Thanks for the tip. After getting the side cover off my Dolphin Diagnostic, I found that the hexagon adapter that connects the motor to the drive pulley was fractured where it connects to the motor. I ordered a new one for $20.50 from Inyopools.com. Thanks again.

Remove sideplate by: Curt
You must remove the sideplate to check for obstructions between the tread and drive gear. If this does not fix, then it's off to a service center for a new motor.
