Not to raise the dead thread, but I did get 4+ seasons with my Dolphin before it started taking lazy left turns due to many teeth wearing off the drive side track, which I replaced (should have just swapped them, Doh!) and made it another season before it started to just randomly quit after between 0 and 10 minutes for some reason. Took it apart (tracks & pulleys) no jams, impellers clear.
I assume the motor is overheating, or the power supply, and it's shutting down, but I doubt it's worth replacing since Maytronics is such a ripoff. I want to get another Dolphin since I have a complete set of spare parts, but hate to give them my business due to profit-hungry repair policy...
I do admit I leave it in the pool when I don't have time to clean the bag (no need to launder it btw, just lay it flat and hose it down, flip, repeat.) which increases wear and tare, but they are so rigid with parts and support....
