Most NutriBullet parts are dishwasher safe, but the motor base and blade assembly must be hand-washed

The short answer: your NutriBullet cup, lid, and most accessories can go in the dishwasher on the top rack. The motor base, blade assembly, and rubber gasket cannot. Hand-washing the blade assembly takes about two minutes and prevents damage to the motor housing and seals that dishwasher heat and water pressure can harm.

NutriBullet makes several models—the original NutriBullet, NutriBullet Pro, NutriBullet Rx, and NutriBullet Balance—and dishwasher safety is the same across all of them. The rule is straightforward: anything that plugs in or contains moving parts stays out of the dishwasher.

Key Takeaways

  • The plastic cup, lid, and flip-top cap are all top-rack dishwasher safe on all NutriBullet models.
  • The motor base, blade assembly, and rubber gasket must be hand-washed when ready after use to prevent mineral buildup and seal damage.
  • Hand-washing the blade assembly takes two minutes: soak it in warm soapy water, scrub between the blades with a soft brush, rinse, and air-dry upright.
  • Putting the blade assembly in the dishwasher can crack the gasket, corrode the motor connection points, and eventually cause leaks into the motor housing.

What goes in the dishwasher and what does not

The cup, lid, and flip-top cap are made of durable plastic and are designed to withstand dishwasher temperatures. Place them on the top rack only—the bottom rack exposes them to hotter water and stronger spray patterns that can warp thin plastic over time. They will not be damaged by a standard wash cycle.

The motor base—the part that sits on your counter and plugs into the wall—must never go in the dishwasher. Water can seep into the electrical connections and damage the motor. The blade assembly (the part that screws onto the cup) and the rubber gasket (the seal between the blade assembly and the cup) also stay out. The gasket is especially vulnerable: dishwasher heat can crack it or cause it to shrink, leading to leaks when you blend.

Any accessories that came with your NutriBullet—such as the flat blade for nut butters or the emulsifying blade—should be hand-washed as well. Check your manual if you are unsure about a specific piece.

How to hand-wash the blade assembly the right way

Hand-washing takes less time than loading a dishwasher if you do it right after blending. Fill a bowl or your sink with warm water and a drop of dish soap. Submerge the blade assembly for 30 seconds to loosen dried material.

Use a soft-bristled brush or an old toothbrush to scrub between the blades and around the base where the gasket sits. Do not use a scouring pad or steel wool—these scratch the plastic and can damage the gasket. Rinse under running water, holding the assembly upright so water flows away from the motor connection point (the threaded part that screws onto the cup).

Stand the blade assembly upright on a clean towel to air-dry. Do not lay it flat, because water can pool around the gasket and seep into the motor connection. Once it is completely dry, store it in a cabinet or drawer away from heat and direct sunlight, which can degrade the rubber gasket over time.

Why the blade assembly cannot handle the dishwasher

The blade assembly is not sealed the way the cup is. The gasket that sits between the assembly and the cup is designed to create a watertight seal only when the two parts are screwed together tightly. In the dishwasher, water sprays directly onto the gasket and the motor connection threads from all angles. Over multiple cycles, this causes three problems.

First, mineral deposits from hard water build up on the gasket and threads, making it harder to screw the assembly onto the cup and eventually causing it to leak. Second, the heat of a dishwasher cycle (usually 140 to 160 degrees Fahrenheit) can warp the rubber gasket permanently, so it no longer seals properly. Third, water can work its way into the motor connection and corrode the metal contact points, which can cause the blender to stop working or malfunction.

Hand-washing prevents all three problems and takes only a couple of minutes per use.

Cleaning the cup and lid properly

Even though the cup and lid are dishwasher safe, you can extend their life by rinsing them when ready after blending. Dried smoothie or nut butter can be stubborn to remove and may require soaking, which defeats the convenience of a dishwasher.

Rinse the cup under warm running water right after you pour out your drink. If you are blending thick mixtures like nut butters or frozen fruit, fill the cup halfway with warm water, add a drop of dish soap, screw on the blade assembly, and run it for 10 seconds. This self-cleans the cup and the blades at the same time. Pour out the soapy water, rinse, and then hand-wash the blade assembly as described above.

If you do put the cup in the dishwasher, avoid the bottom rack and do not use the heat-dry setting. Air-dry it instead, or dry it by hand with a soft cloth.

Common mistakes that damage your NutriBullet

The most common mistake is putting the entire assembled blender—cup, blade assembly, and all—in the dishwasher. This exposes the gasket and motor connection to water and heat they are not designed to handle. Even one cycle can begin to degrade the seal.

Another mistake is laying the blade assembly flat to dry. Water pools around the gasket and seeps into the motor connection threads. Always stand it upright.

A third mistake is using a dishwasher's heat-dry setting on the cup. The intense heat can warp the plastic slightly, making it harder to screw the blade assembly on tightly, which compromises the seal. Air-dry instead.

Finally, some people scrub the blade assembly with steel wool or a scouring pad to remove stubborn residue. This scratches the plastic and can tear the rubber gasket. A soft brush and warm soapy water are all you need.

Frequently Asked Questions

Can I put the whole assembled blender in the dishwasher if I use the gentle cycle?

No. Even a gentle cycle exposes the gasket and motor connection to water and heat that will eventually damage them. The gentle cycle is slower, not cooler, so it does not protect the seal. Always separate the blade assembly from the cup before washing anything.

What should I do if water gets into the motor base?

Stop using the blender when ready and unplug it. Let it sit upside down on a towel for 24 to 48 hours to dry completely. Do not try to use it until you are certain all moisture has evaporated. If the blender does not work after drying, the motor may be damaged and the unit may need to be replaced.

Is the rubber gasket replaceable?

Yes. NutriBullet sells replacement gaskets separately, and they are inexpensive. If your gasket cracks, shrinks, or no longer seals properly, order a replacement from the NutriBullet website or an authorized retailer. Installation takes 10 seconds—just remove the old gasket and press the new one into place.

Can I soak the blade assembly overnight to remove stuck-on food?

Yes, but stand it upright in the bowl so the motor connection threads stay above the water line. Soaking for a few hours or overnight will soften dried material, making it easier to brush away. Just make sure the gasket and threads do not stay submerged for extended periods.

Do all NutriBullet models have the same dishwasher rules?

Yes. The NutriBullet, NutriBullet Pro, NutriBullet Rx, and NutriBullet Balance all follow the same rule: cup and lid on the top rack of the dishwasher, blade assembly and motor base hand-washed only. Check your specific model's manual if you have questions about accessories.
