Considering we’ve received a huge response on our Litter-Robot II Basic Troubleshooting Guide, we’ve decided to help our customers further by creating this advanced troubleshooting guide. This guide will help you with :
Opening up the Litter-Robot II
Testing the power supply
Verifying the circuit board connections
Verifying the safety line connections
Verifying the motor connections
Verifying the Hall effect sensor
Opening up the Litter-Robot II
To open the Litter-Robot II base, you will need a Torx T20 screwdrive and a 5/16″ socket with a ratchet.
First, remove the 7 torx screws around the base.

Remove the Screws
With the ratchet, remove the 5/16″ nut which attaches the motor to the base.

Spot the Motor Inside the Base

Remove the Motor Nut
You can now split the 2 parts of the base.

Open the Litter-Robot Base
Testing the power supply
To test the power supply, you simply need a voltmeter. Connect one probe to the barrel and one probe inside the tip. If you measure ~15V or more, then your power supply is working.

Testing Power Supply
Verifying the circuit board connections
Pull on the front panel to reveal the circuit board.

Locate the Front Panel

Pull on the Front Panel
You should see numbers on the sensors connector and the white tab on the power connector should be toward the circuit board plastic panel.

Verify the Circuit Board Connections
Verifying the safety line connections
To reach the safety line connections, first you have to remove the black cover inside the Litter-Robot.

Remove the Black Cover
You should see two black wires going to a switch or a metal bracket. Verify if they are correctly in place and connected.

Verify the Safety Line Connections
Verifying the motor connections
To reach the motor connections, first you must remove the black cover inside the Litter-Robot.

Remove the Black Cover
You should see the following connections:
- White wire from the motor to brown wire from the Litter-Robot harness
- Red wire from the motor to green wire from the Litter-Robot harness

Spot the Motor Connections
Verify if they are properly connected and if the connectors are attached to their respective wires. The wires may be corroded and you may need either a new harness or Litter-Robot replacement motor.

Verify the Motor Connections
Verifying the Hall effect sensor
The hall effect sensor is located near the motor.

Locate the Hall Effect Sensor

Hall Effect Sensor Close-up
A white stripe is visible if it’s installed on the right side. You should verify if it’s correctly in place.

Verify If the Hall Effect is Installed Correctly
