I am so sorry. I see someone else posed this yesterday.

This Apex dishwasher belongs in someone's collection. May well be the only one in existence and never used to boot. What a find.

I had this model in my collection for several years and used it. It's a beautiful and vintage looking machine and the round window is super cool. Unfortunately this is probably the worst performing dishwasher I've ever used. It only has one wash and one rinse.

Does everyone know what the part I pointed to in red is?
