Litter robot blue light flashes and on reset yellow light flashes quickly

[elektray]

On turning my Litter Robot on the blue Ready light flashes. On then pressing the reset button the yellow Cycling button flashes quickly.
I’ve checked and thoroughly cleaned the pinch sensor. They are clean and properly overlapping.
It now no longer operates. It doesn’t cycle and even after unplugging it, it no longer operates. The robot is only 10 months and it should be under warranty.

How can the issue be solved?

Hi @elektray,

The following troubleshooting should resolve the blue light blinking while the waste drawer is empty. Once resolved, the unit should consistently recognize when your cat visits and cycle accordingly.
To troubleshoot the blue blinking, let’s start by power cycling your unit:
1.) Leave your unit powered ON with the blue blinking light engaged & Unplug your power supply from the base
2.) Wait 10 seconds then plug the unit back in
3.) Allow the unit to complete a start‐up cycle. If the light is solid blue, the code has been successfully cleared. If the light is still blinking, let’s proceed with troubleshooting. Let’s empty the drawer if it has waste and reinstall the bag before proceeding.

Note: If you are using a dark colored bag, always tuck it into the tabs.

Let’s check your DFI Lenses for any obstructions:

1. Turn off the unit and Unplug the power from the base
2. Remove the Bonnet and the Globe
3. Inspect the top of the Base where the Globe usually rests. Is there any debris? Small amounts of litter are normal. Clean as needed.
4. Inside the waste opening there are two clear “Lenses” (left and right side). Ensure there is no debris on the Lenses. Sometimes litter can fall/splash onto them. ** To clean the lenses, we recommend wiping them off with a soft damp cloth and/or glass cleaner. Do not directly spray the Base or DFI Lenses. **
5. Replace the Globe and Bonnet. Reset the black key in the back of the unit into the pocket. 6. Plug the unit back in. If you turned the power off, you will need to power it on and press “cycle”. Once the cleaning cycle is complete, the unit should be at the Home position with a Solid Blue LED on.

Further Troubleshooting:

1. If the unit continues blinking blue, remove the waste drawer and press cycle.
2. Press reset 2x to abort the cycle and return the unit to home (it will level the litter).
3. If the unit goes to solid blue with the waste drawer removed, ensure there is nothing in the drawer blocking the lenses.
4. If the drawer is clear, your base needs to be repaired.

Let us know that you tried the full troubleshooting without results.

Hi again @elektray,

We see that you contacted also our Support Center regarding same topic so we can continue our communication there.

Just put in a ticket with the same issue on Litter-Robot forums. I have a LR3 with WiFi that I ordered May 30 2019. I cleaned the pinch detectors and they still touch. I tried resetting, still yellow flashing. I’m pretty sure I got a 2 or 3 year warranty added on. Please help.

Hi @SHilton0375 and welcome to our forum!

Have you bought it from RobotShop?

If so, please provide your order ID.

Thank you.

I bought a replacement DFI Kit to solve the issue described in many other threads on these forums, however it did NOT fix the problem, still have the persistent blue flashing light with the new part. What now?

Original unit was bought late 2016 - less than 2 years later it developed another issue whereby nothing could be fixed by troubleshooting so they asked me to send the base back, for a new one. The new one has been working these years but not without many hiccups, very finicky/sensitive, many times getting stuck halfway and needing to reset it. I have to mention that I have been extremely thorough in keeping the unit clean, replacing the bag usually long before the blue light starts even flashing, as I was relying on a 4 day interval reminder on my phone. I would very much like to know if there’s some way to completely deactivate this annoying drawer-full indicator and just have the machine work without that, as that surely would be better than having a €600 euro pile or useless plastic in my living room.

This machine is a great concept but destroyed by very poor engineering.
