TV Sitcom Washing Machines--and more!
Oh, man, you're bringing back more than a few memories about washing machines!
Here are a few that I remember: The first "Bewitched" episodes (before they moved to 1164 Morning Glory Circle) did feature an old flat-top Maytag automatic in the rental house Darrin and Samantha had...but when Chevrolet came on board as an alternate sponsor with Quaker Oats, the Stephens kitchen boasted TOL Frigidaire appliances, including a Flair range and fridge with a push-button door latch. In 1969 (between seasons), a fire swept the Screen Gems studios and destroyed the "Bewitched" set--except for, of all things, Elizabeth Montgomery's dressing room! And since Chevrolet dropped "Bewitched" after the 1968-69 season, the producers replaced the Frigidaire appliances with those made by other makers (Maytag washer and dryer, for example), and a gas stove (one episode has Samantha saying, when Larry Tate asked what happened to Darrin, "the pilot light's gone out in the stove...he went to fix it.")
"Hazel" started its first season with RCA Whirlpool appliances, but when Ford bought Philco (including Philco-Bendix washers and dryers with that distinctive glass window!) in late 1961, they cobbled up an episode where Missy (Dorothy Baxter) and Hazel conspired to convince George to remodel the kitchen (including a shot of an electric knife sawing through a milk carton on the cramped worktop)--and voila! Philco appliances appeared!
When GE came on board as co-sponsor with Ralston-Purina for "Leave it to Beaver" circa 1960-61, Ward and June moved to the new home and a glamorous new kitchen full of TOL GE appliances (including the washing machine that oversudsed spectacularly when Beaver and Whitey did the wash!)
Interesting note on Doris Day and "The Thrill of it All": You are right that the Happy Detergent commercials have her surrounded by RCA Whirlpool Mark XII automatics--but in a kitchen scene where she's talking about fixing a roast for dinner, she and James Garner are standing in front of a built-in Frigidaire Custom Imperial oven!
