Drawer full on two units

Help & Support Domestic Robots

Hello,

I have 3 Litter-Robot 3 units and two of them, with only a couple of weeks of difference, have had the same problem. The drawer is always full (blue light blinking). I have cleaned both just in case it was that (including the sensors, because some time ago it was that the problem), I have had both disconnected some hours… but the problem still remains. If I want a cycle to be done, I have to press the reset button, and then, after one cycle, the blink starts again (even with no drawer…)

Thanks.

Hello @marcgp ,

Welcome back to RobotShop community.

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

Please try to clean the 2 green circuit boards of the DFI sensor with isopropyl alcohol and a Q-Tip to remove any rust or dust from the tiny pins of the chips located on these boards.

Here’s a video to help you locate the boards:

If you find this too complicated for you, you can send us the robots for repair under the warranty.

Awaiting your reply.

Sincerely,

Hello Ebram,

Sorry for taking so long. One of the two robots is at my mother’s home, and I could not check it until today. Both cleaned, and on both the problem remains…

Thanks.

Hello @marcgp,

Thank you for your reply.

In this case, we can send you 2 new DFI sensors to fix the problems.

We will also need to see the 3 pairs of contact pins shown in the following videos:
Anti-Pinch Pins:

Bonnet’s Pin:

Base’s Pin:

No need to take them out of the robot, we only need to see them from the outside.

Please provide us with your shipping address and phone number.

Awaiting your reply.

Sincerely,

Hello @marcgp ,

Thank you for your reply.

The contact pins between the bonnet and the base in both of the robots will need to be replaced along with the DFI sensor.

You need to clean the pins and DFI sensor regularly to avoid having such issues again.

We will forward you now to our replacement department to carry on with the process.

You will be contacted shortly with further details about the shipping.

Have a lovely day, stay safe.

Sincerely,
