What to do if your Dolphin S300 is not working?

If your Dolphin S300 pool cleaner is not working, start by ensuring there is voltage in the power socket in the wall. Check that the power supply is plugged in and turned ON, and that the black power cable is securely connected into the power supply inlet. If these steps do not resolve the issue, turn the power supply OFF, wait 30 seconds, and then turn it back ON.

Should the Dolphin S300 pool cleaner still not move or if the red light on the power supply is on, check that the blue floating cable is securely connected into the power supply. Unplug the power supply, open the impeller cover, and ensure nothing is trapped in the impeller or blocking the tracks or wheels. If the pool cleaner is out of water, place it back into the water to resume normal operation.

Following these troubleshooting steps should help resolve most issues with the Dolphin S300 pool cleaner. If the problem persists, consult the user manual or contact customer support for further assistance.
