Help & Support

Hi!

I require your help regarding a problem I’m encountering.

**Light keeps changing red, yellow, blue. Tried to reset it , switch off and on and the issue remains.

I have a litter robot3 open air (refurbished)

Thank you so much in advance for your help!

If the Open Air unit cannot find Dump and/or Home position, the control panel will display 3 lights blinking. If you have recently disassembled your globe please advise.

Please remove the globe and check the black gear connected to the motor. When you press on the black gear with your finger, does it seem loose or free‐spinning? If so, please follow the instructions for tightening the set screw, here: http://litterrobot.kayako.com/Knowledgebase/Article/View/85/41/litter-robot--free-moving-gear-solution

When replacing the globe onto the base, make certain that the track around the outside of the globe is properly aligned into the groove on the base.

If the unit is plugged into a power strip, try plugging it directly into a wall. Sometimes the issue is caused by a fluctuating power supply, low voltage, or other power issues. If the globe is filled past the fill line remove litter so the fill line is exposed.

Can we ask the specifications on the adapter for the power supply you are using Correct Spec: 15VDC regulated adapter 400mA to 1,000mA.

[Note: If you are using a power supply with different specifications, the Litter‐Robot may appear to work properly; however, inadequate power can cause the unit to malfunction over time.]

  1. While powered on, unplug the unit from the back of the base.
  2. There is a pin in the jack where the small connector from the power supply is inserted. This pin should be split. Find something small and open it slightly if it is not.
  3. Plug in the power supply and let your unit cycle. What happens?

A blue solid light means the issue should be resolved.

Hello @Alyssadale,

Welcome to RobotShop community,

We are sorry to hear that you are having trouble with your Litter-Robot.

Have you disassembled the globe recently?

Did you make sure that the magnets are in place and attracting metal?

Sincerely,

I just did take apart the top and check the magnets they are in the right spots and attracting metal. Turned machine back on and it shows the yellow light on cycle but nothing happens and then the blue yellow red lights come back on.

Hello @Alyssadale,

Thank you for your reply.

This could be a motor problem or a malfunction from the circuit board.

Let’s check the motor first:

  • Turn the unit off.
  • Remove the bonnet and globe.
  • Put back the bonnet only.
  • Power on
  • Let the unit cycle for like 5 seconds, do you see the black gear rotating or not?
  • If not, please make sure that it’s not loose.

If it’s not loose and still not rotating then it’s a circuit board malfunction.

Let us know how it goes.

Sincerely,

It’s not loose and also not rotating. Is a circuit board malfunction possible to fix?

Hello @Alyssadale,

Thank you for checking.

In this case the circuit board will need to be replaced.

Please provide us with your order ID to check your warranty status.

Sincerely,

It’s not under warranty anymore. Is it available to purchase?

Hello @Alyssadale,

Sure, here’s the link for the circuit board:

And this is the video showing how to replace it:

Let us know how it went, or if you needed anything else.

If this doesnt fix the problem for whatever reason is the circuit board returnable?

Hey everybody!

I just tried many different ways to place these magnets. I originally had all of them placed the same direction. I got the red -> yellow -> blue flashing lights. With all of the magnets in the other same direction, the litter robot would stop quickly after it turns in the counterclockwise direction to return to the home position. Here is what works

ALL OF THE MAGNETS IN THE SAME DIRECTION… EXCEPT THE MAGNET AT THE VERY BOTTOM.

(The magnet that would sit in the 6 o’clock position if the globe was sitting in the upright position needs to be opposite from all of the other ones)

If your litter robot misses the dump position, and tries to continue turning after the dump position, That top magnet needs to be reversed. Place the other two magnets at the same polarity as that top magnet once you have it in the right direction. Then the very bottom one will be opposite from all of the other ones.

I have spent a lot of time trying to figure this out. I have not read this solution anywhere else, it was just trial and error for me. I wish litter robot would explain this for us on their website.
