Hi, I’m Scott from Alpha Power Cleaners and today we’re going to be looking at the F7 fault on a Tenant M20 scrubber dryer. The F7 fault relates to the recovery tank being full. With draining your recovery tank, you know it’s empty. Inside there is an electronic float which nine times out of 10 gets a buildup of debris around it and stops it from functioning. At this point you want to take some fresh water, rinse it off, wipe it, make sure it’s moving freely and then you should be good to go. If the problem persists, call Alpha Power Cleaners.
