My Polaris 9550 sport has not worked properly for about 9 months now. It starts a cleaning cycle ok, but after one or two times of climbing the wall, reversing down, and turning to start another forward swath, it stalls out for about 5 seconds, then starts driving backwards until it goes up the wall and flips over, landing on its top. After about 30 seconds upside down, it rights itself, then maybe operates correctly for a pass or two, but then inevitably stalls out after turning and drives in reverse again. The robot can still clean when it drives forward, but when it goes in reverse, it does not clean anything and just wears the gears down and makes the cleaning cycle very prolonged and inefficient. I am pretty disappointed as this is my second major issue with the 9550 since I first purchased it 3 years ago. Because Zodiac had sent me a replacement unit due to the first major issue 2 years ago, I have an old 9550 full of spare parts. So, here is my systematic approach to troubleshooting this unwarranted and unwanted reversing issue, one thing at a time:
1.) Swapped the caddy control module. Didn't fix the issue.
2.) Disassembled unit, cleaned out trapped leaves, and changed the wheel gears (some were quite worn down). Didn't fix the issue.
3.) Disassembled unit, removed motor, opened motor housing, and swapped the circuit board. Didn't fix the issue.
4.) Disassembled unit and swapped out the floating cable. Didn't fix the issue.
I am at a loss! What else could it be? I thought that the issue was related to some kind of mixed signal the unit was getting where the unit thought it had been climbing a wall and was putting itself in reverse to come down the wall or that it was getting a false signal from the remote control telling it to move backwards. In either of those cases, I thought that swapping the circuit board, cable, and control module would have corrected it...but nope. Any ideas of what it could be and what else to try?
