Hey all - I have a Polaris P825 that is going into it's 5th functional year. Last fall I had a problem with it not moving when on; since then I've replaced the motor, the brush rollers, brush scrubbers, tracks, and exhaust vents - basically everything but the cord. Once replaced, the cleaner has been working great.
This week, however, I started having a new problem - I put the robot in the water, turn on the control unit, start the cleaning cycle, and within seconds the unit turns off. It's doing that 100% of the time now. Does anyone know why the unit (control unit itself) would just turn off? Is that a built-in shut down if a fault/short is detected? I can't believe I have a problem with the robot itself since it's pretty much rebuilt. I've done a quick scan of the cord from the control unit to the robot and don't see any obvious issues (just some normal wear & tear). Also note, the unit is plugged into a GFCI outlet, and it's not tripping.
Any advice/help is appreciated - I really don't want to buy a new robot, especially after rebuilding this one!
