How do I get my pool cleaner to communicate? Some how the robot and control box are not communicating

I am having this same problem at the moment. I keep getting that Dang error in the app!!!

It sounds like you’re dealing with a communication issue between the robot and the control box—which usually means there’s a problem with the data connection, especially if you’re using a Wi-Fi–enabled (IoT) model like the Nautilus CC Supreme.

All app-compatible Dolphin models use a three-wire blue cable:

• Two wires handle power,
• The third wire handles data communication (like manual drive, changing modes, etc.).

That’s why you might still be able to power it on from the app, but things like manual drive or mode changes fail—those need that third wire to work properly.

To reset everything:

Step-by-step reset:

1. Unplug your Wi-Fi router, wait 15 seconds, and plug it back in.
2. Unplug the Power Supply from the outlet, wait 30 seconds, then plug it back in.
3. Disconnect the blue cable from the Power Supply, power it on, then wait 30 seconds and reconnect the blue cable—make sure it’s seated properly and the cable isn’t damaged.
4. Delete and reinstall the MyDolphin™ Plus app. When prompted, make sure to allow all permissions (especially Location and Bluetooth).
5. Confirm your Wi-Fi is on a 2.4GHz network (Dolphin robots don’t support 5GHz).

If that doesn’t resolve it, there may be a physical issue with the cable or connector—especially the data wire—and support can help test that further.

Derek,

Thanks for your response, I will attempt to reset everything using your instructions.

Quick question for you: with these fancy IoT models...are you still able to use them without the smart features and/or app?? I had a CC plus non wifi before the supreme and just pressed a button on the Power Supply. In other words, with the Supreme should I be able to just press the button on the Power Supply and have it start without even opening/using the app??

I followed the reset steps and still nothing. I'm seeing the lights on the power supply come up so I don't think that's the problem. It's either the swivel cord (I did have an issue with this a few months ago where one of the 3 pins inside the swivel connector was not springing back up, but I cleaned it up and it was working at that time so not sure if something else went wrong) or the robot itself.

Short of me getting another swivel cable to run tests to isolate the problem are there any other sort of "tests" anyone can provide tips on?

If I got a 2 wire cable and connected it would it still work (obviously without any of the data communications stuff working)? I'm so frustrated by this supposedly more advance device. I just want to go back to when I had my non-wifi CC Plus and it just worked. I don't care about all the fancy Crud in an app if I can't get it to communicate correctly.
