Dolphin Not Working

[holubec37]

I'm currently at work and do not have the specific model number, but my Dolphin doesn't work in the pool. When I start it, it goes forward then backwards then stops. When I take it out of the pool and turn it upside down, it appears to work properly (runs for a while in one direction before changing direction). Is there some sort of sensor that may be malfunctioning? Where would I begin troubleshooting the machine? All ideas are welcome.

Tried to find a thread that @JoyfulNoise posted in the last year on his unsuccessful attempts at repairing a robot, and his conclusions WRT robots...basically, 3-5 years is a good run. Maybe he will chime in...

Most probably water has leaked inside the motor. If you are DIY then have a look at this.

Pentair Warrior SE motor problem & Warranty replacement

I bought a new Pentair Warrior SE from Marina in Nov 2020 for my new fiberglass pool. I always keep it cleaned out and hanging in my equipment shed. It was a little sluggish over the winter while I kept my pool open but I just figured it was the cold water. It would just get stuck in the shallow...

I'm on my 2nd M600 in less than 2 years, they all failed with water intrusion to the motor and the cords cracking/falling apart. The first one was removed after every cleaning cycle and was sent back 10+ times, 2nd one is less than a year old and is on trip #5 for repair.
