Symptom
When the water flow is
reduced at the faucet during
use, the display suddenly
changes to "Cartridge life"
"Disconnect power plug
and re-connect it" message
appears on the display
The "U25" or "U26" code is
not cleared even after the
cartridge is replaced
The "U26" code does
not appear even after
the time (approx. 1 year)

the faucet has been
turned off
No water comes out
when the Alkaline
Ionizer is used at the

a place other than the
selected spout
82
Cause and remedial action
This happens when the water flow is reduced too much or the
flow is diminished due to a change in the water pressure.
When using the Alkaline Ionizer at the "Alkaline 4 (Strongly
Alkaline)", "Weak Acidic" or "Purified Water" setting, press
the water quality selector button again, turn on the faucet,
and adjust the flow.
The flow has diminished because of cartridge clogging or
some other reason.
Disconnect the power plug and then re-connect it. If
operation is continued and the "U25" code appears,
replace the cartridge.
Have you forgotten to reset the cartridge life?
Refer to step 3 in the procedure of "Replacing the
cartridge", and reset the cartridge life.
Did you reset the cartridge life with the power plug disconnected?
Connect the power plug, and then reset the cartridge life.
Has the Alkaline Ionizer seen less use so that the total run-
through volume of water serving as the guideline for cartridge
replacement (12,000 liters) has not been reached yet?
This is not a malfunction. Check the cartridge life display.
Although the filtering performance is still satisfactory, the
cartridge's activated charcoal may deteriorate rapidly due
to changes in the water quality or other factors so replace
it after using it for a year.
Cause and remedial action
The water inside the Alkaline Ionizer is draining off.
This is not a malfunction.
Are the acidic water and drain hoses bent or flattened?
Straighten out the hoses.
Has the "Reduce flow" appeared on the LCD display?
Reduce the water flow at the faucet slowly until the
message is cleared.
Are the acidic water and drain hoses bent or flattened?
Straighten out the hoses.
Have the acidic water and drain hoses been connected
correctly?
Check the connection of the hoses to the acidic water stand.
Has the "Reduce flow" appeared on the LCD display?
Reduce the water flow at the faucet slowly until the
message is cleared.
The build-up of calcium or other minerals inside the bypass
selector may be to blame.
Obtain some citric acid from a pharmacy, dissolve 50 g in
one liter of water, and after immersing the bypass selector
in the solution for about 12 hours, rinse with water.
