Your Dolphin Power Supply & Timer

If you can remedy a power supply or timer issue on your own, more power to you! Here’s some targeted advice for doing just that. For added safety, follow these “Pool & Spa Safety Tips” informed by the ESFi or Electrical Safety Foundation Int’l.:

•   Comply w/applicable electrical codes.
•   Use GFCI hard-wired or portable outlets.
•   DO NOT handle electrical devices when wet.
•   Keep plugs near water activity covered and dry.

Q. Can we power our Dolphin residential pool cleaner or commercial pool cleaner by using an extension cord?

A. For your safety DO NOT USE an extension cord with your Dolphin pool cleaner. Extension cords present a fire hazard, reduce pool safety levels and impair equipment performance. Instead, plug your robot vacuum directly into a properly-rated outlet and make sure it’s at least 10 ft. away from any water source.

If your Dolphin is having trouble reaching the far ends of your private swimming pool, hire a qualified electrician. He or she may be able to relocate an existing GFCI outlet for safe operation. If not, have them install one in a spot that ensures your Dolphin will easily reach from pool surface to pool floor.

Q. Why isn’t our power supply working?

A. First, check the outlet. Then, plug in another device like a hair dryer. If that won’t work either, reset the outlet’s GFI switch. Still no luck? Switch outlets. If the other items work but your robot doesn’t, take it to your local Maytronics Dealer for power supply testing.

Q. The power supply works fine—but my Dolphin won’t seem to budge. Why is that?

A. If your pool robot doesn’t move at all, there may be a power cable error. (Was it run over by aliens?) If your Dolphin moves a few feet but then stops, it could be there’s a drive train or impeller blockage to blame so have a closer look:

•   Inspect the impeller itself.
•   Inspect all tracks and brushes.
•   Remove any debris that’s visible.
•   Gently rotate the brushes by hand.
•   Do they move back and forth easily?

It’s normal to feel some resistance but not much. If those steps don’t help—or if you feel/hear clicking or popping—there may be a hidden obstruction. Take your Dolphin to an authorized dealer for close inspection and testing. Bring your original receipt with you, too. Replacement parts may be covered under warranty.

Q. Why do only some power supply features work?

A. Some features are specific to certain robot pool cleaner models: programmable timer, fast-cleaning mode, delayed start. Search for your model at to see which features are built-in.

Your MyDolphin App & Bluetooth®

Innovation is great, ain’t it? The answers to the questions below will help you understand remote control operation via your Dolphin pool cleaning robot’s MyDolphin app and Bluetooth® control.

Use Bluetooth to “set and forget” select robots from anywhere with WiFi access. (Pictured: Bluetooth network image)

Use Bluetooth® to “set and forget” select robot models from anywhere with WiFi access.

Q. Why can’t I get the MyDolphin App or Bluetooth® to work?

A. The app is specific to robots with an Advanced Power Supply which are Bluetooth®-equipped. At type in your model name or # to display a list of features. If these come standard, you can “set and forget” your robot from anywhere as long as you have WiFi access.

Q. Our MyDolphin App displays an error message. What do I do?

A. If an error message pops up, try restarting the app. It’s best if your WiFi connection is 3G or 4G. Too, take the following steps anytime you connect (or reconnect) your Dolphin to the app:

•   With your Dolphin “Off,” open its casing.
•   Note your unit’s Serial # (near the barcode).
•   Close the unit casing, turn it “On” and let it run.
•   After 1+ min., connect your smartphone to WiFi.
•   Pair via Bluetooth® to your Dolphin—not a neighbor’s.

You’ll know the app is connected if the power supply buttons are overridden in “Disable” mode.
