Welcome to the world of owning a W?D and their reels.

Do the motors spin at all? If so, troubleshoot the connection between motor shaft and the plastic wheels them selves, metal screw tension vs plastic wheels was never a good design.

If the motors do not spin, they may be dirty. The motors do come apart and there is usually metal shaving that are inside, I would recommend trying to clean those as well. The shavings will be magnetized and want to stick to the inside of the motor. I'm sure others will chime in as well
