What to do if Tennant Scrubber vacuum fan will not turn on?

If the Tennant Scrubber's vacuum fan won't turn on, it might be because the recovery tank is full; drain the recovery tank. Another reason could be foam filling the recovery tank; empty the recovery tank. You may also need to use less detergent or change the type of detergent, or use a defoamer.
