Troubleshooting (continued)
■ Is this a malfunction? (continued)
Symptom
Very little or no water
is discharged from
the Alkaline Ionizer
When water is run
through the Alkaline
Ionizer, the water that
comes out is warm
The buzzer does
not beep even when
using the "Acidic
Water" setting
The water produced
by the Alkaline
Ionizer has an odor or
unpleasant taste or is
turbid
The pH level of the
water produced by
the Alkaline Ionizer is
not within the rough
pH level range
The pH level of acidic
water is neutral
Water comes out
from the bottom of
the main unit

Cause and remedial action
Is the water pressure too low?
Open up the faucet all the way.
Has the flow at the faucet been reduced too much?
Open up the faucet.
Is the filter of the bypass selector clogged?
If it is, clean the filter.
Has the cartridge been installed properly?
If it has not, install it properly.
Has the water supply been cut off?
Wait until the water supply is restored.
Is the water supply hose bent or flattened?
If it is, straighten it out.
Has the Cartridge Replacement Lamp lit?
If it has, replace the cartridge.
When water starts to run through the Alkaline Ionizer, water
which was kept at room temperature while no water was
flowing to the Alkaline Ionizer or water warmed by the heat
inside the Alkaline Ionizer may come out.
This is not a malfunction. Allow the water to keep flowing
to the Alkaline Ionizer.
Has "OFF" been set for the "Acidic buzzer" setting?
If so, set "ON" for "Acidic buzzer".
The ability of the cartridge to remove odors, unpleasant
tastes and turbidity has deteriorated.
Replace the cartridge.
The pH level may be a little high when a new cartridge is
used (for the first week or so).
This is not a malfunction. Measure the pH level again
after a week.
If the pH level of acidic water is 6.5 or so, it may not be
possible to distinguish it from the pH 7 level (neutral) in the
pH Chart.
Test the water coming out of the drain hose while using
the "Acidic Water" setting, and if it is 10 to 11, it means
that the pH level for acidic water is 6.5 or so.
Depending on the temperature conditions, water formed from
condensation may collect inside the main unit.
This is not a malfunction.
