00:00Is your ninja slushy beeping once every minute, with the lights on top flashing in a downward spiral?
00:05That's the machine warning you. Your mix doesn't have enough sugar to freeze properly.
00:10Here's how to fix it fast so you can get back to slush mode.
00:13Step 1. Check your ingredients.
00:16The most common cause is a sugar-free or low-sugar mix.
00:20Diet sodas, unsweetened juices, or zero-calorie blends might taste sweet,
00:24but they lack the real sugar your slushy needs to operate.
00:26The machine requires at least 4% sugar content to freeze properly.
00:30Step 2. Add a sugar-based ingredient to fix the mix.
00:34Stir in 1-2 tablespoons of one of the following.
00:37Simple syrup, honey, maple syrup, agave, fruit juice concentrate, or a low-calorie option like allulose.
00:44Mix it thoroughly so the sugar is evenly distributed.
00:47Step 3. Reset and restart the cycle.
00:51Press the preset button once to cancel the alert.
00:53Then press it again to start a fresh cycle.
00:55The machine will attempt to freeze the updated mix.
00:59If the beeping stops and the lights return to normal, you're good.
01:03Still getting alerts?
01:04Add a little more sweetener or switch to a better mix next time.
