I've had a Polaris P93 pool robot cleaner for about 5 years. Haven't had any issues until recently. Here is what I'm experiencing.
1) When the robot is dry out of water, I am able to start it up. The fan blows upon startup. Obviously with it not being in the water errors out. But the point here is that the fan starts up.
2) When I submerge it under water the fan pushes the robot a foot then errors out (flashing led's).
3) Once it's been submerged for a while it fan no longer starts up. I have to wait until it drys out OR leave the head unit unplugged (discharged) for it to start up again.
I don't have schematics but I do know the following:
1) I've replaced the basket with a new basket. It's a regular basket and not fine mesh.
1) I checked continuity on all 3 pins of the cable (end to end) and there are no breaks.
2) I checked voltage coming out of the head unit (28 volts) which seems to be correct.
3) I took apart the robot and measured the voltage at the end of the cable that plugs into the motor, 28 volts.
So at this point I think it may be the motor but not sure. Has anyone else experience this problem?
Thanks
