Question about Smart Pool Inc Dolphin Diagnostic Automatic Pool Cleaner Ne250

2 Answers

Dolphin Commander goes forward 2' then back 2' then stops.

Just bought a home with pool and Dolphin Commander(think simlar to Diagnostic) came with it. Previous owner had for maybe 4 or 5 years and worked fine. Now I put it in the pool for first time and it will turn on, but it only goes about 2 feet forward then 2 feet back then that is it. The vacuum fan doesn't turn on at all and I checked for debris but it seems perfectly clean. Any help is greatly appreciated!
Thanks

    Thanks! When you say expensive, how much are we talking about? I'm just not sure if worthwhile or not.

I just ran into the same problem and what I did was take off the top yellow straner that exposes the fan. Then when it stops turn fan by hand(that kick starts the fan) and then it will continue to do the cycle

The impeller motor is likely worn out. New motor units are expensive but less so than a whole new unit. You can send it to us in Michigan at www.arrowmotor.net or find a closer service center using www.maytronicsus.com Good luck.

    Contact our Dolphin repair coordinator, Gloria, at gloria@arrowmotor.net. Include your unit serial number which can be found inside the outer case, just under the filter bag/bottom lid.



    She can quote you the motor installation.

Tip

Your Dolphin pool cleaner wont start up...


A common problem, especially with 'newer' Maytronics Dolphin brand pool cleaners is that you put the unit in the pool, or even try to turn it on after a cleaning cycle while it is still in the pool, and to that point it has worked fine. You turn the power supply on and nothing happens. You turn it off and back on and still nothing. You leave it, even over night, same thing. What do you do?

While I cannot tell you why it does this (we have a theory but can not confirm it) what usually works is to follow these steps...

1) Unplug everything. Unplug the power supply from the outlet and the Dolphin from the power supply.

2) Let the whole thing sit a couple of minutes (we want to allow any capacitors to discharge).

3) Be sure the Dolphin is out of the water and sitting upside-down on a level surface (Tracks pointing skyward).

4) Reconnect the Dolphin to the power supply and the power supply to the outlet.

5) With the Dolphin still out of the water, perform a self-test. Simply turn on the Dolphin. Within about 15 seconds it should begin to move. The tracks will spin in both directions with and without the impeller motor running at the same time. It is not unusual for the tracks to rotate at different speeds during this test. The test will last for 30 - 45 seconds or so. If it goes on indefinitely, turn it off and contact us for further direction.

6) Assuming the unit has now worked to this point, you should be able to put it back in the water and it will return to normal operation from this point on.

If it still won't run; it runs a few moments and quits the self-test; or runs continuously, contact us thru the Dolphin service form along the bottom of our home page at www.arrowpools.net.

Dolphin Interactive pool cleaner stops running


If the dolphin is falling backward when it meets the water line, there is an easy fix. The automatic pool cleaners often have this problem. The easiest solution is to remove the handle floats and attach an 8 oz weight to the bottom inlet cover.

Dolphin diagnotic pool cleaner just stopped working.Son took it out of water and wrapped cord up and almost pulled wires out of plug that goes into the motor mount.


The wires in the pool cleaner probably did disconnect from the motor. You might not be able to see the disconnection, but i would guess this is the problem since you already know your son made the mistake. You are probably going to have to take it to a service center so an electrician can reconnect your wires.
