"How could this solid tub washer in the AD have been metered filled?"
---Robert and others on this site have explained to me how solid tub washers, like Frigidaires, can have a metered fill. They exist, I've seen them.
"I could be wrong this, but I was once told that prior to GE manufacturing "takeover," the Hotpoint brand was supposedly more "high end." Fact or falacy?"
---I think that statement is referring to the belief that GE used Hotpoint as a "testing ground" for a lot of high end gimmicks and features before incorporating them into GE design. Remember that Hotpoint invented the Calrod heating unit that was why GE took the company over in the first place. My recollection is that Hotpoint appliances weren't quite as well engineered as GE's.
