Things to Consider

If you have a good dishwasher, you won’t have to wash dishes by hand anymore. Our tests and studies showed that the way different dishwashers clean and dry your dishes can be very different, even if they look the same. A buying guide is given below that will answer all of your questions before you spend your money.

Reasons to choose an 18-inch dishwasher

There are two main types of dishwashers you can get if your kitchen is very small: 18-inch or portable. The thin design of 18-inch dishwashers means that they can fit in small spaces while still being able to clean a good number of dishes. If you only live with one or two people, these dishes are also a good choice because you don’t have to wait as long for them to fill up before you can use them. Last but not least, these machines use less water and electricity than bigger ones.

Features to consider when choosing an 18-inch dishwasher

When picking out an 18-inch dishwasher, there are a few things you should think about, just like when picking out any other device. The size, volume, sound level, and Energy Star rating are some of the most important things to look at. The most important things to look for in a dishwasher are summed up below.

Choose a wash cycle

In general, 18-inch dishwashers have the same settings as full-size ones, so you won’t have to give up anything to get a smaller model. You can change more things about the washing cycle if the dishwasher has more settings. For instance, if saving water is very important to you, you need a machine that can do that. You need a model with both heavy and delicate cycle settings, though, so you can be sure that all of your dishes will be fine inside, no matter how tough or fragile they are.

Setups for places

It’s important to know how much an 18-inch dishwasher can hold because these small types don’t have much room. Expect to be able to wash nine to ten place settings at once. This should be enough for small homes.

How many racks

From one dishwasher to the next, the number and types of racks will vary, so pick one that fits the way you plan to use the racks. You should choose a dishwasher with flexible racks, for instance, if you want one that can fit your stir-fry wok or your big pots. Some types have a drawer at the top where you can keep fragile things like knives and glasses.

Sizes in general

In line with their name, 18-inch dishwashers are 18 inches wide and often a little less deep than other types. Their doors open downwards, just like full-size dishwashers’ doors do. Many of them are made to fit in the space that a kitchen drawer takes up. Also, make sure you look at dishwashers that cost less than $400 that are small, stand-alone types that can be put on your table, for example.

Level of sound

Dishwashers can get pretty loud, so if you want one that won’t make it hard to talk, look for one that has a good reputation for being quiet. A lot of dishwasher brands say that their machines are very quiet, but it’s still a good idea to read customer reviews to find out what other people think about how loud the machine is. There are models that are very quiet (36 dB) and fairly quiet (55 dB). Some machines have overnight cycles, so you can set them to wash the dishes without waking anyone up.

Built-in or stand alone

Whether you pick a built-in or independent dishwasher relies on how your kitchen is set up and what you like.

Most of the time, built-in models have more features than freestanding ones. For example, built-in models often have more wash cycles, more spray arms, and focused sprays for cleaning dishes that are harder to clean, like baking plates or pots.

Built-in dishwashers are small enough to fit under your counter and give your kitchen a sleek look that many people like. Dishwashers that stand alone, on the other hand, can be put anywhere in the kitchen because they are finished on all sides. However, you can move your independent dishwasher with you when you do, but not a built-in one because it is forever attached to the wall. Finally, a detached dishwasher may give you more room for storage and cutting or preparing food because you can use the top of it for these tasks.

Feature for delay

The feature of delay With many dishwashers, you can set the machine to start at a later time, so for example, when you get home from work, the dishes will be clean. Some models, like the Frigidaire FFBD1821MS, have a delay of two to four hours. Other models, like the Bosch SPE68U55UC, have a delay of up to twenty-four hours.

Getting an Energy Star

On the energy Star list, dishwashers run from very efficient (A+++) to not very efficient (D). Some models have smart features that use the right amount of water for each type of run of washing. It’s best to get a dishwasher with the ultra-efficient energy star label, but it’s important to remember that any dishwasher is better than washing dishes by hand. To do this, run your laundry less often. This saves water, energy, and money.

Following the ADA

It means that the machine is safe for people with disabilities to use.

Most models on the market are ADA-compliant, but if you or someone in your family has a disability, you should make sure that the feature is available before choosing a model.

Promise of Warranty

Most dishwashers come with a limited warranty that covers parts and work for one year. If you want extra peace of mind, you can usually buy an extended guarantee that lasts up to five years.

How to keep your dishwasher clean and in good shape

If you want a properly washed load every time, you need to keep your dishwasher clean. Before you start to clean the dishwasher, make sure the power is turned off. The filters get clogged with food, so you should try to clean them every time you use the machine. The dirt that is stuck in the filter should be easy to remove with a simple rinse. One of the best ways to keep the dishwasher clean is to run it often.

Make sure you check on the spinning arms often and clean them by spraying water on them. If there is too much on them, they won’t shine like new. And at least once a month, clean and clear the drain. To de-scale your dishwasher, put a special powder for that purpose in the soap dispenser and run an empty cycle.


Can I put my dishwasher together by myself?

As long as you have the right tools and follow the directions in the dishwasher’s guidebook, you can put it in yourself. Putting in a normal dishwasher will take about an hour and a half to two hours, but that doesn’t include any extra water or electrical work that might need to be done.

Do I need to buy any extra power lines or hoses for installation?

Depending on the pipes and electricity in your kitchen, you might need extra things to put in your dishwasher. To connect a new water source, you may need self-cutting valves, but most types come with the hose pipe you need for installation.

Do you think it’s okay to use liquid dish soap in your dishwasher?

Do not put hand-dishwashing soap in a dishwasher. The foamy suds that this type of detergent makes will fill the machine and overflow. Always use dish soap that is made to work with dishwashers.

Can you dry food in a dishwasher?

Every cleaner dries the dishes, but some do it in different ways. Some of the most common are heated rinse, where the machine raises the temperature of the water near the end of the cycle and then pulls the water away from the dishes; heated air, which is common on older models; and fan, which moves air around to dry the dishes.

Would it be better to rinse the dishes first before putting them in the dishwasher?

You don’t need to rinse the dishes first before putting them in the dishwasher; the soap needs to work on dirty dishes. Also, using the sink to do the pre-rinse is a waste of water and energy. But you should scrape off any food that’s still on the plates before you wash them.

Our verdict

You can read reviews of ten of the best 18-inch dishwashers on the market in our guide. The Edgestar BIDW1802SS is only 18 inches wide, but it has sturdy racks that can fit up to 8 place settings. The top rack can even hold heavy things. For those who want something movable that can clean well and quickly connect to any kitchen tap, the SPT SD-9263SSB is a great choice. No matter what kind of dishwasher you want to get rid of the job of doing the dishes by hand, you should think about how many dishes you need to clean every day, how loud the gadget is, and how much energy it uses, among other things.
