I have problems with my Dolphin T25

What to do if your Dolphin T25 is not working?

If your Dolphin T25 pool cleaner is not working, start by checking that there is voltage in the power socket in the wall. Ensure the power supply is plugged in and turned ON, and that the power cable is securely connected all the way 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 T25 pool cleaner still not move or be moving in circles, verify that the floating cable is securely connected into the power supply outlet. Unplug the power supply, open the impeller cover, and check that nothing is trapped in the impeller or blocking the tracks or wheels. Clean the filter basket/canister, remove any debris from the impeller house or cover, and ensure the power supply is positioned correctly to allow the cleaner to reach all areas of the pool. Make sure there is enough slack in the floating cable for the cleaner to reach all parts of the pool.

Following these troubleshooting steps should help resolve most issues with the Dolphin T25 pool cleaner. If the problem persists, consult the user manual or contact customer support for further assistance.
