Check following point
 The fl ow 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 fi ltering performance is still satisfactory, the
cartridge's activated carbon may deteriorate rapidly due to
changes in the water quality or other factors so replace it
after using it for a year.
Check following point
 The water inside the outlet pipe is draining off .
 Are the acidic water and drain hoses bent or fl attened?
If water keeps running, it may cause malfunction. Also It can
not electrolysis correctly.

 Reduce the water fl ow at the faucet slowly until the message
is cleared.

 The build-up of calcium or other minerals inside the bypass

the solution for about 12 hours, rinse with water.
