Functionality and Versatility

Smoothie: The KitchenAid Diamond 5-Speed Blender makes excellent smoothies from soft fruit and vegetables but outputs a bit grainy drinks from hard ingredients like carrots or leave some small green flecks when processing leafy food like kale, spinach, and others. It takes another 2-3 minutes to blend them into the decently smooth consistency. So, it takes some effort to process quality green smoothies using the KitchenAid machine.

This machine will well homogenize nicely nuts or ginger root added to the smoothies. However, it will not handle well strawberry or blueberry partly processing it and partly leaving them intact.

In addition, it is not powerful enough to easily deal with thick mixers when it becomes thick the machine tends to form air pockets, slow down the speed, and make whirring sounds. So, the user always has to add a sufficient amount of liquid to keep mixture watery.

Juicing: No blender is designed to make a textbook juice by separating fiber and liquid. However, if blender makes a smooth smoothie than sometimes it called whole Juice. The KitchenAid is able to make “whole juice” with some efforts and needs to blend for 2-3 minutes in total.

Frozen ingredients/desserts: This machine can turn ice cubes into snow. The Ice automatic setting will do it perfectly well by pulsing content for 30 seconds or the manually used pulse function also might be used for this purpose. It is perfect for snow cones or moonshine slushies. However, blending frozen fruits in smoothies could be a bit challenging for this blender, it needs a sufficient amount of liquids for this purpose otherwise, it will stall due to air pockets forming and had to be stopped to stir up content manually because it comes without any tampers or similar tools.

So, this machine hardly will prepare ice cream or frozen yogurts easily, however, the user can try to perform this task with extra efforts applied.

Soup/ hot ingredients: The KitchenAid Diamond 5-Speed machine will prepare hot soup from scratch because it does not heat any liquids via friction and it either does not have any heating elements. If you want to process already heated food then the user manual advice to cool the liquids before use if possible or when blending boil hot ingredients it requires to remove the cup from the insert in the middle of the lid and cover it with the towel to regulate the pressure the hot food may create inside of the container. Although it is not straightforward but seems clear that this machine is not really designed for blending hot liquids. Some consumers who used the machine for tasks like bulletproof coffee complain that the pitcher sealing gasket wearied out soon after using it for hot liquids. However, this machine is perfectly capable of pureeing cooled down ingredients for soup.

Pureeing: This KitchenAid Diamond 5-Speed Blender can successfully puree cooked and raw vegetables with some liquids added. It is able to make delicious hummus with a decent amount of liquid, however, it requires to scrap down the sides in between purée pulsing, but it came out well blended.

Chopping/food prep: Mayonnaise, salad dressings, mayonnaise, guacamole, sauces, and salsa is what this blender does the best. It is capable of emulsifying various dips however the thick ones like hummus with some efforts and enough liquids added. It is also perfect for veggies or nuts chopping. However, it is not powerful enough for chopping meat or fish.

Nut milk: The KitchenAid Diamond 5-Speed Blender will make decent nut milk, it easily pulverizes nut in liquids into homogeneous consistency.

Nut butter: This machine will be able to make nut butter from the soaked for few hours or roasted nuts (although not perfectly smooth) with stopping the machine a few times and mixing it with the spatula. Be prepared to add some oils and liquids also when processing your nut butter.

Grinding/milling: The KitchenAid Diamond 5-Speed Blender will grind the coffee, nuts, flax seeds, and grated cheese. The machine will also mill the oats and other soft grain but not suitable for making baking quality flour from the hard grains like wheat or rice.

Dough/batter: This machine is not designed to knead dough however it is perfectly capable of making delicious crepes or cookies batter.

Although KitchenAid Diamond 5-Speed is simple and not expensive blender there is a learning curve to learn how to use it most efficiently. For example, to blend the decent green smoothies you have to pulse it, then apply chop speed and puree at the end, it involves few steps, so in few minutes and few steps, you will be able to achieve a good result.

Speed Settings and Programs

The KitchenAid Diamond 5-Speed Blender is equipped with 8 buttons the power – Pulse, Ice Crush pre-set program, and 5-speed buttons – 1) stir, (2) mix, (3) chop, (4) puree, and (5) liquefy.

If the user wants to use the pulse then after choosing the pulsed it also requires selecting the exact pulse speed from 5 available ((1) stir, (2) mix, (3) chop, (4) puree, and (5) liquefy).

The Crush Ice button is pre-programmed to pulse at different speeds for 30 seconds. The control panel design for KitchenAid KSB1575 Dimond, KSB1570E, and KSB655 model differs slightly only by the shape of buttons and absolutely identical in functionality.

So, the blender’s choice of speed is quite good and allows the user to make a good array of nice recipes. All the buttons are slightly raised providing a little tactile feedback, so the user will never wonder if the button actually was pushed or not. Overall, the control panel looks very sleek and solid.

Ease of Using and Cleaning

To disassemble the blender the user has to rotate the pitcher counterclockwise to unlock and remove it. Some people complain that it is hard to disassemble but it happens not very often just with some units. It has a great, secure locking mechanism and very easy pour with no drips.

Cleaning: The user manual indicates that the KitchenAid Diamond 5-Speed Blender is dishwasher safe for easy cleaning up.

Base Unit and Motor Power

The interior build quality of the KitchenAid Diamond 5-Speed Blender seems great and heavy duty because it comes with the heavy die-cast base that looks sturdy and solid. However, it is equipped with quite low power motor of only 0.9HP (671 watts) what is typical for cheaper blenders under $50. Nevertheless, KitchenAid 5-speed blender definitely will outperform functionality of $50 machine and competes with the machines that cost under $100 and equipped with the power up to 1100 watts. Thus the motor has a good design although the power is rather low for this price range.

But the KitchenAid Diamond 5-Speed Blender motor construction still has one drawback. The gear that affixed to the bottom of the pitcher is made of plastic. The plastic gear is located at the place of high-speed spinning thus exposed to high loads and may disintegrate quickly what considerably reduces the durability of the machine.

      Hi Sherryl,
      The KitchenAid Dimond blender has an irremovable blade assembly. So you suppose to clean the jar without removing the blades. You can do it on the top rack of the dishwasher, self-cleaning way (fill half full with warm water, and add 1 or 2 drops of dishwashing liquid, put the lid on the pitcher, press the speed 1 setting, and run the Blender for 5 to 10 seconds, remove the pitcher and rinse with warm water). If you have trouble with clearing the food remains under the blades, use the kitchen brush.
      I hope it helps/
