Dolphin Power Supply Not Working, Blinking Light, or Tripping the GFCI

Smart Pool & Spa • Dolphin Robotic Pool Cleaner

The poolside power supply will not switch on, its indicator blinks an error pattern, it beeps, it shuts off a few seconds after starting, or it trips the GFCI outlet every time. This is the external power brick failing or protecting itself, which is different from the robot powering on normally but sitting still on the floor (that is a drive problem). The Dolphin power supply is the box that stays poolside and converts AC to the low-voltage DC that runs down the floating cable to the robot.

Dolphin Robotic Pool Cleaner Not Moving or Stuck in One Spot

Smart Pool & Spa • Dolphin Robotic Pool Cleaner

Your Dolphin robotic pool cleaner drops into the water, the power supply indicator shows it's running, but the robot sits on the pool floor without moving or moves a few inches and stops. The drive motor on one or both sides may not be engaging, or the tracks/wheels are spinning but not gripping the pool surface. On Dolphin robots, the drive motors are located inside each side panel of the unit — one motor per side drives the rubber tracks (on tracked models like the Nautilus CC Plus) or the rear wheel assembly (on wheeled models like the S300). The power supply is the large brick that sits poolside and converts AC power to the low-voltage DC that runs through the floating cable to the robot.

MyDolphin Plus App Not Connecting to Dolphin Robot

Smart Pool & Spa • Dolphin Robotic Pool Cleaner

The MyDolphin Plus app cannot find or connect to the Dolphin robotic pool cleaner. The app shows "Searching for robot" indefinitely or displays a connection error. WiFi-enabled Dolphin models connect to the app via the pool cleaner's built-in WiFi module, which communicates through the power supply unit. Both the power supply and the robot must be powered on and within range for the app to connect.

Dolphin Robotic Pool Cleaner Starts Then Stops or Shuts Off Mid-Cycle

Smart Pool & Spa • Dolphin Robotic Pool Cleaner

The Dolphin powers on and runs for a few minutes, then stops out in the pool, sometimes with a red light on the power supply. This is different from a unit that never powers on and from one that powers on but never drives; a cleaner that starts then quits is almost always hitting an overload from a jam, an overheating motor, or a blockage that trips the protection.

Dolphin Robotic Cleaner Cable Keeps Tangling and Twisting

Smart Pool & Spa • Dolphin Robotic Pool Cleaner

The Dolphin floating cable tangles into tight knots or twists into a coil during cleaning cycles, causing the robot to stop moving or get stuck in one area of the pool. Cable tangling is the most common Dolphin complaint and usually results from the cable developing memory coils from storage or the anti-tangle swivel wearing out.

Dolphin Robotic Pool Cleaner Not Climbing Walls or Cleaning Floor Only

Smart Pool & Spa • Dolphin Robotic Pool Cleaner

The Dolphin cleans the floor fine but never leaves it, or it starts up a wall, loses grip a foot or two up, and slides back down. Wall climbing on a Dolphin depends on suction, brush grip, and a small rubber flap that builds the climbing force, so when any one of those is off the robot stays on the bottom.

Dolphin Pool Cleaner Not Picking Up Debris or Leaves

Smart Pool & Spa • Dolphin Robotic Pool Cleaner

The Dolphin robotic cleaner runs its full cycle but leaves debris, leaves, or fine dirt on the pool floor and walls. The filter basket or cartridge may be full, damaged, or incorrectly seated, or the impeller that creates suction may be clogged or worn.
