Symptom Check Measures to take
All operations
abnormally
occurred.
• Is the main water being supplied actively? Check the main water supply valve.
• Is the power connected?
Check if the power cord plug is plugged
into a 120 v~ 60 Hz wall outlet.
• Is water overflowing or leaking?
In this case, please contact the service
center.
• Does this occur frequently?
In this case, please contact the service
center.
Beeped and
Cleaning LED
blinked while
the water is
extracted.
• Is Inlet water high or low flow
rate?
In this case, please control inlet flux by
adjusting the inlet adapter valve.
Cleaning LED
blinked while
the water is
not extracted.
• Do you check errors of the inlet
valve and the sensor flux?
In this case, after the ionized water
is extracted, the normal state can be
recovered. But if this error frequently
occur, please contact the service center.
Beeped when
the water is
extracted and
automatically
stopped.
• Do you check disconnection of
electrolyzer?
In case that this problem is consistently
occurred, please contact the service
center.
Water leaks.
• Does the water leak when ionized water is
extracted?
Close the water supply valve and
contact the service center.
The operation
automatically
stops when
extracting ionized
water.
• Has the extraction time exceeded the preset
time?
To prevent water overflowing by
mistake, ionized water extraction is
automatically stopped when a preset
time has passed.
- Ionized alkaline water, filtered water
: Stops after 2 minutes of continuous
extraction
- Weak acidic ionized water: Stops after
2 minutes of continuous extraction.
A white
substance settles
at the bottom
when ionic water
is left over.
• Has the calcium ion in the water combined with
the carbonic acid in the water?
This is caused by the calcium mineral
that melts in the water has been
extracted, depending on the main
water quality.
Although drinking the water is safe, if
this symptom continues, ask for after-
sales service to protect the product.
Noise is
generated inside
the product
when extracting
ionized water.
• Do you hear the sound of air bubbles and water
flowing when extracting ionized water?
The noise is generated when ionized
water is generated by the electrolyzer
and this is normal.
• For filter replacement: (213) 386-9900 / (213) 480-1600, For after-sales service: (213) 386-9900 /
