
- Secure the Lid, then try shaking or turning the blender upside down to release stuck ingredients before another attempt.
- If food remains stuck, turn Power off and disconnect the charger before clearing it with a utensil, keeping fingers away from the blade.
- Refit the Lid before retrying.
- Stop if the blade still cannot turn.
What do the lights or error indicators mean?
- For NutriBullet Portable Blender / Portable Blender McLaren, alternating upper and lower red LEDs indicate too many blends, so pause and let it cool.
- Do not exceed nine cycles within six minutes, and if a red general-error flash occurs, check the cup is secured and aligned.
What if the ring is red for overheating?
- A red ring on NutriBullet Portable Blender / Portable Blender McLaren can indicate overheating and its thermal breaker stopping the motor.
- Pause and let the blender cool before the next use.
- Never run it for more than one minute at a time.
- A cooling wait should allow the thermal breaker to reset.
- After cooling, check the Cup alignment and reduce an overloaded mixture before another attempt.
- If normal operation does not return, leave the blender off.
Could hard ingredients or an empty Cup be the problem?
- Do not run NutriBullet Portable Blender / Portable Blender McLaren with an empty Cup or with stone-fruit pits or seeds still in the recipe.
- Switch off and wait for all movement to stop before opening the Lid.
- Remove the pits and excess ingredients, add liquid without passing MAX and securely close the Lid.
- Retry only after correcting the load.
- If the blade remains blocked, follow the blockage check instead of repeatedly starting it.
NutriBullet Flip Stainless
A loose Cup, sleeping controls, a battery that needs charging or blocked blades can prevent the Flip Stainless from starting or continuing.
Is the Cup secured and the blender awake?
- For NutriBullet Flip Stainless, secure the cup to the motor-base, blade and lid assembly, press Power to wake and look for a fully illuminated ring. NEVER submerge the entire Motor Base, Blade, and Lid in water.
- Press Power again for a 30-second cycle, and if it will not start, check the ring colour before another attempt.
What if it needs charging?
- The wake-up ring on NutriBullet Flip Stainless shows white when ready, yellow when low and red when it needs charging.
- Use the supplied Charging Cable and Power Supply with a clean, dry USB-C port.
- While connected, flashing red means it still needs charge, flashing yellow means low charge, flashing green means ready for normal use and solid green means fully charged.
- Once sufficiently charged, wake the blender and check its ring again.
- If it still will not start, check the Cup lock rather than repeatedly pressing Power.
Why does it start and then stop?
- The normal blend cycle on NutriBullet Flip Stainless ends after 30 seconds.
- Pressing Power during a cycle also stops it early.
- After 90 seconds without activity, the blender shuts down and its lights go out.
- Press Power once to wake it and again to begin a cycle, starting with the Motor Base, Blade, and Lid on top.
- If the blades stall before the cycle ends, use the load and blockage check.
What do the lights or error indicators mean?
- Flashing yellow on NutriBullet Flip Stainless can mean the Cup is not fully tightened or ingredients are blocking the blades.
- Tighten the Blending Cup to the Motor Base, Blade, and Lid until the ring turns white.
- If it is already secure, let the blender shut down and wait until the blades stop before opening the Cup and carefully dislodging food.
- Use enough liquid and keep the combined ingredients below the MAX fill line.
- Secure the assembly and retry from the upright starting position.
- If yellow returns, stop the attempt.
Is the blender still locked after cooling?
- Flashing red during use means NutriBullet Flip Stainless needs you to stop blending.
- Leave Power untouched for at least 90 seconds so the blender shuts down, and allow it to cool.
- Do not blend continuously or run consecutive cycles for more than one minute in total.
- If it remains locked, keep it off and take your claim, with your receipt, to the place of purchase (the manufacturer warranty is 12 months from the date of purchase).
Did the blade stall at the start of the cycle?
- Start NutriBullet Flip Stainless right-side-up, with the Motor Base, Blade, and Lid on top, to help prevent blade blockage.
- Once blending starts, turn the blender upside down so the ingredients reach the blades and place it on a clean, dry, level surface.
- If it stalls, allow complete shutdown before dislodging ingredients and checking liquid and MAX levels.
- Refit the Cup securely before trying again.
- Stop if the corrected load still cannot blend.
NutriBullet Flip Tritan
A loose Blending Cup, sleeping controls, a battery that needs charging or blocked blades can prevent the Flip Tritan from starting or continuing.
How do I start the NutriBullet Flip Tritan?
- Before fitting or removing parts, unplug the charger and leave Power untouched for 90 seconds so the blender shuts down. Wait until the blades have completely stopped.
