① Always assemble parts OFF of the juicer body.
Do not start assembly while the parts are on the juicer body. Our juicers are designed with safety mechanisms that may prevent parts from attaching or detaching correctly while on the base. Please place the chamber on a flat surface first and assemble all internal pieces and the hopper. Once the entire chamber set is fully put together, place it onto the juicer body.
② Check gaskets and seals
Ensure that all gaskets and silicone seals are correctly in place. If a gasket is missing or incorrectly fitted, the product may not assemble properly due to misalignment.

① Check the Gasket Assembly
Please check that both the juice cap seal and the juice outlet cover gasket are assembled correctly. If these seals are missing or installed incorrectly, juice may leak.② Inspect for Damage
Check that the gaskets are not torn, damaged, or deformed in any way. If any damage is found, please replace the part before use to ensure a proper seal.③ Secure the Juice Outlet Cover Latch
Please check that the juice outlet cover latch is properly secured and latched closed. If the cover is open or not tightly secured, juice may leak. (Applicable models: H400, H70FT)You can find video guides on how to assemble and disassemble gaskets for each model by searching for your product on the 'Care & Use' page. If you need to purchase replacement parts or if the leaking persists, please reach out to us via Contact us > General inquiries.
※ Please refer to the image below for the location of the juice outlet cover gasket. Note that the presence and shape of these gaskets may vary depending on your specific model. (The juice outlet cover gasket is specific to H400 and H70FT models.)

① Check the Gasket Assembly
Please check that the auger gasket or the chamber bowl gasket is installed correctly. If a seal is not installed or is assembled incorrectly, juice may leak onto the juicer body during operation.② Inspect for Damage
Check that the gaskets are not torn, damaged, or deformed in any way. If any damage is found, please replace the part before using the juicer to ensure proper function and safety.You can find video guides on how to assemble and disassemble gaskets for each model by searching for your product on the 'Care & Use' page. If you need to purchase replacement parts or if the leaking persists, please reach out to us via Contact us > General inquiries.
※ Please refer to the image below for the location of the chamber and auger gaskets. Note that the presence and shape of these gaskets may vary depending on your specific model. (e.g., H70ST Chamber Gasket, H400 Auger Gasket)

① Normal Operating Sound
A gentle, steady “humming” rotation sound is normal when the juicer is powered on. However, to protect the motor and components, please do not run the juicer "dry" (without ingredients) for longer than 7–10 seconds.② Ingredient-Related Noises
It is common to hear various sounds as ingredients are crushed and make contact with the juicer's parts. These are natural byproducts of the extraction process:- "Squeaking" sounds: Often occur when processing leafy vegetables like cabbage.
- "Rattling" or louder crushing sounds: Common with ingredients that have small seeds (like grapes) or firm, fibrous produce (like apples with peel, beets, carrots, and celery).
While these noises are often mistaken for motor issues, they are generally normal. However, if you hear excessively loud, sustained noises—especially without ingredients—or any sharp metallic sounds, please stop use immediately and reach out to us via Contact us > General inquiries.

① Natural Characteristics of Slow Squeezing
Hurom juicers operate at a low speed, and it is normal for a small amount of particles to mix into the juice through tiny gaps between parts. The juice may not be perfectly liquid like store-bought beverages. The amount of pulp can also vary depending on the freshness, harvest time, and storage conditions of the ingredients.② Leave the Juice Cap Open
It is helpful to keep the juice cap open while juicing. If you juice with the cap closed and then release the juice all at once, more particles collected inside the chamber may be discharged into your glass.③ Check the Juicing Gasket (Seal)
Ensure the juicing gasket (silicone seal) is assembled correctly. If the seal is not properly fitted, the pulp outlet can become blocked, causing pulp to mix into the juice.④ Clean the Pulp Outlet
Thoroughly clean the pulp outlet after each use. If residual pulp is not properly removed and dries up, it can cause pulp to flow into the juice during your next juicing session.⑤ Choose the Right Strainer (Strainer / pure line)
Please make sure to choose the appropriate strainer for your ingredients. Keep in mind that the holes in the Smoothie Strainer are larger than those in the Fine Strainer, which results in a thicker juice with more noticeable pulp.If you continue to experience an excessive amount of pulp after checking these steps, please reach out to us via Contact us > General inquiries.
