Trouble Shooting Guide
The Function Display
Panel does not come on.
A power plug is not property
inserted, or it is inserted into a
faulty outlet.
The fuse is blown.
The fuse is not inserted properly.

Abnormal condition
Resolution
Cause(s)
Abnormal condition
Properly insert power plug into
a correctly functioning power
outlet
Replace the fuse. A spare fuse
is included in your reagent kit.
(3A / 250V fuse)
The Function Display Panel /
display indicators do not
come on even after turning
the tap on.
Faulty PCB
(Printed Circuit Board)
Immediately unplug the unit
and contact your dealer to
arrange service.
pH test shows alkaline water
color as neutral (7) while
acidic water color gets
yellow (6). This is normal
if initial pH is 6.5
Faulty or evaporated reagent:
alkaline / acidity are always
produced in inverse proportion.
Therefore, showing an acidic
color means inversely that
alkaline water has to be
generated from the unit.
Lack of alkaline color can
result from a chemical
reaction where carbonic
acid in water evaporates
some test reagent elements.
Test pH value on level
3 or 4 water;
replace reagent.
Power supply is suddenly
cut off while operating the
unit.
Elevated level of salt in the
water or high TDS; extended
operation at high pH;
sudden flux in electrical
current. In these cases your
machine will shut down
automatically to protect the
electrodes and circuitry.
Wait - the unit will become
operational again after about
one hour. Your ionizer has a
safety mechanism built-in to
protect the electrodes and
circuitry. This mechanism will
shut the ionizer down
automatically. This mechanism
protects the unit from overuse
or excessive electric current.
Low output of alkaline water
from the unit.
Filter is clogged. Premature
clogging may be caused by
sudden drop in water quality and
an influx of sediment or other
contaminants, which stress
the filter.
Low pressure in your household
plumbing.
The input hose is bent, kinked or
otherwise restricted.
Replace your filter.
Clean Pre-filter
Ensure water supply valves are
fully open. The water pressure
in house may be too low.
Straighten the bent hose.
Strange smell from
Alkaline water.
Expired filter from ordinary use
or premature clogging due to
flux in water quality.
Sudden flux in water quality with
elevated level of Choline
(not Chlorine). Elevated Choline
levels are observed in some
areas during summer months.
These levels fall within safe
drinking water standards, yet
will cause a reaction with ionized
water causing a unique smell.
Replace your filter.
Select lower pH level (1-2).
If still present, filter replacement
may be necessary.
Water appears milkish;
white snow like particles
in the bottom of your glass.
You have high hardness (calcium
primarily) in your water. The white
is extracted CaCO3 (Calcium
carbonate). After Co2 in water is
bonded with Ca where elevated
levels of CO3 exist in your water.
In water where elevated levels of
CO3 exist, what you see after
ionization is Co2 in the water
bonded with Ca.
This is calcium! It is not only
harmless, but actually good for
you. Remember the ionizer
separates and condenses the
alkaline minerals and this is what
you are seeing. You can lower
the setting (1-2) and reduce
this effect. Typically this only
occurs in hard water areas.
At first no smell, but then
smell from the alkaline
water about one hour after.
Your water bottle or receptacle
is foul and needs cleaning.
Contamination mixes with
alkaline water when filling your
bottle. Expired filter.
Clean your bottle or receptacle.
Try selecting lower pH level
(1~2). Replace your filter.
Water leakage from the
filter cartridge housing.
Filter not installed correctly
into filter housing.
Remove your filter and reinstall it
properly following the filter
replacement instructions.
Increase the quantity of source
water inflow.
No acid water flow from the
acidic output port.
Acidic output hose is bent,
kinked or otherwise restricted.
Straighten the bent hose;
increase water flow from supply.
Poor / Irregular pH
Production at levels
1,2,3 and 4
Either overly hard or soft water
(excess or lack of minerals
in water)
Adjust the voltage output, please
refer to page 23 in this manual
