Product Overview
The KitchenAid K400 KSB4027PA is a full-size countertop blender in the K400 product family. It combines a 56-ounce blending jar with five manually selectable speeds, a pulse function, three preset blending programs, and a dedicated cleaning cycle. The standard preset programs cover ice crushing, icy drinks, and smoothies.
The blender uses a ribbed jar, an asymmetric stainless-steel blade system, and Intelli-Speed motor control. The motor-control system adjusts operation in response to the contents of the jar, while the Soft Start function begins at a lower speed before increasing toward the selected setting. These systems are intended to improve ingredient circulation and reduce splashing during startup.
The K400 is designed for household preparation of smoothies, frozen drinks, sauces, dips, purees, soups, spreads, and similar blended foods. Additional compatible containers were also developed for smaller portions and individual servings. The KSB4027PA version uses the standard KSB4027 blender platform and is identified separately by its complete model suffix.

Product Identifier Summary
Model Number

Common Uses
The K400 is intended for general household blending and food preparation. Its variable speeds and programmed cycles support both liquid mixtures and recipes containing solid or frozen ingredients.
- Fruit and vegetable smoothies
- Milkshakes and blended drinks
- Crushed ice
- Frozen beverages
- Pureed fruits and vegetables
- Soups and sauces
- Dips and spreads
- Nut-based mixtures
- Dressings and marinades
- Small-volume recipes when compatible accessory jars are installed
Maintenance and Care
The blender includes a dedicated cleaning cycle. The documented procedure calls for filling approximately half of the blender jar with warm water, adding one or two drops of dishwashing liquid, running the cleaning program, and then rinsing and drying the jar.
The blender should be unplugged before manual cleaning. The motor base and power cord should be wiped with a warm, damp cloth and then dried with a soft cloth. The motor base and cord should not be immersed in water, and abrasive cleaners or scouring pads should be avoided.
The standard blender jar is dishwasher safe according to the manufacturer’s care instructions. The manual permits the blender jar to be washed on the bottom rack, while several smaller accessories and lids are designated for the top rack.
Before storage, removable components should be clean and thoroughly dry. The blender should be stored where the cord and jar are not exposed to unnecessary moisture, impact, or excessive heat.
Safety Information
- Connect the blender to a grounded three-prong electrical outlet.
- Do not remove the grounding prong or use an electrical adapter.
- Do not operate the blender with an extension cord.
- Unplug the blender before removing the jar after use and before manual cleaning.
- Wait until the blender has completely stopped before removing the lid or jar.
- Do not immerse the motor base or power cord in water or other liquids.
- Keep hands and utensils away from moving blades during operation.
- Use appropriate supervision when the appliance is operated around children.
- Move the appliance by supporting the blender base rather than lifting it by the jar or jar handle.
The manufacturer also specifies a grounded electrical connection and warns against adapters and extension cords because improper connection can create an electrical-shock or fire hazard.

Frequently Asked Questions
How can I identify this KitchenAid K400 blender?
Check the product’s model label for the complete designation KSB4027PA. The full model number is more precise than identifying the appliance only as a K400 because several K400 configurations exist.
What size batches is the standard jar intended to handle?
The standard jar is designed for full-size blender recipes. Smaller compatible containers are available for recipes that do not require the main jar’s capacity.
Does the K400 have to be operated only with preset programs?
No. Users can select manual variable speeds or pulse operation when a preset cycle does not match the desired preparation method.
Can the blender be used for hot ingredients?
The manufacturer’s manual permits hot ingredients in the main blender jar with specific operating precautions. It instructs users to begin at a low speed and gradually increase the speed when blending hot liquids. Hot liquids should not be processed in the optional Personal Jar or Small Batch Jar.
Why does the blender stop after several minutes?
During manual variable-speed operation, the K400 automatically stops after three minutes. This is normal programmed behavior rather than necessarily indicating a malfunction.
What happens if the motor becomes overloaded?
The blender incorporates an automatic shutdown response for an overload or jam. The appliance should be unplugged before the jar is removed and ingredients are rearranged or divided into smaller batches.
Can the blender jar go in a dishwasher?
Yes. Manufacturer care instructions identify the main blender jar as dishwasher safe and permit it to be placed on the bottom rack.
Is the motor base dishwasher safe?
No. The powered base should be unplugged and cleaned with a damp cloth rather than immersed in water or placed in a dishwasher.
Does the blender have a self-cleaning function?
It has a programmed Clean cycle intended to circulate warm water and a small amount of dishwashing liquid through the jar. The jar should be rinsed and dried after the cycle.
Is a personal blending cup included with KSB4027PA?
The standard configuration does not list a personal jar among its basic included components. Personal and small-batch containers are associated with separate accessory kits or other K400 bundles.
Does the K400 require installation?
No permanent installation is required. It is a countertop appliance that should be placed on a clean, dry, stable surface near an appropriate grounded electrical outlet.
What warranty documentation applies to the K400?
The manufacturer’s K400-series manual documents a five-year full warranty from the original purchase date for covered household use in the 50 United States, District of Columbia, Puerto Rico, and Canada. Warranty exclusions and regional terms apply.
Why is the complete model number important when ordering parts?
K400 models have been sold in multiple configurations and bundles. Using the complete model designation helps distinguish the correct configuration when researching replacement jars, lids, accessories, manuals, and service information.
Buying Considerations
The KSB4027PA is a full-size blender rather than a compact personal blender. Available counter space, jar capacity, cleaning requirements, noise tolerance, and intended batch sizes are therefore relevant factors when comparing it with other blender formats.
The standard configuration uses a large BPA-free jar rather than a glass jar. Users specifically seeking glass construction should distinguish the standard KSB4027 configuration from K400 variants or accessories that may use a different container.
The blender has both manual controls and automated programs. Users who primarily want simple one-touch operation may focus on the preset functions, while recipes requiring closer texture control can use the variable-speed dial and pulse function.
Optional K400 accessories can change the blender’s practical use for smaller recipes. Those accessories should be identified by their compatible model numbers rather than assumed to fit solely because they are described as blender accessories.
Customer Feedback Summary
This section summarizes recurring themes found in publicly available customer feedback. These observations are subjective reports and should not be treated as verified technical specifications.
Positive feedback commonly describes effective smoothie preparation, ice crushing, straightforward controls, and a substantial motor base. The cleaning program is also frequently mentioned as a convenient way to remove ordinary residue after blending. Some users report that the variable-speed control provides useful flexibility when moving between liquid recipes and thicker mixtures.
Reported limitations include noticeable operating noise at higher speeds and a preference among some customers for a glass container rather than the standard plastic jar. Some feedback also describes difficulty removing thick mixtures from around the fixed blade area.
A smaller group of long-term reports describes problems involving jar seals, leakage, blade assemblies, or bearing-related wear. These reports do not establish that every unit will develop the same issue, but they are recurring durability concerns found in public owner feedback.
