Everything You Need to Know About Dishwashers | Buying Guide

A common problem in today’s homes is a lack of space. If your kitchen is small, a compact, narrow dishwasher is likely to be more suitable for you, but if you’re spacious, a separate dishwasher may be better. Whatever your choice, in this section, we will answer potential buyers’ most frequently asked questions.


What is a dishwasher, and what advantages does it offer?


Invented in 1883 by Josephine Cochrane, a dishwasher or dishwasher is an appliance used to clean crockery and cutlery automatically. The dishwasher works by spraying hot water with detergent on the crockery, usually between 45 and 65 degrees Celsius. The washing cycle ends with rinsing. Believe it or not, resorting to a dishwasher has many advantages, as you’ll see in the following list: Save water. According to a Canal de Isabel II and BSH Electrodomésticos Spain study, you can save 30 litres more daily than if you wash by hand.

  • Now energy. According to a study conducted by the University of Bonn in Germany, they spend up to 10 per cent less energy than washing dishes by hand.
  • Save time. That, as we said in the introduction, you can dedicate to other activities. You can even leave it scheduled to do the homework at night if you have a quiet appliance.
  • Take care of your crockery. It’s quite a myth to think that the dishwasher spoils your glassware when it’s quite the opposite. However, you must incorporate products such as brightener and opt for dishwashers with additional functions to care for your dishes.
  • More hygiene. Your crockery will always be more hygienic if you wash with a dishwasher than if you do it by hand. Bayettes accumulate countless germs, while dishwashers incorporate powerful detergents that will remove harmful bacteria and microorganisms.
  • Watch your hands. You won’t have to deal with the usual detergents to wash in the sink that deteriorates your hands’ skin. Subjecting your hands too high temperatures and detergents are not recommended for your skin.
  • It’s more comfortable. You don’t have to scrub immediately after meals, and you won’t have the kitchen full of pots, glasses and pans all over the countertops, from dishwasher to the closet, directly.


What are the components of a dishwasher?

In case you don’t know them, the dishwashers have differentiated elements to do their job. In this question, we summarize the key parts or areas of the dishwashers and their function within the washing cycle of this small appliance. Below, and to make it easier to view, we explain them in a list:


What types of dishwashers exist on the market?

  • To make a good purchase, you have to be clear about what type of dishwasher you need for your kitchen and how much space you have, although the latter aspect we will see in-depth later. Basically, two types of dishwashers make obvious differences, as you’ll see below in the following table: Free to install: Also known as “standard”, they can be located in any house area, although they have to be near a water intake. It can reach up to 14 cutlery or services and is usually white or stainless steel.
  • Integrated: Also called “panel cables”, they are integrated with the remaining furniture of the kitchen and are sometimes installed in empty spaces, such as under a piece of furniture, going completely unnoticed. They are usually more expensive than the first option.


Are there differences in the capacity of the dishwasher?

Yes, because it’s not the same as living with two friends or you’re part of a large family. We can establish the differences in capabilities of these appliances by guiding us through the services or cutlery. Service is the cutlery used by a person in a meal, including coffee. Let’s look at the different capabilities in the following table:


What exactly is a compact dishwasher?

They are a small dishwasher and free installation. Generally, up to 6 cutlery is available and is well suited for small dwellings. They have usually installed in laundry rooms or on the kitchen countertops, and their consumption is lower, so we will contribute to improving the environment and saving on electricity billing.

According to a study conducted by the Institute for Energy Diversification and Savings (IDAE), the dishwasher is the fourth most energy-consuming appliance in a home, behind only the refrigerator, washing machine and television.


How do I install a dishwasher?

It’s effortless, but you have to have a certain skill. In these lines, we summarize how to do it without major complications. The first thing is to join the sink water intakes with the appliance through pipes that incorporate passkeys. They are also called “record”. Second, connect the dishwasher to the electric current.


What maintenance does a dishwasher require?

  1. If we want our small appliance to last us as long as possible, it is necessary to follow periodic maintenance guidelines and make proper use of the appliance. Here are some helpful tips for keeping our dishwasher in a healthy state: Check salt, polishing and detergent levels. Before running the dishwasher, it is advisable to check the levels of these products. You should not forget any of them, especially if you live in an area with hard water.
  2. Place the dirtiest crockery in the lower area. Thus, you will get the jet of water directly and with all its power. This advice is recommended if you do not have clear specifications from the manufacturer regarding the dishes’ placement.
  3. Obstacle-free swivel arms. Make sure nothing makes it difficult to turn the blades or swivel arms inside the dishwasher.
  4. Place plastic utensils and cutlery on top. In this way, they will be far from any resistance that can deform them.
  5. The proper dose of detergent. This is an important aspect, so follow the manufacturer’s recommendations. A very high dose does not generate more cleaning, but you waste the detergent, while a shallow one will not provide efficient washing.
  6. Cutlery down except knives. Follow this advice and do not swear stainless steel with silver; they should be indifferent baskets. Silver must also be removed from the dishwasher before drying.
  7. Do not load the dishwasher above its capacity. Doing so can usually deteriorate your rotating arms.
  8. Clean up the food scraps. And do it before you start the washing process. This will prevent the gears inside and pipes from jammed.
  9. Check the filter. It’s a procedure you should do two to three times a month if you use the dishwasher frequently. Remove it counterclockwise, and remove possible debris. Then wash it with plenty of water.
  10. Periodic cleaning. Finally, use a specific product to perform deep cleaning when needed.


