The first thing I did with the original DRIVE was to take it apart and test those contractors, but now we have the same problem with the brand new DRIVE.
Is this the only error you're getting? I would clear the errors and get a list of all of them. F-1 is the most recent. If there are several, get the list in the order they occurred and get them posted. I adjusted several of these units before going into the service department.
