Before you buy a dishwasher, you should think about how much time it saves you. A dishwasher makes life easier in the morning, especially if it is really dirty. You don’t have to spend time scrubbing or rinsing or washing dishes.

The most important thing is its size. A big enough dishwasher will take up less space than a hand-held dish washer, but a portable dishwasher is more expensive; and it has to be smaller than what the family needs to use every day, so you don’t want one that sits unused in the corner of the kitchen because it’s too big.

Another good reason for buying a dishwasher is that with one of these you can get your dishes off the counter and put them into the drawers where they belong without worrying that they’ll be damaged by water or grease from the sink, standing on end on the counter or being knocked over onto the floor by accident.

The second great thing about a dishwasher is that it is the easiest appliance to install yourself. It has no moving parts; all you need to do is plug it in, not even turning it on. The hardest part is probably pushing the dishwasher in through the front door.

The main reason you need a dishwasher is because of dishes. They don’t just leave a mess; they are also hard to clean up. There are two ways of doing this: You can have someone else do it for you, or you can do it yourself. If you hire someone, you get somebody to come and do your dishes for you, most likely at least once a week in the summer. Or if you pay someone to wash your dishes for you, it will be expensive, since there are so many of them: if your place gets used every day by four or five people every evening, and if each person uses one bowl, plate and glass per evening at most, then washing your dishes is going to cost something like ten times as much as having somebody else do them for you.

If you wash your own dishes, then things get harder still. You haven’t hired anybody but the dishwasher itself. But if you try to wash everything by hand in one go,

A dishwasher is a machine that cleans your dishes, and it can do so more efficiently than you can.

That’s rather obvious. But if you are in a kitchen with lots of dishwashers, you might wonder why you still have to wash dishes yourself. There are three reasons.

Firstly, cleaning up after dinner is a social activity: it’s not something people do alone. Everybody who helps at dinner gets involved in the clean-up. That’s why a dishwasher can’t substitute for having people around to help when needed. After all, people can’t always help – they aren’t always available, they are busy doing other things, and so on.

A second reason is that washing dishes is physically demanding work: it takes physical strength, endurance, and skill. Even when you do it by hand, there’s some bending and stooping involved. With a dishwasher you just put the dishes in the machine and it does all the work for you (this is true even with the “dishwasher-safe” glasses and cups).

If you have a dishwasher, it is because you want more time to do more of the things you’re actually excited about. So get a dishwasher. And maybe a washing machine too. Then put your house on the market (to help pay for it), and use that cash to buy something else that makes you happier.

So if you’re thinking of buying a dishwasher, don’t just think about which one is cheapest. Instead, ask yourself: “What kind of life would I want to lead if I had this?”

There are three basic reasons you might want to buy a dishwasher:

1. You don’t know how to wash dishes.

2. You have dirty dishes, and you’d like to wash them without getting your hands dirty.

3. You’re lazy, and you’d like the dishwasher to clean for you.

But what about the fourth reason? For example, maybe you’re a professor of English and your wife is a professor of mathematics who doesn’t understand the importance of washing dishes. Or maybe you’re a professional athlete and your wife thinks it’s poor form to wash dishes before going to bed; she says it shows disrespect for the team chef who has worked all day preparing a banquet for you. Or maybe you’re on a diet, and this is the easiest way to convince yourself that eating out is reasonable.

The last reason is probably the most common one: people who think they would rather not wash dishes are often wrong.

Dishes are heavy, dirty, and annoying. But there is no way to get around them.

A dishwasher is a mechanical device that takes dirty dishes and heats them up very quickly in a hot water vapor solution. Then it shoots the warm water back at the dishes, where it evaporates most of the water. The result is a dry plate.

In theory you could run your dishwasher with cold water and keep your dishes perfectly dry. That wouldn’t be very efficient, though: the energy needed to heat the water would be wasted.

Nowadays we have space heaters that work the same way. You put a bottle of hot tap water in them, and about an hour later you come back to find that your home has been heated without using any electricity or fossil fuels at all.

You could use a dishwasher like this for washing clothes, but it would probably cost too much for home use.

The most expensive part of your dishwasher is the water, so it also makes sense to use the cheapest water that you can find.

To choose a dishwasher, there are two simple questions to ask: 1) Is the water inside chlorine? If it says “yes,” then it probably contains fluorides, which are bad for your teeth. Chlorine kills bacteria, but it won’t work without salt and minerals. If the chlorine is not in your tap water, you can buy chlorine to put in your tap water. The best source of chlorine is a swimming pool; tap water won’t do because of all the minerals.

If the dishwasher’s owner didn’t notice or didn’t care about this problem, he probably doesn’t care about you either.
