Hi guys, I was wondering : About what year have the dishwashers started to 'migrate' from propellers to spray arms and pump systems ? Which brand was the first to do it ? Thanks ! | ||

I'm amazed at how comparitively short the cycles were on dishwashers from the 50's, 60's and even the early 70's. Many machines' normal cycles push the 2-hour envelope these days. Given that, today's dishwashers have no excuse not to clean better than their vintage counterparts, whose cycles were barely a third as long. I use the 50-minute Speed Clean cycle almost all the time on my new Frigidaire. Consumer Reports didn't have anything good to say about it, but I find it does a great job of cleaning a full load. (They tested the model below mine, and I think it's called the Turbo Boost cycle on that machine.) I have very soft water, so that may make a difference, and I don't let the load sit overnight before washing, as they do in their tests. We had a Westinghouse built-in when I was a kid. In fact, I believe it was installed the year I was born (1959). I think the whole unit pulled out and it was loaded from the top. I don't have as many vivid memories about our dishwasher as I do our washing machine---probably because I could look into the washer and see all the action. | ||

RCA Whirlpool Dishwashers.
I remember a relative had an RCA Whirlpool DW in her house she bought in 68/69. The timer dial was on the right side, and looked exactly like a telephone dial (hook to stop the finger and all.) Like a phone, you stuck your finger in the hole that corresponded to the cycle you wanted and "Dialed it" clockwise till the finger-stop stopped you. It then rotated backwards partially like a phone. The tub was blue, and perhaps like the GE "Perma-tuff" was made of a plastic coating over something (maybe metal) I dont remember the spray arm system (alas, they WERE spray arms), but I do rememer a rectagular stainless steel fine filter in the bottom that fed into a courser filter. It was a removable-to-clean cup/glass trap. [Looks like a present-day BOSCH] This area was to the (right?) side of the machine and the rectangular heating element surrounded it. The steam vent was upper left of the door as one looks at it, similar to a modern Whirlpool. The detergent cup had TWO closed square cups and the opening of it was done by a round thingy, like a wine cork with two metal ....Ida know.... hooks? It turned one way and the prewash cup opened, then later the other way to open the second cup. (Kitchen Aid had two closed cups for a while too, I think) The silverware baskets ran from all-the-way left to right in the center of the lower dish rack. this left room for deep stuff (bowls) in the front and rear. The machine started by draining (HELLO TODAYS ENGINEERS!!!)then there was also a "purge" in the beginning to rid the lines of cold water. The fill solenoid vale and the drain were open simulataneously for a few second at first. (Safe to do when the first phase was a rinse, and the detergent was "hiden" in a closed cup) Like a GE and also like a Kitchen Aid (when it was by Hobart, and definitely before it was Whirlpool..)the motor ran continuously 'till the "dry" segment and the water and fill valves opened and closed as needed. And just to be totally cool it did not have a latch like GE or D&M, but rather a "U" shaped handle with three sides and two 90 degree angles. UP to open, DOWN to lock. It doubled as a towel rack!! Ah... memory lane! | ||

Fills would whoosh
YES! Now I recall why the sounds were so interesting to me... @ the time I was 5 or 6 years of age!!! and the only reference point I had was Mom's Sears Kenmore (D&M) that had motor pauses between phases, (it paused to change the direction of the motor... one way to recirculate, the other way to pump out and drain.) I was surprised with my portable WP dishwasher (bought in '90/91) that had pauses between phases, but also started recirculating the water before the fill was complete.. a hybrid! I am really surprised, though, that now with computer chips there is NO CREATIVITY /THOUGHT given to what can now be done. For example, have certain programmable, but fixed options (that stay in emmory) and everyday choosable options. Here is what I mean. Have an option to have a metered fill, rather than a timed fill. (there are floats already in machines!!!!)People with low water pressure will benefit from being able to have a machine or get decent results from their machine. (and "time" these fills overall for flood protection) Have a selectable 2nd rinse.. like on a clothing washer. Since Uncle Sam ("US govt." for our international friends' benefit) tests machines based on their "Normal" cycle. This will make their machine show a better effeciency. Also default to a cool dry (non-heated dry) and give us a 0,5,10,15 minute dry option. Add a neon light advising when to add bleach. (the rinse between the washes comes to mind)to be able to sanitize without running for hours and hours using heat. Great if someone is ill. [IMHO one of the original "purposes" and appeals of a machine was to prevent cross-contamination with young children.] This is ideal too because kiddie loads tend to have alot of plastic items that may not like heat. Add a glass-ware cycle..... drain first... wash and rinse. Great for cocktail parties or even (for the total "Mrs. Van de Kamp's" out there)... to prepare for a cocktail party by giving your seldom used stuff a spiff-up. Add a "purge" programmable option if water heater is far from DW... to get the cold water out of the lines before starting. Or better yet have 2 closed detergent cups and do three really quick soap-less prewashes to get rid of the cold water. Why waste it? Then move into a regular cycle. Oh,and how about a "QUICK" wash for compulsive pre-rinsers and for during a party. Etc. | ||
