TROUBLESHOOTING
Problem Possible Cause Solution
Mode indicator
light blinks
slowly (once
per second).
Litter box is in LOW
POWER mode –
indicates low battery
power and the rake
function is disabled.
Check to make sure the
litter box is plugged into a
working outlet.
Replace the batteries as
instructed in CARE AND
CLEANING (Note: bat-
tery power is meant to
be used during an outage
only; it does not provide
enough power to run the
unit continuously.)
Mode indicator
light blinks
quickly (twice
per second);
rake moves
continuously.
Litter box is in FAULT
mode. The rake has
encountered a
blockage – either in
front of or behind the
rake. There may also
be loose litter piled
behind the rake that’s
preventing it from
returning to the home
position. As a result, the
rake cannot complete its
normal cycle. (Note: The
rake will automatically
cycle 5 times to attempt
to clear the blockage; if
unsuccessful, the LED
light will blink and the
rake will return to the
home position.)
Turn the on/off button
off and unplug the unit.
Use the scoop & rake
cleaner to clear any
clumps or blockages that
are preventing the rake
from completing its cycle,
as well as to level off the
litter level, so the level
is below the MAX line
throughout the tray. Once
blockages are removed,
plug in and turn the on/
off button on. If the unit
still does not function
correctly, make sure the
limit switches (located on
the front and rear right
side of the rake track) are
not stuck – both should
be out (R).
