The Ninja BL610 Professional Blender is built for volume. Its 72 ounce pitcher and stacked blade system handle ice, frozen fruit, and thick smoothies with ease.
But high torque and stacked blades create residue traps, gasket stress, and heat buildup.
Most Ninja BL610 problems do not start with the motor. They start with poor cleaning habits, moisture retention, or overfilling.
This guide covers daily cleaning, deep sanitation, leak prevention, overheating control, and long-term care so your BL610 keeps blending at full strength.

Why Ninja BL610 Maintenance Matters
The BL610 includes:
- A stacked blade tower
- BPA-free plastic pitcher
- Rubber gasket seals
- High-speed motor base
Common issues caused by neglect include:
- Ninja BL610 is leaking from the bottom
- Ninja blender smells like burning
- Mold under the gasket
- Loud grinding noise
- The blade stack is not spinning
Food particles often collect between stacked blades. Moisture can remain under the gasket. Both create odor and bacterial growth.
Routine care protects:
- Blade rotation smoothness
- Gasket compression
- Motor cooling airflow
- Pitcher clarity

How to Clean the Ninja BL610 After Every Use
Daily cleaning prevents most long-term failures.
Step-by-Step Routine
- Unplug the blender.
- Rinse the pitcher immediately after use.
- Fill halfway with warm water.
- Add one drop of mild dish soap.
- Pulse for 20 to 30 seconds.
- Rinse thoroughly.
- Air dry upside down with lid removed.
Never reassemble while wet.
Stacked blades trap moisture. If sealed while damp, odor and mold develop quickly.
If blending peanut butter or thick sauces, soak for 10 minutes before the rinse cycle.
Deep Cleaning the Stacked Blade System
The stacked blade column is the most overlooked area.
Residue hides between blade layers.
Weekly Vinegar Reset
- Fill the pitcher with 50 percent white vinegar and 50 percent warm water
- Blend for 45 seconds
- Let sit for 15 minutes
- Rinse thoroughly
Manual Blade Cleaning
- Remove the blade stack carefully
- Use a narrow bottle brush
- Clean between each blade level
- Rinse and air dry fully
Never place fingers between blades.
Even though Ninja blades are not razor-thin, they are sharp enough to cause injury.
Ninja BL610 Smells Like Burning
A burning smell usually indicates motor strain.
Common causes:
- Overfilling above the max line
- Blending frozen fruit without enough liquid
- Running multiple cycles without rest
- Thick mixtures that stall blade rotation
The BL610 motor builds heat under resistance.
What To Do
- Stop blending immediately
- Unplug
- Allow 30 minutes to cool
- Check the blade stack for stuck debris
- Inspect bottom vents for dust buildup
Repeated overheating shortens motor life.

Ninja BL610 Leaking From Bottom
Leaks usually trace back to gasket wear or improper seating.
Causes include:
- Sticky gasket
- Over tightening blade assembly
- Cracked pitcher base
- Storing a pitcher assembled while damp
Early Warning Signs
- Moisture under the base
- Brown liquid seepage
- Slight wobble when tightening
Replace worn gaskets immediately to protect the motor housing.
Blade Stack Not Spinning Properly
If blades stop spinning:
- Check proper seating on the motor base
- Remove and inspect for food blockage
- Allow the motor to cool
- Confirm pitcher is locked into position
Stacked blades increase torque stress. Resistance buildup affects performance quickly.
Heavy Use Cleaning Schedule
If blending daily:
- Rinse after every use
- Deep clean the blade stack twice weekly
- Remove and dry the gasket twice weekly
- Inspect vents weekly
- Avoid blending for longer than 60 to 90 seconds continuously
Heat and moisture accumulate faster with frequent use.
Seasonal Deep Cleaning Routine
Every 2 to 3 months:
- Disassemble pitcher, lid, blade stack, and gasket
- Soak in warm water with baking soda for 30 minutes
- Scrub lid grooves and handle channels
- Clean base vents using a soft brush
- Inspect the power cord for wear
Humidity accelerates mold growth.
Increase frequency in the summer months.
Long-Term Storage Tips
If storing for weeks:
- Clean and dry all parts completely
- Store the lid off the pitcher
- Never store a pitcher on base
- Keep in a cool, dry cabinet
- Avoid stacking moist components
Airflow prevents odor retention.
Mold Prevention in Humid Kitchens
High humidity increases mold risk around:
- Gasket edges
- Blade base threads
- Lid corners
Prevent mold by:
- Air drying all components separately
- Removing the gasket every few uses
- Never sealing the unit while damp
- Running a monthly vinegar rinse
Replace gaskets if odor persists after cleaning.
Replacement Part Care
When replacing the pitcher, blade stack, or gasket:
- Hand wash before first use
- Avoid high-heat dishwasher cycles
- Confirm model compatibility
- Store spare gaskets in dry sealed bags
Blade stacks are not universal across Ninja models.
Ninja BL610 Troubleshooting and Maintenance Questions
Why does my Ninja BL610 smell like burning during blending?
A burning smell usually means the motor is overheating from thick or overloaded blends. This often happens when blending frozen fruit without enough liquid or running multiple cycles without rest. Stop immediately and allow the unit to cool for at least 30 minutes before restarting.
Why is my Ninja BL610 leaking from the bottom?
Leaks typically occur when the rubber gasket is worn, misaligned, or compressed from overtightening. Overfilling above the max line also increases pressure on the seal. Inspect the gasket for cracks and replace it if moisture continues to appear under the base.
Why are the Ninja BL610 blades not spinning properly?
Blade rotation can stall when food debris is trapped between stacked blades or the blade assembly is not seated correctly. Thick mixtures without sufficient liquid increase resistance and strain the motor. Disassemble, clean thoroughly, and allow cooling before retrying.
Can the Ninja BL610 overheat?
Yes, especially during dense blends longer than 60 to 90 seconds. High torque creates rapid heat buildup inside the motor housing. Allow rest intervals between heavy cycles to protect internal components.
How do I prevent mold under the Ninja BL610 gasket?
Mold forms when moisture remains trapped around the rubber seal. Remove and air-dry the gasket every few uses, and never store the pitcher assembled while damp. A monthly vinegar rinse helps eliminate hidden bacteria.
Final Thoughts
The Ninja BL610 is powerful and simple.
But stacked blades create cleaning blind spots.
Heat buildup creates motor stress.
Moisture creates mold risk.
Daily rinsing prevents odor.
Seal care prevents leaks.
Rest cycles prevent overheating.
Maintenance is mechanical stewardship.
With proper care, your Ninja BL610 will deliver years of strong blending without odor, leaks, or shutdown issues.
