As the title says. Not sure when they stopped, as it was only tonight after a late night swim that my son asked me to put it on and I noticed they didn't go on. Worked fine last season. Functionality otherwise OK as far as I can tell. I can't find any documentation about the lights other than their diagnostic use. Thanks in advance.
 
So I contacted Maytronics who asked me to send them some pics of the unit and screenshots of the app. I went to take pics a couple of days later and I find the robot not working, with the power button in the base lit up red. A bunch of attempts at clearing it essentially did not work (other than once or twice for about a minute) so I brought it in to a dealer to diagnose it.
Yesterday I call and find out that they were able to run a full cycle. I inquired again regarding the nonfunctioning LED lights on the robot, as someone at Marina had mentioned to me that the board that powers those lights also has some other communication chips on it and that could be the issue. On hearing this the dealer said that if that's the case (no LEDs) it's probably the motor that needs to be replaced as water is getting inside (and that's why I had the initial symptoms of no lights).
Anyway, he recommended I take it home and try it out since it worked for them, and if it failed again the assumption would be a faulty motor. He posited that it maybe it worked for them because it sat and dried out for a number of days before trying. Also said no charge as they didn't actually do anything, so I very much appreciate the honesty. So my wife picked it up last night and I dropped it in the pool this morning, pressed the power button, and...
RED LIGHT!
Pressing it again would go back to green (standby), and again to blue for a few seconds then red. I tried a different outlet to be sure. I also tried taking it out of the pool and running it there. When I did that it seemed to go through the prestart check and rolled a couple of feet back and forth and turned, but then stopped and I got the error light again.
I'm going to try with a neighbor's power supply when I get home just for completion's sake, but assuming it doesn't work looks like it's heading back for a motor swap, unless anyone has any other ideas first.
Also, assuming it's an issue of water getting in where it shouldn't, is there a gasket or something else that I can look for that might be the source of the leak?
Thanks in advance
