    Doheny Discovey Issue- Unit starts then stops immediately

    I am having an issue with my Doheny Discovery / Dolphin S200, which I wanted to see if anyone has experienced.

    The unit is just less than a year old. Recently it stopped working properly. When started from the power supply, it will start forward 1-2' for about 5-10 seconds and then just stop. I did some troubleshooting:
    -I just opened up the impeller looking for hair and debris, including removing the fan blade where it enters the metal shaft, all looked clear.
    -Checked all side and bottom ports, those look clear.
    -The basket is clean
    -The tracks appear to be on properly and can be rotated by hand with the unit off, with what feels like normal resistance.
    -I took the unit out of the water, unplugged the power supply for an extended period, and checked the cord for damage. All looked fine.

    Anyone else experience this issue or have any other troubleshooting suggestions?

    It has been a great cleaner so far, much better than the older generation Dolphins we had. It has a 2 year warranty, so I guess that is the next step in the process if I can't get it working.

    Thanks!

    Just took everything apart again to see if I missed something, plus took both rubber tracks off, checked for obstructions and reinstalled- no luck, still same behavior.

    There are other threads with similar symptoms. All Dolphins have a startup sequence and yours seems to be detecting an error and stopping. You checked all the obvious issues so it points to a possible motor issue. You canít repair the motors, if they go bad they are simply swapped out with new ones. Start the warranty repair process, thatís your best bet.

    Can you turn the impeller by hand?

    Yes, the impeller and directional pivot both move by hand. The unit moves in the start up routine, so as others have suggested, probably some motor issue. Waiting to hear back from Maytonics.

    Sent the unit back to the Maytronics service center- 2 days and $50 to Fedex from CA to AZ. They dropped a new motor in it and shipped out the same day it was received. Two days after that it was back in the pool and working normally.
