I’m glad washing machines have returned to an agitator, it cleans the clothes much better. My old machine locked the lid once I hit the start button. I did not realize this appliance only lacks the lid during the sensing portion and during the spin it was difficult to find it, looking at the manual online . Once I googled the question, I found the answer then used the keyword to find it mentioned, really buried, in the 56 page manual. You should include a quick start up guide that mentions some of the basics.  My startup instructions were basically a commercial for various laundry products, oh yes, and connect the hose.
