The KitchenAid K400 blender in Blue Velvet: 56 ounces, real presets and a five-year warranty
The KitchenAid K400 is a 56-ounce blender with a die-cast base, five speeds and presets that run a whole cycle on their own. And KitchenAid backs the K400 blender with a five-year limited warranty, in Blue Velvet and four more colors we link.
One owner of the KitchenAid K400 bought it to match a KitchenAid stand mixer, and that's a good reason to choose a blender. Because the K400's base is heavy, it's a blender that stays out on the counter, so its color is one you'll see every day. And Blue Velvet, the soft blue KitchenAid also uses on its Artisan mixer, is the K400 color most likely to draw a comment.
You make smoothies, frozen drinks or soups most weeks, and you'd like a blender that stays on the counter beside a KitchenAid mixer.
You'd like a glass jar, or a quiet blender for early mornings. The K400's jar is plastic, and owners say the K400 is loud.
Five years, limited, from KitchenAid. KitchenAid chooses whether to replace the blender or repair it.
Amazon, in all five colors we link.
What the KitchenAid K400 does
The KitchenAid K400 blends in a 56-ounce jar on a 1,200-watt motor, and its base is die-cast metal. So the K400 is heavy, and it stays put on the counter while it runs. And a dial gives you five speeds, for when you'd like to decide the texture yourself.
The KitchenAid K400's presets are the reason to choose it over a simpler blender. Because the K400 has presets for smoothies, icy drinks and crushed ice, you choose a preset, press start, and the blender runs the cycle and stops when it's done. And one owner who uses the presets for crushed ice and frozen drinks calls them awesome.
The KitchenAid K400 also has a cleaning preset, and owners like it. But one owner says you'll still need to scrub the jar now and then.
The KitchenAid K400's base is 7.6 inches wide and 9 inches deep, by KitchenAid's figures. So the K400 takes up little room on the counter for a full-size blender, and one owner says the footprint is small. And the Blue Velvet K400 we link is the version Amazon lists with a tamper, a stick for pushing a thick blend down onto the blade.
What the KitchenAid K400 doesn't do
The KitchenAid K400 isn't quiet, and owners who love it say so too. So if you blend while the house is still asleep, the K400 may wake someone up.
The KitchenAid K400's jar is plastic, not glass, and the jar is where most of the complaints are. And some owners say their jar began to leak after two or three years, and that a replacement jar was hard to find. But those years fall inside KitchenAid's five-year warranty, and one owner says KitchenAid replaced a leaking K400 under the warranty.
The KitchenAid K400's weight is a con too, if your blender lives in a cabinet. Because the die-cast base is heavy, the K400 suits a kitchen with a spot for it on the counter.
What owners say about the KitchenAid K400
On Amazon, the KitchenAid K400 in Passion Red, white and black scores 4.5 out of 5 from 1,577 ratings (September 2026). Then the K400's Blue Velvet listing scores 4.1 out of 5 from 36 ratings, and the Pistachio listing 3.7 out of 5 from 8 ratings.
"I really like this blender. It’s powerful, quiet, easy to use, and looks very nice."
Amazon customer, verified purchase, April 2022, in Blue Velvet
"It’s a great blender. We’ve been using it at least once a day. Easily chops through ice and other hard bits with ease."
Amazon customer, verified purchase, January 2025, in Blue Velvet
"I’m not sure why there are so many bad reviews, it almost kept me from purchasing this blender but I love my KitchenAid stand mixer so I decided to get this to match."
Amazon customer, verified purchase, July 2020, in white
But not every owner of the KitchenAid K400 is happy, and the complaints are about the noise and the jar.
"The only con I have is that it’s very loud but it is a POWERFUL blender so I don’t mind."
Amazon customer, verified purchase, July 2020, in white
"The base is great, very sturdy machine. But unfortunately they pair it with a cheaply made carafe. Mine leaks every time I use it."
Amazon customer, verified purchase, September 2025, in Blue Velvet
"We purchased one in 2022, Kitchenaid replaced it under the warranty in 2024 and the new unit is now leaking."
Amazon customer, verified purchase, March 2026, in Blue Velvet
The owner whose K400 was replaced under the warranty found the replacement leaking too, two years later.
The KitchenAid K400's colors, and where to buy each color
We link five KitchenAid K400 colors, and Amazon sells all five colors. So the three K400 colors that aren't neutrals are Blue Velvet, Passion Red and Pistachio. And white and black are there for a kitchen that already has its color somewhere else.
Blue Velvet and Pistachio are also KitchenAid Artisan stand mixer colors. That way a K400 and an Artisan can share one color on the counter.
Amazon's returns follow the seller on each listing. And whichever seller you choose, the warranty is KitchenAid's.
Who makes the KitchenAid K400
KitchenAid is a Whirlpool Corporation brand. And KitchenAid's warranty on the K400 is five years, limited, so KitchenAid chooses whether to replace the blender or repair it, and the warranty starts on the day the K400 is delivered.
There's no recall on record for the KitchenAid K400 at the US Consumer Product Safety Commission, and no KitchenAid blender recall under any model number (checked September 2026).
What goes with the KitchenAid K400
The KitchenAid K400 in Blue Velvet matches the KitchenAid Artisan stand mixer in Blue Velvet, because KitchenAid uses the same color name on both. So the KitchenAid Artisan article covers the mixer, and what it does and doesn't do.
The KitchenAid K400 isn't the only blender in color, though. The blender guide shows the other blenders we link, color by color.
Before you buy the KitchenAid K400
- Noise: if you blend early in the morning, know that owners call the KitchenAid K400 loud.
- Jar: keep your receipt, because the K400's warranty runs five years and some owners' jars began to leak after two or three years.
- Color: if you're matching a KitchenAid Artisan mixer, choose Blue Velvet or Pistachio, which the two appliances share.
- Counter: plan a spot to leave the K400 out, because the die-cast base is heavy to lift.
