In terms of design, the COMFEE’ Countertop Dishwasher is sleek and modern, with a white finish that looked great in my kitchen. It is also very compact, so it won’t take up too much counter space.

The dishwasher is also very easy to clean, as the interior is made from stainless steel and the filters are removable for easy washing.

There are, of course, some downsides to such a great product.

It doesn’t get rid of “caked-on” food or mold as well as other products. And its build quality doesn’t really inspire much confidence.

The only thing I don’t like about it is that I think there should be a bigger warning sign on it telling people that it won’t work unless they put 5 liters of water in the tank.

I also noticed that the high temperature and air drying feature gave me sparkling dishes that came out so clean and dry that I could almost eat off of them again.

Don’t even get me started on the faucet adapter that came with it. It’s like they knew I wasn’t very handy.

So, if you want to feel like you have a tiny robot butler in your kitchen, get a Portable Countertop Dishwasher and live the dream.

How does dishwasher heat water

While traditional dishwashers rely on hot water from your home’s water heater to wash your dishes, these types of dishwasher models do it themselves.

Dishwashers that heat their own water have a heating element inside them that warms up the water to the right temperature needed to give your dishes a sparkling wash. 

So, you can rest easy in the knowledge that your dishwasher is a self-sufficient machine that doesn’t need any help from your home’s water heater.

Just don’t fret when you hear a strange noise coming from the back of the dishwasher. It’s just your dishwasher heating its own water!

Do dishwashers use hot water or heat their own?

The answer to this question depends on the model of dishwasher in use. Per Maytag, most modern dishwashers heat water with their own heating element.

Some dishwashers rely on hot water from your home’s water heater, while others heat their own water. It’s like a game of hot potato, but with water.

So, which is better? It all “boils” down to efficiency.

Dishwashers that heat their own water are more energy-efficient because they only use the amount of water they need and heat it to the right temperature. This is in contrast to traditional dishwashers that rely on a whole tank of hot water from your home’s water heater.

What to keep in mind when buying dishwashers that heat their own water

Here are a few factors to keep in mind when shopping for a dishwasher that heats its own water.

1. Size and capacity

Whether you are a family of five, or you live alone, or you host big dinner parties, or you simply stick to takeaways… The answers to these questions are what will determine how big (in terms of size and capacity) your dishwasher needs to be.

2. Energy and water efficient

You don’t want a dishwasher that’s a total energy hog because this means an increased utility bill.

You want something that’s energy-efficient, uses just the right amount of water it needs, and heats it to the right temperature.

Although this type of dishwasher might seem expensive upfront, they are sure to pay for themselves many times over by the cost savings you’ll get from using them.

3. Noise level

The noise level is important because no one wants to live with a noisy dishwasher.

So, it’s best if you choose a dishwasher with a low decibel ‘dB’ rating. These models are sure to run silently when in operation.

4. Price

Whether you’re on a tight budget, or you’re ready to splurge on a top-of-the-line dishwasher that can “almost give you a hand massage”, you want to find something that ticks all your ‘boxes’ and is within your budget.

5. Brand reputation and customer reviews

As with any other product, when shopping for a dishwasher that heats its own water you need to consider the brand reputation and reviews.

This is because the real life experience of other users can help you “mock up” an informed opinion of how “good” a dishwasher really is before you buy it.

After all, you don’t want to end up with a total nightmare of a dishwasher.

Can you use a dishwasher with no hot water?

Although you can use a dishwasher with no hot water, your appliance will have to work a lot harder to clean your dishes. And it’s more than likely you may not get the sparkling results you’re used to.

It’s like trying to win a game of Jenga with half the blocks missing. Sure, you can do it, but it’s not ideal.

Traditional dishwashers without hot water will give you all of that extra stress, but only reward you with less-than-stellar cleaning results.

Nonetheless, the choice is yours.

But as someone who’s tried to wash a casserole dish with cold water, I highly recommend going for dishwashers that heat their own hot water.

How much hot water does a dishwasher need?

The answer to this question usually depends on the load you intend to run in your dishwasher and how dirty your dishes are.

In other words, a small load requires a little amount of hot water, while a huge load requires a huge amount of hot water.

In general, dishwashers need water that’s between 120-140 ° F to give your dishes a thorough clean.

So, if your home’s water heater is set to a lower temperature, your dishwasher may not be getting the hot water it needs.

However, if your home’s water heater isn’t up to snuff, you can always opt for dishwashers that heat their own water.

It’s like having a personal water heater for your dishes. All of the fun, with none of the stress.

Just remember, giving your dishwasher the hot water it deserves means it will reward you with clean and sparkling dishes every time.


Can all dishwashers be connected to hot water?

No, not all dishwashers can be connected to hot water. This is because not all dishwashers have this feature. Nonetheless, checking the installation manual of your dishwasher will give you the proper info you need.

Do dishwashers have hot and cold inlets?

Yes, although this depends on the dishwasher in question. Some dishwashers are designed to heat up cold water, while some are designed to be connected to a hot water supply. As previously mentioned, the best way to know this is by reading through the owner’s manual of your dishwasher.

Do dishwashers use a lot of electricity?

Yes, dishwashers do use a lot of electricity. The amount of electricity consumed will depend on usage and size. However, it’s not entirely uncommon for dishwashers to average over 1,000 watts of energy per hour.


There you have it. Here’s a review of the best dishwashers that heat their own water. There are pros and cons to each dishwasher, so it’s quite difficult to choose the overall best best dishwasher with built in water heater.

You must also remember that when it comes to finding the perfect dishwasher that heats its own water, there are certain factors such as size, efficiency, noise level, price, and brand reputation you need to keep in mind. 

And of course, that little something about the features you desire in dishwashers.
