Dolphin Diagnostic Parts: Cable Testing and Replacement

Maytronics Dolphin Diagnostic User's Manual (opens new window)


Forget about replacing the pump and motor. Unless you have a spare robot for parts, internal maytronics parts are impossible to get. Your dealer will send your robot out for repair.

Prevention is the best remedy. Avoid operating your Maytronics cleaner under any conditions that will clog the bag and prevent water circulation around the motor housing. Heat will destroy the electrical components inside the case.

Re-coil the cable after every use starting at the robot and working the twists outward to the plug. Chances are...if your cable will not float straight and is always being sucked into the robot, that cable has most likely been stored in a piled twisted mess. Recoiling the cable takes all of 30 seconds and saves hours of aggravation.

I have several photos including a photo of the inside of the motor housing.



Maytronics Dolphin Drive Track Removal

1. Remove the bottom plate with bag.

2. With the machine upside down, remove the screws holding the debris shield and remove the shield.

3. Remove the screws holding the side plate.

4. Gently pry off the sideplate. It may need much persuasion due to dirt buildup on the sideplate pegs that slide into the body.

Be sure to clean dirt, debris and other contaminants from the parts that slide into each other.

5. Remove the drive track. The system is direct drive with the drive gear in the center. Drive gear and pulleys slide off the spindles.


FOR THE CURIOUS I opened a motor compartment to satisfy the question of what is in it. No instructions are included to put it back together because parts are unavailable.

The motor assembly inside the robot body is held in place by screws accessible once the sideplates are removed. Inside the box is the pump, drive motor, circuit board and a counterweight to offset the buoyancy of the air filled box.

Opening this box creates the challenge of airtight reassembly. The gasket must be re-used and I suggest a good coating of silicone to keep it pliable and easier to slide into position.

Notice the motors have little direct cooling contact with the water.
