I bought the 3900 kreepy krauly with my house over a year ago, it may be 4 or 8 years old. All worked fine. Now the 3900 has stopped. I have plenty ofwater pressure from pumps, reverse works well and drags 3900 across pool, there are no leaks in pipe joints.
The wheels of the unit do not turn when the unit is held just below the water. It appears that the 3900 internal turbine gear has a loose bearing. Has anyone had experience with this? Any advice will be well accepted.
