A "smoking motor" is usually caused from binding between the cutting unit clutch and the cutting assembly which connects to the motor. Unplug the blender and allow to cool. Once the blender is cool, check the cutting assembly (see the Use and Care instructions for your model for a parts diagram) to see if the blades "spin freely." Be careful, the blades are sharp. If the blades do not spin freely, the cutting unit needs to be replaced. Once the blender base (without container) is cool, plug it in and turn it on to see if it works properly. (If the unit was not turned off when the cutting unit locked, the motor could be damaged.)
If water is overflowing, the water reservoir is overfilled. There is a drain hole in the rear of the coffeemaker to prevent overfilling. If the overflow is coffee, you may have used more than one tablespoon of coffee per cup of water or not fully seated either the brew basket and/or the carafe underneath the brew basket. Make sure you have correctly aligned the brew basket and the carafe and are using the correct amount of coffee grounds. Overflowing may happen more frequently with decaffeinated, flavored and finely-ground coffee. Overflowing may occur if the paper filter collapses inside the brew basket. Use a good quality paper filter.
The US Department of Agriculture warns against relying on juice as your sole source of nutrition. This kind of diet won’t give you enough protein or fiber to maintain muscle mass and keep you feeling full. When we spoke with nutritionist Shereen Lehman, she reiterated this point. “Juicing alone won’t fix an unhealthy diet,” she told us. “It’s also important to cut out the junk foods and eat more lean protein sources, dairy or calcium sources, whole grains, and more fruits and veggies.”
The commercial-grade Omega J8004 juicer does best with hard fruits and vegetables, and was more efficient than popular (and still great) juicers like the Breville Juice Fountain Plus we tested. It’s great for people on a budget with limited counter space. And with a 15-year warranty, the machine is built to last. In our tests, the J8004 extracted a fair amount of both green juice and carrot-apple juice, falling in the middle of the pack for both tests.
The juicer's side has an indent that molds perfectly to the shape of the pitcher so you always know where to place it. The pitcher lid has an opening at the top that allows juice to drain from the juicer's nozzle directly into the pitcher. There is also a nifty piece of plastic that prevents any froth from making its way from the pitcher to your cup. In our testing, we found that this separator worked well to keep our juice froth-free so you could enjoy it right away. If you prefer froth in your juice, you can remove the separator.
Easy to clean: We’ve found that all juicers have one thing in common—they’re a bit of a pain to clean. The parts aren’t dishwasher safe, so you have to clean the components by hand. And they have a lot of small nooks and crannies that can trap gunk. We looked for vertical juicers that come with specialized brushes to make cleaning easier, and considered horizontal models, like those from Omega, that are a little simpler to clean because the juicing screens aren’t as big.
Dietitian and nutrition writer Sharon Palmer told us that a juicer “should be easy to use, take apart, clean, and store.” Most of the juicers took about 10 minutes to assemble. The $300 Breville and the $400 Hurom both came mostly assembled, but the Tribest ($250) didn’t — and we found its instructions confusing and difficult to follow. KitchenAid’s $300 juicer attachment was hands-down the worst, requiring a full 20 minutes to assemble and almost causing injury thanks to its exposed blade.
Kuvings released the C7000 in 2017. Kohler said this model has improved features compared with the Kuvings Whole Slow Juicer (B6000), which didn’t impress us in testing. From watching a comparison review of the C7000 and the Whole Slow Juicer, we see that the C7000 has a new funnel for easily feeding produce, doesn’t produce as much pulp, and has a more recessed auger for easier cleaning compared with its predecessor. But the C7000 still spins faster than our pick at 60 rpm, and is more expensive at the time of writing. And although Kuvings juicers boast a 3-inch feed tube that, in theory, can accept whole fruit, most apples in the store are much bigger than three inches in diameter, so that’s a wash. When we tested the Whole Slow Juicer, it didn’t hold a candle to the juice quality from Tribest or Omega machines. The Kuvings Silent Juicer was also an underperformer, giving us over an ounce less of green juice than the Slowstar. The resulting juice was also unpleasantly pulpy.
