My Dolphin Diagnostic 2002 robot died today.
It's only about 3 years old....I think it is the control board because it starts pumping, then moves a bit, then dies.So the pump and the motor are both able to work.
I bought the Dolphin because I got a good deal on it on ebay and my Aquabot was getting old and I abuse it.
Well, the Aquabot has needed a few minor plastic parts, but it is still going strong after about 10 years.
The lesson from this is to stick with the Aquabot brand. Forget about the Dolphin.
I went to the Maytronics site....still have no idea who or where to get the Dolphin serviced, but I doubt it will be worthwhile to fix.
