00:00Ninja slushy making loud noises? Here's the fix.
00:04The ninja slushy isn't silent, but if yours suddenly sounds louder than usual,
00:08rattling, grinding, or shaking, something's probably off.
00:12Here's how to quiet things down fast.
00:14Step 1. Make sure it's on a level, stable surface.
00:17Uneven counters or wobbly placement can make the machine vibrate more than it should.
00:22Use a damp towel or anti-slip mat under the base to reduce movement and noise.
00:25Step 2. Check for hardened or icy mix inside.
00:29If your slush base froze too solid, the paddle may be struggling to spin through it,
00:34creating loud knocking or straining sounds.
00:37Let the container sit at room temp for 5 minutes, then stir before restarting.
00:42Step 3. Inspect the container and paddle for damage.
00:45Cracks, bent paddle fins, or loose parts can throw things off balance.
00:50Make sure everything is clean, aligned, and properly assembled before running the next cycle.
00:55Step 4. Don't overfill the container.
00:57Too much liquid creates pressure and sloshing that amplifies noise.
01:02Stick to the max fill line, about 470 milliliters, 16 oz, to keep operation smooth.
01:09If the noise continues after checking everything, it could be a sign of wear inside the motor housing.
