Troubleshooting
NOTICE: Risk of property damage. If the toilet is plugged, turn off
the water supply before attempting to unplug it. The sensor can be
inadvertently activated while unplugging the toilet, resulting in an
overflow.
NOTE: For service parts information, visit your product page at
www.kohler.com/serviceparts.
Symptoms
1. The toilet is blocked.
2. Nothing happens when I
try to activate the sensor.
3. The module works, I hear a
beep, the wheel rotates, the
chain moves, but the toilet
does not flush.
4. The wheel contacts the
flush valve when flushing.
5. The toilet flushes, but the
flush is weak.
6. The sensor is not sensitive
enough (does not activate
when hand is within 1" (25
mm) - 2" (51 mm)).
7. The toilet flushes when I
am sitting on it.
