Blue light blinking - Litter robot 3

Hi,

I need help with my litter robot 3 please.
The blue light is blinking although the waste drawer is empty. The other buttons do not react to pushing except the on/of one.
I cleaned the sensors and all robot is clean.

Please advise.

Many thanks,
Maria

Hello @Mariagav ,

Thank you for your reply.

According to your order number, the robot is no longer under warranty.

If the cleaning of the DFI sensor didn’t fix the issue, we recommend replacing it so you can order a new one from this link:

We also recommend replacing the 3 sets of pins so you can order new ones from these links:

The following videos will show you how to replace these parts:

Hi Ebram,

This looks like rather guessing and replacing all that can be replaced to get it working again. All those contacts are like new on the robot, no any bit of rust on them, why to replace them?
It all started with the robot not doing the clean cycle properly: when it reached the point where the waste was dropped and was supposed to turn back it went forward again and after a hump it stoped. Why would it do that?

Many thanks,
Maria

Hello @Mariagav ,

Thank you for your reply.

It’s recommended to replace the pins every 6-12 months depending on their state so we usually recommend replacing them or at least having them at home to avoid having to pay shipping again for such small parts.

The error that you have described is called Anti-Pinch fault and it’s related to the Anti-Pinch pins.

As for the blue blinking light, it’s related to the DFI sensor.

Let us know if you need further assistance.

Hi Ebram,

Thank you for the information you sent me.

I still have a problem: the DFI in my litter robot 3 is longer and different than the one received with my order. Because of that it won’t be possible to replace them

Can you please advise if it is a wrong part I received? Please see the picture of my robot’s DFI.

Many thanks,

Maria

Hello @Mariagav ,

Thank you for your reply.

The DFI sensor that you have received is the new version and it looks different but it has the exact plastic brackets so you can easily install them the same way as the older sensor:
DFI v2

Let us know if you need further assistance.

Sincerely,

Hi Ebram,

I only received the sensor, the clear plastic brackets didn’t come with it. The sensor doesn’t fit the old brackets.

Regards,
Maria

Hello @Mariagav ,

Thank you for your reply.

Are you sure that the plastic brackets weren’t included?

Please provide us with your order number.

Awaiting your reply.
