TROUBLESHOOTING Q&A

When there is no power to the juicer:

Check if the power cord is properly plugged in.

Check if the drum lid and the juicing bowl are

properly assembled.

Check if the top-set and the body are properly

assembled.

Juicer will not operate if parts are not

assembled properly.

Low juice yield:

Different ingredients hold different amounts of

fluid that will yield different amounts of juice.

If the ingredients are not fresh, they may

contain reduced amount of fluid, which will
yield less juice. Sock ingredients in cold water
for about 30 min prior to juicing for the best
result.

Check if the compression silicone is firmly

inserted.

If the ingredient itself has low water content,

it may help to soak it in water before juicing.

If juicing ingredients with small seeds, after a

few servings, it may reduce the juice yield.
For best result, disassemble and wash the top-
set in between juicing.

If there is seed residue on the bottom of the

strainer, this can affect juicer performance and
the overall juice yield.

There is too much pulp in the juice:

To reduce the fine pulp, clean the top-set

frequently and extract the pulp.

Use a mesh strainer and put the juice through

it to collect the unwanted pulp.

If the strainer and the screw are damaged

and affecting the juicer’s performance, it is
recommended the parts be replaced.

*The lifetime of each part may vary depending
on length and method of use and ingredients
extracted.

The drum lid will not close:

Make sure the juicing screw is pushed all the

way in to the strainer in order for the drum lid
to close properly.

If the juicing screw is not properly in position,

the drum lid may not close.

Odd noise from the juicer:

Check if the parts are assembled correctly.

Try reassembling the parts and listen for the
odd noise.

Do not start the juicer unless there are

ingredients and/or liquid in it.

Operating the juicer without ingredients can

cause damage to the screw.

If the juicer is operated without ingredients or

liquid, the noise level can increase and also can
lead to damage.

The friction noise from the juicing screw and

the strainer will disappear when ingredients
are inserted into the juicer.

If the noise occurs when ingredients are

  inserted into the juicer, check the size of the
  ingredients. Do not insert anything over 1 inch
  in thickness.

Depending on the type of ingredients,

the dimensions can be smaller.

The noise can occur if the juicer is operated on

an uneven or slanted surface. Place the juicer

on a horizontally flat surface when operating.

The extracted pulp is very moist:

During the very beginning of extraction,

the pulp can be more moist.

Depending on the ingredient’s condition,

  the extracted pulp can be affected; especially
  when the ingredient is not fresh, the juice can
  be extracted with the pulp.

During operation, the juicing bowl shakes.

The juicing screw and the strainer are set up to

crush and squeeze the ingredients. It is normal
for the juicing screw and the strainer to vibrate.

If the ingredient contains strong fiber,

the vibration from the top-set may be stronger.

During juicing, the juicer stopped:

Check the power cord and make sure it is

plugged in correctly.

Check that all the parts are correctly assembled.

If too many ingredients are inserted at one time,

this can cause the juicer to stop.

When the juicer stops because there are too

  many ingredients inserted in it, press the
  REVERSE - OFF - FORWARD button in this order,
  switching back and forth 2 to 3 times.

The reverse setting will push the ingredients up,

and the forward setting will pull the ingredients
down.

After using more than 30 minutes, if the juicer

  stops due to the overload protection, let the
  juicer cool for 30 minutes to 1 hour before
  juicing again.

If there are hard seeds within the ingredients,

remove them before juicing. Hard seeds can
damage the juicer.

Layers of separation in the juice:

Depending on the density of the ingredients, the

    extracted juice may show layers of different juices.
    It is different from separation due to oxidation
    caused by juicing with a high-speed juicer.

The drum lid is stuck:

After juicing, let the juicer operate for another

30 seconds to extract the remaining pulp.

If there is too much pulp in the top-set, this can cause

  the drum lid to not open. In this situation, press
  the REVERSE-OFF-FORWARD button in the order,
  switching back and forth 2 to 3 times. Then place both
  hands on the drum lid and firmly press down while
  simultaneously turning the drum lid to open.

Pour water down the feeding tube to rinse out

the insides and then try opening the drum lid.

Juice dripping down the body:

If the compression silicone on the bottom of

the juicing bowl is not plugged in correctly,
the juice may seep out on to the juicer body.
Before assembling the parts, check and make sure
the compression silicone is plugged in correctly.

Is it possible to juice ingredients with

tough

fiber?

Ingredients like celery or ginger contain long

fibers that may wrap around the juicing screw
and affect the juicer’s performance. When
juicing fibrous ingredients, do not collect more
than 1 lb. of juice. After collecting this quantity
or less, clean the top-set completely before
juicing again.

Discoloration of the plastic parts:

After juicing, if the juicer is not cleaned right

    away, the remaining pulp inside the top-set
    can dry up which can make disassembling and
    cleaning hard. This can also affect the juicer’s
performance and color.

Ingredients that are rich in carotenoids such

    as carrots and spinach may dye plastic parts.
    When the parts are dyed with carotenoids, rub
    vegetable oil in to the dyed areas and use mild
detergent to clean.

Vegetable oil should only be used during

clean-up for parts that are discolored. Do not

use vegetable oil on the juicing screw or the

strainer. If vegetable oil or oil from animal fat

gets on the juicing screw or the strainer, this

can affect the juicer’s performance and may

result in damaged parts.

The silicone pieces on the top-set can be

detached to be thoroughly cleaned.

Using for purposes other than juicing:

This juicer is designed to juice ingredients like

fruits and vegetables.
