Hottop Coffee Roaster
If the roaster is functioning normally in all other ways, but the drum is not turning, here are some steps to take to help diagnose the problem.
If the drum is not turning, or turns hesitantly or intermittently, wait until the roaster has completely cooled before attempting to diagnose the problem. Once cooled, remove the drum, and while the drum is out of the machine, plug the machine in and begin a roast as you normally would. Look into the roaster and see if the Motor Drive in the center of the rear wall is turning, indicated by the "B" in the photo below:
IF NO: Contact your dealer or Hottop USA for further diagnosis and possible Drum Motor replacement.
If the drive pin indicated by the red arrow in the above photo is missing, the Roasting Drum needs to be replaced.
