The wheels on my 6-week-old Polaris 360 stopped spinning like others in this forum. The tail is still whipping and water is flowing strongly from the jet drives. If I manually spin the single wheel myself, the other 2 wheels will freely spin. I placed a straw over the 3 jets underneath and blasted water through each with a garden hose. After this, the sweep worked nicely for about 10 minutes, but then the wheels stopped again. I actually tried to repeat the process again, this time blasting each jet even more thoroughly. Again, the sweep started up well with the wheels spinning, but again the wheels stopped after a few minutes. Thanks for the help so far ... any advice how I can keep these wheels moving?