- Stand the Blending Cup on a clean, dry, level surface. Add ingredients, following the minimum liquid and MAX fill marks. Do not run an empty Cup.
- Twist the Motor Base, Blade, and Lid securely onto the Blending Cup, then snap the Flip-Top Lid closed and sealed. NEVER submerge the entire Motor Base, Blade, and Lid in water.
- Keep the blender right-side-up, with the Motor Base, Blade, and Lid on top. Press Power once to wake it and wait about one second for the ring to illuminate. A white ring means ready; if it flashes yellow or shows red, use the matching checks below before starting.
- Press Power again to start a 30-second blending cycle. Only once blending begins, turn the blender upside down so the ingredients reach the blades, and place it on a clean, dry, level surface.
What if the ring flashes yellow and the NutriBullet Flip Tritan will not start?
A flashing yellow ring can mean the Blending Cup is not fully tightened.
- With the Motor Base, Blade, and Lid on top, continue tightening the Blending Cup to the assembly until the ring turns white. Keep the Flip-Top Lid snapped shut.
- Once the Cup is secured and the ring is white, use the start sequence above. If the Cup is already secure and yellow still flashes, follow the overload and blade-blockage check below.
What if a Flip Tritan overload or blade blockage stops blending?
Too much food or too little liquid can stop the blades. Flashing yellow can also indicate blocked blades.
- Stop the blending cycle with Power if it is still running. Disconnect the charger if connected, then leave Power untouched for at least 90 seconds to allow complete shutdown. Wait until all blade movement has stopped before opening or removing anything.
- With the Motor Base, Blade, and Lid on top, twist the assembly off the Blending Cup. Carefully dislodge stuck ingredients without touching the sharp blade edges.
- Remove excess ingredients so they stay below MAX, and add enough liquid to meet the Cupโs minimum liquid mark. Do not overfill with ice, and remove stone-fruit pits or seeds before blending.
- Secure the assembly to the Cup and snap the Flip-Top Lid closed. Start with the Motor Base, Blade, and Lid on top; turn the blender upside down only after the blades begin moving.
If the blades remain blocked or the error returns after these checks, leave the blender off and take your claim, with your receipt, to the place of purchase (the manufacturer warranty is 12 months from the date of purchase).
What if the NutriBullet Flip Tritan needs charging?
After waking, a steady yellow ring means low charge; a red ring means it needs charging and must not be used to blend.
- Check that the USB-C port is clean, completely dry and undamaged. Use only the supplied Charging Cable and Power Supply.
- While connected to charge, flashing red means it still needs charging, flashing yellow means low charge, flashing green means ready for normal use, and solid green means fully charged.
- Once charged, unplug the charger, wake the blender and check the ring before following the start sequence above.
What if the NutriBullet Flip Tritan stops after 30 seconds or its lights go out?
A normal blending cycle ends after 30 seconds. Pressing Power during blending also stops the cycle early. After 90 seconds without activity, the blender shuts down and the ring goes out.
For another blend, press Power once to wake the controls, then follow the start sequence above. Do not blend continuously or run consecutive cycles for more than one minute in total.
What if the NutriBullet Flip Tritan flashes red during use?
Flashing red during use is a functional error.
- Stop using the blender immediately.
- Do not press Power for at least 90 seconds, so the blender can shut down automatically.
Leave the blender off and take your claim, with your receipt, to the place of purchase (the manufacturer warranty is 12 months from the date of purchase) with this fault.
NutriBullet Flex Portable / Flex Portable McLaren
A loose Cup or Blade Block, low battery, blocked blade or overheating can stop the blender from starting or continuing. Check the fit, charge, ingredients and warning lights below.
For a McLaren pack, these instructions apply to Australian Papaya product code NBPB07222PA-MC.
Are the Blade Block and Cup correctly locked?
- The Cup, Blade Block and Motor Base of the blender must align and lock before blending.
- With Power off and the charger disconnected, fit the completely dry Blade Block blades-first into the Cup to its soft stop, secure the Sip Lid, then gently twist the Cup-and-Blade assembly clockwise onto the Motor Base.
- Do not force the Blade Block.
- An orange ring blinking six times can mean the Cup is not attached properly or food is obstructing the blade.
- Refit the assembly and use the blockage check if the orange signal returns.
Which button starts blending?
- Press Power once to wake the blender, then check the illuminated LED Battery Bar.
- Press Power again to begin a 30-second cycle.
- White lights move clockwise while blending and become solid white when it finishes.
- The controls go to sleep after 90 seconds without activity, so wake them again before starting.
- If the battery display shows blinking red LED 1, charge the blender before expecting it to operate.
What if charging is the problem?
- For this blender, do not connect the charger while the USB-C cable or port is wet.
