Talk:Dishwasher

From Wikipedia, the free encyclopedia

I haven't completely read this article yet, but I found the history section lacking. Surely, some company can be linked to the first commercially available home dishwashing machine. I believe that such a machine came to be during north america's 1950's post ww-ii industrial boom (but I could be wrong). Many companies acquired vast manufacturing experience and needed to put their talents to use.

When I moved here (USA-Virginia) in 1976, we had a Frigidaire stove and a Hotpoint refrigerator but I simply cannot remember the brand of the dishwasher, so I am curious as what was the first well-known dishwasher brand (here in the US).

For example: Air Conditioner -- Carrier Microwave Oven -- Amana (RadarRange) TV -- RCA

I hope that someone can fill in the history section of this article. It would be greatly appreciated, I'm sure.

[edit] Integrated dishwashers?

What is the difference between an integrated dishwasher and the other kind? I'm looking to buy a dishwasher and they are classed into "freestanding", "semi-integrated" and "fully integrated".


Freestanding can be installed anywhere. Integrated can be fitted with a panel to match the kitchen and installed in a kitchen cupboard. Fully integrated are concealed behind a kitchen furniture door. Here is a book you can read. [1] --WikiCats 14:41, 17 April 2006 (UTC)

[edit] Dishwasher as a person

Is there a more sophisticated word to represent a person who washes dishes for a living?

How about "scullion"? AdeMiami

[edit] Brands

I removed the high-end, mid-end, and low-end brand rankings from the page. It was confusing, incomplete, and subject to opinion. I do not think that ranking dishwashers would ever meet WP:NPOV and WP:V. Bige1977 02:58, 13 February 2006 (UTC)

Some description of brands and different features would be useful in the encyclopedia (without a ranking). The dishwasher itself has to be made by one company or another. --WikiCats 09:28, 14 February 2006 (UTC)

[edit] External link suggestion

This link leads to a series of articles on the topic of diagnosing and repairing a dishwasher, written for the do-it-yourselfer. It is more detailed and thorough than the current external links.

Because I am affiliated with the site, I am adding it as suggested external link rather than adding it myself.

[edit] etching of glassware

I read the the hazing of glassware is caused by the etching effect of phorphous in the dishwasher detergent. That paragraph has been replaced with something else without an explanation. Can someone verify the phorsphous contents in dishwasher detergent and its effects on glassware? Kowloonese 21:58, 21 June 2006 (UTC)

If you can cite a reference to phosphates corroding glassware, then feel free to add it. If you read it, then I assume you can reference it? WLD 08:02, 22 June 2006 (UTC)

[edit] Thank you

Thank you so much! What to do when you accidentally use hand washing detergent saved me! I would never have ever thought of salt. Thank you so so so much.

[edit] Test mode

My dishwasher has a hidden test mode; it's a Kenmore Ultra Wash. It is accessible by pressing WATER HEAT, NO HEAT DRY, WATER HEAT, and NO HEAT DRY in that order. FLaRN (talk) 21:44, 26 August 2006 (UTC)

[edit] Guano?

A change was made to suggest that Guano had been used as a detergent. I could find no evidence to support the claim and reverted all changes by that user, but I may have thrown the baby out with the bathwater... Please update the page as needed.

[edit] Original Research?

I removed this section (quoted below), as I think it breaks the Wikipedia:No original research policy. I believe the usual comment is to request the author to get the work published elsewhere, then reference it. It's nice that somebody took the trouble to test, but unfortunately, I don't think it belongs. Obviously, if people disagree, the edit can easily be reverted.

[edit] Loosely scientific study into machine vs hand washing

In order to see how accurate this is, a semi-scientific test was performed with an approximately five-place setting, using a medium sized washing bowl holding 12.75 pints or 6 litres (big enough for a round dinner plate). I believe that I am an efficient hand-washer, and I start with the bowl less than one third full and wash smaller items, rinsing them under the hot tap such that the hot water goes into the bowl. By the time I have finished the bowl is full. At this point the water would have to be discarded as too dirty to continue. I waste about 2 litres waiting for the hot water to come through from the tank. This is 8L/5P or 1.6 litres per place setting. The study quoted above suggests that hand washing 12 place settings would use 60L of water, or 5 litres per place setting. My guess is that the study required the person to leave the rinsing tap running continously flowing into the drain.

Specifications of various dishwashers at www.johnlewis.com (URL deliberately not href'd to avoid advertising) suggest UK specification washers take 14 to 16 litres, so assuming a full load of 12 place settings, this is approx 15L/12P or 1.25 litres per place setting.

I thus conclude that an efficient dishwasher thus is comparable to reasonably efficient hand-washing in water usage.

If hand-washing also allows the dishes to air-dry, then the energy usage is going to be very different; consideration also has to be given to how the water for hand-washing is heated - an efficient gas boiler in a cold climate (where waste heat also usefully heats the building) will be better than an electric heater (or the electric heater in the dish washer). Looking at the wider picture, there are also energy and pollution costs in manufacturing the dish-washer and the disposal or recycling of the unit when it reaches end of serviceable life.

[edit] Incorrect title

Should be dishwashing machine as a dishwasher is also a job/profession and is listed on the U.S. census as such:[2] Quadzilla99 19:35, 7 February 2007 (UTC)

[edit] Other types

I think sections should be added for the "drawer dishwasher" and the "in-sink dishwasher", both of which are variations of the standard dishwasher. HeirloomGardener 21:32, 21 May 2007 (UTC)

[edit] Dishwasher salt?

Where do dishwashers typically have a built-in water softener? Here in the US, I've never seen this. (We typically have a whole-house softener in areas with hard water.) The article seems to be written as if the built-in softener is standard. As this is not true in all parts of the world, I think some text should be added that indicates where this is typically used.

[edit] Sandblasting??

The sandblasting comment seems dubious (the powder dissolves completely in any detergent of reasonable quality). Unless a source can be cited it should probably be taken out:

Intuition suggests that a powder will provide a better scrubbing action due to a soft media sandblasting effect, though liquid detergents have marketed themselves as premium products. Inexpensive powders sometimes actually contain sand, which can be verified by dissolving the powder in boiling water and then passing the solution through a coffee filter; these detergents should be avoided to prevent wear of the dishes and the dishwasher.
