One can say that dishwasher has to be one of the best scientific technologies ever. Who would’ve thought back in the ’80s that you could wash dishes without spinning the wheel? Well, if you don’t know what it means, here’s a little background.

Back in 1850, Joel Houghton invented the first dishwasher with the hand-turned wheel attached that would throw water, and the scrubbers will, you thought right, scrub it. It was a great machine, but it used a lot of water and sometimes even broke dishes.

In 1886, Josephine Cochrane improved the dishwasher by inventing the first rack to stack dishes which would use less water and be gentler on the dishes. Her dishwasher was such a success that at the 1893 world fair, she was awarded a medal for her design.

Cochrane’s dishwasher improved even more by using electricity in 1903 and becoming the first portable dishwasher in 1967.

Back then, there wasn’t any concept for hot or cold-water dishwasher concept. Anybody who would wash dishes knew it would be rotating the wheel, letting the machine (however you call it) run some spins and there you have almost-well washed dishes.

As far as I knew, as someone who is keen at washing my utensils especially, I think hot water does the work. It takes off the hard stains more rapidly than cold water.

But if I am in a hurry and need to get things done quickly, I rub off the hard stains by hand under tap and put the half-washed dishes in the dishwasher. Though it takes more time and effort, I know for one that the dishes will come off shinning.

So now that you know all that, you’re probably wondering if you can run a dishwasher without hot water. And the answer is… yes!

You can run a dishwasher without hot water, but it will take longer to wash the dishes, and they may not come out as clean. So, if you’re in a hurry or have particularly dirty dishes, you should use hot water. Otherwise, cold water will do the trick.

However, one thing to keep in mind is that if you use cold water, your dishwasher will use more energy to heat up the water. So, if you’re trying to be energy-efficient, you should use hot water.
