Just stick something in the lid switch hole. It's simple.
Frankly, if this one fills to the top row of holes, I'd keep it and look for another machine for your Dad. Find him a nice inexpensive WP or something.
You'll have fun watching the indexing tub, that's for sure.
I'm so glad you have a video camera! Can't wait to see the straight-vane agitator in action. I have a sneaking suspicion it will produce a more vigorous washing action than my dual-action job. Mine suffers from deriving all the agitation power from four skinny little fins at the very bottom of the agitator. It really whips up a storm for small and medium loads, but once the tub is filled to capacity with water and clothes, there just isn't enough 'action' in my opinion.
With your straight-vane, there's wash action the whole length of the agitator, which makes more sense. Makes me wonder if they changed the agitator design to the dual-action because it actually increases rollover, or if they changed it just because everyone expects to see a dual-action in a washer these days. The cleaning score in Consumer Reports for the Frigidaire TL'er decreased once they changed to the d/a agitator...
