Fred's washed in the driveway & don't think anyone has leaned on it......it does complete the cycle. It's just that at 2 points in the process ......there's a sensation like a ....speedbump.
I had my son cycle it while I had the trim off & you see the whole motor flex when the bump sound occurs. Looks like a bracket that holds the motor has some rubber washers....maybe some flex is normal??
I might take the trim off of Wilma & look for any differences between the two actions.....