- Pat a wet port dry with a lint-free towel and allow it to air dry fully before charging with the supplied cable and the specified 5V, 2A maximum supply.
Why does it start and then stop?
- Too much food or ice, or too little liquid, can stop the blades of the blender.
- If the Cup feels warm or hot, do not open it or blend again.
- Leave it to cool for at least 30 minutes and longer if still warm, then slowly open the Sip Lid away from your face and body.
- For a cool Cup, reduce the load below MAX and add liquid.
- If food remains blocked, power off and unplug, detach the Cup-and-Blade assembly from the Motor Base and gently shake or invert it.
- If needed, stand the vessel on its Sip Lid, carefully detach the Blade Block and clear trapped food.
- Never insert a hand or utensil inside the Cup.
- Reassemble before retrying, and stop if the blockage remains.
What if a general error appears after cup removal?
- For this blender, disengaging the cup during blending can cause a general error.
- Wait for the blades to stop and reattach the cup and blade block correctly, and if the error remains, stop the checks.
Has repeated use overheated the motor?
- A light ring that flashes red for three seconds and then stays red indicates overheating on the blender.
- Pause and allow the blender to cool so the thermal breaker can reset.
- Do not blend continuously or run consecutive cycles beyond one minute total.
- Once cool, check the load and Cup lock before another attempt.
- If the red warning remains, leave the blender off.
What if the Motor Base itself overheats, smells unusual, leaks, bulges or changes colour or shape? Turn the blender off immediately, stop using it and take your claim, with your receipt, to the place of purchase (the manufacturer warranty is 12 months from the date of purchase).
Is LED 1 red or orange?
- A blinking red LED 1 on the Battery Bar means the blender has a depleted battery and cannot operate.
- Solid red means it needs charging, while solid orange means the battery is low.
- Connect the supplied cable to the specified supply only after the cable and charging port are completely dry.
- Wait until LED 1 turns white, which means there is enough charge for a complete blending cycle.
- All four LEDs solid white indicate full charge.
- If it still fails with charge available, recheck the Cup-and-Blade lock.
NutriBullet GO
An unlocked Cup, sleeping controls, low battery, blocked blades or overheating can prevent the GO from starting or continuing.
Is the Cup locked and has Power been held to wake it?
- For NutriBullet GO, screw the base clockwise onto the cup until locked, hold Power for three seconds to wake it and look for a flashing blue light.
- If red and blue flash instead, continue securing the cup before starting.
Do I press Power once or twice?
- For NutriBullet GO, press Power twice in quick succession to start, then press it once to stop.
- If the ready light has timed out before starting, wake the controls again instead of assuming a single press starts blending.
Is the red light flashing for thirty seconds?
- A red light flashing for 30 seconds means the battery in NutriBullet GO is low.
- With the charging connection dry, use the supplied USB cable to charge.
- Red while plugged in means charging and blue while plugged in means fully charged.
- Disconnect charging before the normal wake-and-start sequence.
- If the battery still will not take charge, take your claim, with your receipt, to the place of purchase (the manufacturer warranty is 12 months from the date of purchase).
Did the red light flash ten times?
- Ten red flashes indicate food blocking the blades of NutriBullet GO.
- Switch off and wait until the motor and blades have stopped, then turn the assembled blender upside down before unscrewing the cup from the base.
- Remove excess food so the remaining load stays below MAX.
- Do not use ice, frozen fruit or frozen vegetables.
- Remove fruit and vegetable rinds and peels, and stone-fruit pits or seeds.
- Lock the cup back onto the base and retry the normal start sequence.
- If the blade remains blocked, stop the checks.
Did the red light flash five times?
- Five red flashes mean NutriBullet GO is overheating and must cool before running again.
- Stop using the blender and let it cool.
- Do not operate for more than two consecutive cycles or continuously for more than one minute.
- After cooling, check the cup lock before another attempt.
- If the warning remains, take your claim, with your receipt, to the place of purchase (the manufacturer warranty is 12 months from the date of purchase).
Did it stop after thirty seconds, or after three seconds empty?
- NutriBullet GO normally stops blending after 30 seconds and flashes blue when finished.
- This is a completed cycle.
- An empty-cup start switches the motor off after three seconds.
- Do not run an empty cup: add the intended recipe within MAX and lock the cup before using the normal start sequence.
Is the Cup warm after repeated blending?
- If the Cup of NutriBullet GO feels warm after blending, allow it to cool before trying to detach the blade assembly.
- Once it has cooled, slowly untwist the assembly with the opening pointed away from your body.
- Correct the load before refitting, and keep operation to no more than two consecutive cycles or one minute continuously.
- If the blender still stops early, check the red-flash pattern before another attempt.
