Hi All, I own the Pentair Prowler 920 (= Dolphin Active 20 = Dolphin S200 = Dolphin Cayman = Dolphin Nautilus (2017 and Later) = Dolphin Proteus DX3 = Doheny's Saturn, etc). It's been a champ for several years, but now having issues.

When it turns on, the blue light on the cleaner flashes 5 times, it moves forward slightly, and then...nothing. It just stops. I took it apart and the motor seems to be seizing when it tries to go backwards, failing the test and shutting off. See below video.

I really need to get this guy back up and running. Any suggestions as to the fix?

There have been many posts about troubleshooting this model or its twins. Search for posts by @thebombardier. He hasn't been online in a while but used to be active. He is a service tech for robots.

Hopefully he’ll chime in here!

I’m thinking it’s the motor but having a hard time swallowing the idea of paying almost as much for the repair as the robot cost. It’s only 2 years old!
