Do Countertop Dishwashers Heat the Water?

Traditional dishwashers have built-in access to both hot and cold water. However, countertop dishwashers do not. Instead, some are equipped to heat the water internally, while others rely on an outside hot water source such as your kitchen faucet.

Since hot water is required to sanitize dishes, it is important to understand how your particular dishwasher gets its hot water supply.

How Do Countertop Dishwashers Get Water?

Not all portable dishwashers are created the same, and there are a couple of methods in which they receive water. Most countertop dishwashers hook to the kitchen faucet, using that water supply to run through its cycles. Depending on your particular model, you may need to have access to hot water in addition to cold.

For individuals who need even more portability, some countertop dishwashers allow you to pour water directly into a reservoir, eliminating the need for a running water source. For this setup, the machine features an internal water heater and holds approximately one gallon of water.

How Much Water Does a Portable Dishwasher Use?

It's no secret that washing dishes uses a lot of water. However, according to Consumer Reports, dishwashers use less than half the water they did in the past.

Portable dishwashers use less water than both hand washing and conventional dishwashers. While handwashing wastes the most water at approximately 27 gallons per load, conventional dishwashers use roughly six gallons.

However, with a countertop model, you'll only use around two to three gallons of water. Even more, countertop dishwashers save space and use less energy. However, these portable units are typically not as strong as their permanent counterparts. Therefore, many are unable to remove tough stains, stuck-on food, and nasty grease residue.

Who Can Benefit from a Countertop Dishwasher?

Countertop dishwashers can be useful for several groups of people. If you live in a small apartment or townhouse, you may not have access to a full-size dishwasher. College students living in dorms can also greatly benefit from them.

Even if you have a large home with a built-in dishwasher, you can utilize a portable unit in your RV or take it on vacation for use in your hotel room.

Countertop Dishwasher VS. Portable Dishwasher

Although the two terms are used interchangeably, they are not the same. Countertop dishwashers, as the name implies, are small and fit on your kitchen counter.

Some feature built-in water reservoirs and water heaters, while others can only be used if you have an available water supply. Most countertop models only hold approximately two place settings; however, some can fit up to six.

Portable dishwashers are actually not as portable as countertop dishwashers. Portable washers are pretty large. Some are almost the size of built-in models.

However, unlike conventional dishwashers, portable units have wheels on the bottom and connect to your kitchen faucet. You can wash a wide array of dishes at a time, and most will even hold pots and pans.

What's the Point?

Once learning this, the question often arises of why you would need a large dishwasher that is not permanently attached to your plumbing. If you live in an apartment complex that does not have a dishwasher, you don't want to waste money installing one into a home that is not yours.

If you have enough room to store it, a portable dishwasher will save you time and effort, and you can take it with you when you move.

Countertop dishwashers are not designed to connect to your main water line. For this reason, it is not usually plausible for them to be installed under the sink. However, you can easily store the unit under there to get it out of the way until you're ready to use it again.

That being said, if the dishwasher is equipped with a pump and the hose is long enough to reach the faucet, it can be hooked up under the sink. However, it is not recommended that you connect it directly to your plumbing.

Does a portable dishwasher need a garbage disposal?

Portable dishwashers do not require garbage disposals. However, you will need to ensure you are not loading dishes into your machine with stuck-on chunks of food. Although, some portable dishwashers feature filtration systems that prevent food from clogging the hose.

When should I turn the water off on my portable dishwasher?

When your dishwasher has finished its cycle, you can turn the water off at any time. You do not have to turn it off immediately. Countertop dishwashers use a hose to pull water from your faucet.

The dirty water is then discharged into the sink from the outgoing hose. When the cycle is over, your dishwasher hose will block the water from pouring out of the kitchen faucet, so you don't have to rush to turn the water off.

Conclusion

Countertop dishwashers come in a variety of shapes and sizes with varying degrees of features. Many countertop models feature built-in water heaters, but this is not the case for all of them. Make sure to check the speculations before purchasing your new appliance.

    Some countertop dishwashers do dry dishes but not all the way. It uses residual heating. During the final rinse, the water is heated for a spotless shine. Instead of draining the water, it saves it to dry dishes. When the water is no longer needed, it drains. This type of heating uses no outside air or power.
