Flushing
● Is the shutoff valve fully open?
● Is the water fi lter clogged?
➞Clean the filter.
● Is the water supply to the toilet disrupted by other running water fi xtures?
➞Cease using other fixtures and then flush the toilet.
● Are the fl ush and light fl ush buttons being used correctly?
 
Flush (for solid waste): Up to 10 m of toilet paper (single)
  Light fl ush (for liquid waste): Up to 3 m of toilet paper (single)
● Flushing may be diffi cult depending the consistency of the waste material.
➞Flush the toilet again. If the bowl unit is not cleansed with a flushing,
remove the stains with a brush or similar instrument.
● When the tank is fi lling, you cannot fl ush the toilet.
➞Once the main display "Power" LEDs are lit and the tank fills up with water,
flush the toilet.
● Oil and other hard-to-see grime may stick to the bowl unit surface.
➞Clean the bowl with (non-abrasive) neutral toilet detergent.
● Is "AUTO OPEN/CLOSE (LID)" set to "OFF"? ➞ Set to "ON".
● Does the body sensor have diffi culty detecting?
➞Remove any dirt that is on the body sensor.
● Even when set to "ON", AUTO OPEN/CLOSE (LID) is not performed for
about 15 seconds after the toilet seat or toilet lid is closed.
 
When the toilet lid is closed by hand
(To make the NEOREST more user-friendly, a time interval is set from when
the lid is closed to when it will open next.)
➞ Leave the bathroom, and then after 15 seconds or more, approach the bowl unit.
● Detection may be diffi cult when the room temperature exceeds 30°C, such as
in the summertime. ➞ Open and close manually.
● Is "AUTO OPEN WAITING TIME" set to 30s or 90s?
● Is a toilet seat or lid cover installed?
➞Remove any covers.
● Is "AUTO OPEN/CLOSE (LID)" set to "OFF"? ➞ Set to "ON".
● When you do not sit on the toilet seat, or when the time spent sitting on the
toilet seat or standing in front of it is 6 seconds or less, the toilet seat and
toilet lid close after about 5 minutes.
● If they do not close automatically even though "AUTO OPEN/CLOSE (LID) "
is set to "ON", the body sensor may be detecting incorrectly.
➞If there is a reflective object in front, such as a mirror or glass, move the
reflective object or use a curtain or other object to block it.
