I'm having problems with my Polaris 280. The wheels stop turning every few minutes. I can pick up the unit and spin the wheels manually and it will work for a while but the wheels eventually will stop moving and the unit will creep from the water coming out of the back of the unit until it hits a wall.
The reverse valve (is that the correct term?) seems to be working fine. The unit will back-up every few minutes.
The filter seems clean and water does not appear to be flowing from the pressure release value near the wall connector. I did notice a small leak of water around one of the hose connectors just above the reverse value when I picked up the hose. The unit is three years old. The pump appears to be working properly--and the unit will move normally for a bit after I manually turn the wheels. I'm guessing the gears are worn. Any ideas would be appreciated.