How does a dishwasher work?

  1. Surely you could explain very quickly how a dishwasher works: just put the dirty crockery, close, hit a button and wait for the washing cycle to end. So far, a simple explanation, but the dishwashers follow a series of guidelines that better understand how they work, as you will see in the following list: Water uptake. The first thing the dishwasher does is fill a small tank in the inferno part with water.
  2. Warm-up. Except in prewash, the dishwasher uses hot water. This operation is performed on the electric heater, located in the tank located under the rotating arms.
  3. Detergent. After heating the water, the dishwasher adds the detergent, which will vary depending on the previous programming.
  4. Washing. Water is expelled through the rotating arms or sprinklers. Thanks to pump pressure, the arms rotate and expel the water tightly so that the crockery and glassware are gleaming.
  5. Drainage. Once the crockery is washed, the appliance empties the dirty water through the drain enabled for it.
  6. Cleared up. The dishwasher now repeats the whole process but does not include any detergent. The water is usually cold, but some appliances also use hot water in this section.
  7. Empty. The appliance expels excess water.
  8. Brightener. If you’re looking for your glassware to come out dry and unmarked, add a brightener to the corresponding compartment.


Buying Guide For Dishwasher

Buying Guide For Dishwasher

Purchasing a dishwasher is an investment, so consider several criteria so as not to miss your purchase. Whether capacity or measures, they are all important elements that need to be contemplated to choose the most suitable appliance for our needs. To make your task easier, we show you the most important aspects below.


A dishwasher’s capacity is usually measured by services or cutlery, so you must make a five-year projection on the number of diners. If you are usually many at home, opt for an appliance for 12 or 14 cutlery. Remember that service consists of all the utensils that a person resorts to during a meal.



Another option to buy a dishwasher is its measurements, which will not be the same in a laundry room as in a kitchen. Depending on the space available for installation, there are different appliances suitable for your needs. In the table below, you can see different options depending on the size of the device.


Noise level

An important aspect to behold is the sound power of the dishwasher. If you use it often, you’ll hate it being very noisy. Most devices have power between 45 and 60 decibels (dB), a figure that you will find on the energy label. The lower it is, the less you’ll notice the noise when the appliance is at full capacity.

If you want to use it at night, choose a model that doesn’t exceed 45 decibels. If you’re going to place it in a basement, for example, make sure it doesn’t exceed 55 dB. It won’t bother you, and the appliance will function equally in a partially silent way. He thinks the less noise, the more expensive it.


Washing programs

Dishwashers usually include different washing programs, and each is specific to perform a type of function. It is not the same as an echo program as an intensive program to give an example. Next, we explain in a list the differences guided by the washing temperature that this appliance reaches.

  • Eco Wash: With it, you save up to 16% more water and up to 20% light, according to a statistic from the OCU (Organization of Consumers and Users). The temperature reaches 50oC or less and takes an hour longer than the normal program in the washing cycle.
  • Pre-washed or rinsed: Both prewashing and rinsing corresponds to the same program, indicated to rinse the dishes with cold water.
  • Express washing: Wash and dry in half the time, usually at a temperature of 65oC. It is indicated for crockery that has already been rinsed before.
  • Intensive washing: It is suitable for dirtier crockery, including pans or pans with embedded dirt. Generally, it uses a maximum of 70 oC, and its duration usually lasts up to 2 hours.
  • Normal washing: The temperature usually reaches 55oC and is the most used daily. The duration of the program is approximately one hour.
  • Half-load washing: Some dishwashers include half-load washing, indicated when we need crockery, but the dishwasher container is half empty. In these cases, this program is used to save electricity, water, and detergent by up to 20%.


Energy efficiency

Energy efficiency is reflected in different labels ranging from letter A to G, the latter being the most consuming. In general, you will find a dishwasher with energy certification A, although this can be A, A+, A++ and A +++, corresponding the last to the one that consumes the least in terms of energy. Louis-Ferdinand CélineFrench writer “Death is just a cleaning machine.”


Additional features

Today’s dishwashers incorporate several features that can be of great interest. Some include the AquaStopfire protection system, other project program status to the ground, and others include specific baskets for silver cutlery or bottle hooks. Whatever your need, I’m sure there’s a dishwasher for you.

On the other hand, make sure that the appliance chosen includes the eco-program and that it has a cold water program to save more energy. And, of course, don’t forget to choose an energy-efficient dishwasher because you won’t regret it and you’ll be delighted with your new appliance.



Buying a dishwasher or dishwasher includes considering several key factors not to err on purchase. One of these essential criteria refers to its sound power. If we do not have just time and want to leave the appliance ready to wash the crockery at night, it is advisable to opt for a silent model, no more than 45 decibels.

Also, and as you have seen, there are fundamental criteria when making your acquisition. The type of dishwasher, its measures or the variety of washing programs are also issues that will affect your budget and, of course, your comfort, just as a well-known brand will always give you more confidence and it will be easier to find spare parts.
