Pool cleaner cleaned half the pool then stopped. I couldn't get it to move more than an inch before it would shut down again. The power supply was good, so I decided to disassemble it. I saw this mess when I opened it up.
I blew it out with compressed air and got a new desiccant bag and bench tested the motors. I think the desiccant mess shorted the electronics just enough to cause it to shut down. Hopefully the robot is back up and running for a while. I thought I would share for anyone else with a dead Dolphin. Wear and tear wise I think this could go another decade if the power supply lasts.

I don't see any corrosion on the circuit card (doesn't mean there isn't some damage I don't see), so hopefully I caught it early enough and don't spring a leak into the motor box now. I did add re-lube the seals before reassembly.
