Can You Run a Portable Dishwasher Overnight?

Faced with the lack of space in the kitchen, it is quite impossible to have large appliances! This is where portable dishwashers come in. These compact appliances can be placed near the sink to be stored in a cupboard when not in use. You can bring your portable dishwasher with you on vacation or at weekends. But how do you find the right dishwasher for your needs? How easy is it to set up and use a portable dishwasher? How much water does a dishwasher use? This article will answer your questions about portable dishwashers and how to use them.

What Are The Benefits Of Running A Portable Dishwasher Overnight?

Operating your portable dishwasher overnight will help you save electricity. Running your device during off-peak hours (cheaper) from 10:30 pm will reduce your electricity bill. This is only possible if you have subscribed to a Peak Hours/Off-Peak Hours offer with your energy supplier. This option allows you to take advantage of a price per kWh that is cheaper than the regulated electricity tariff during off-peak hours. Conversely, during Peak Hours, the price per kWh is higher than the regulated EDF tariff. The dishwasher’s delayed program can be used to program its start-up during off-peak hours.

Are There Any Drawbacks To Running A Portable Dishwasher Overnight?

Running your portable dishwasher at night is beneficial because it will reduce the cost of electricity consumption. Still, simultaneously, the device can turn out to be irritating due to the loud noise it produces during operation. This noise could disturb the entire neighborhood, keeping people awake and causing discomfort.

How Much Water Does A Portable Dishwasher Use?

A recent dishwasher consumes between 10 and 20 litres of water for each wash. The actual consumption of each model is indicated on the energy label at the bottom right. The water consumption of a dishwasher generally varies from 2500 liters per year to more than 4000 liters per year. Related to the cost, this represents a cost of 7 euros/year to 11.2 euros/year, a difference of 4.2 euros per year.

How Much Electricity Does A Portable Dishwasher Use?

Today, the energy classes of the majority of dishwashers start for the most energy-consuming at D and go up to A+++ for those who consume the least. When choosing your dishwasher, it is important to remember that the energy class will have a long-term impact on your energy expenditure.

To better understand, I have produced an example of achievable savings depending on the chosen energy class. For a class A+ dishwasher:

  1. Electricity consumption: 289Kwh/year x 0.15 euro/Kwh = 43.35 euro/year
  2. Water consumption: 3920 liters/year x 0.0028 euro/litre= 10.98 euro/year, that is a total of 54.33 euros.

For a class A+++ dishwasher:

  1. Electricity consumption: 237Kwh/year x 0.15 euro/Kwh = 35.55 euro/year
  2. Water consumption: 2520 liters/year x 0.0028 euro/litre= 7.06 euro/year, that is a total of 42.61 euros.

Hence, I can draw two conclusions:

  1. The cost difference in energy consumption between a class A+ and A+++ dishwasher is 11.72 euros, i.e 117 euros over ten years (the lifetime of your dishwasher).
  2. The difference in energy consumption cost between the class A+++ dishwasher and washing by hand is 7.06 x 5 = 35.3 euros/year or 353 euros over ten years!! (not counting your hours doing the dishes, of course)

How Do Portable Dishwashers Compare To Standard Dishwashers?

Unlike standard dishwashers, portable dishwashers are designed to be self-contained units that can be placed anywhere you can access water and drainage.

A standard dishwasher fits under your counter; flush with your kitchen cabinets. A portable dishwasher is finished on all sides and top so that you can place it anywhere in your kitchen.

Portable dishwashers are a great choice because they can easily fit into any kitchen design. The biggest difference between a portable dishwasher and a standard dishwasher is the number of dishes they can wash. A standard dishwasher can only wash a few place settings at a time. Forget washing pots and pans. Portable dishwashers can use as little as 3 gallons per load (about 11 liters).


What Are The Pros And Cons Of Owning A Portable Dishwasher?


  1. Easier installation since the device can be placed where desired.
  2. Easier connection access for maintenance and troubleshooting, especially if the dishwasher is not under the counter.
  3. A price is often more advantageous than a similar integrative model because there are no front door costs.
  4. A device that is easier to move when changing accommodation.


  1. A sound level higher than that of a similar standard model.
  2. More visibility than with a built-in model, which can harm the aesthetics of the kitchen.
  3. Easier clogging of the outer walls since they are in the open air

How Easy Is It To Set Up And Use A Portable Dishwasher?

Once the dishwasher is plugged in and installed, the first step is to adjust the water softener designed to remove minerals and salts from the water that can cause operational problems. The softener setting will determine the amount of salt used in each wash cycle. It must therefore be done after being well informed about the hardness of your water.

The next step requires filling the salt compartment with water and then regenerating salt. Finally, you must add the rinsing liquid, always referring to the instructions for use. Launching a first vacuum cycle before any use is recommended to identify any leaks at the connections is recommended.

Steps for Installing A Dishwasher:

1. Remove the packaging and check that the device is in good condition.

2. Read the device documentation and refer to it for each step.

3. Fix all the necessary elements if necessary.

4. Connect the drain hose avoiding any kinks.

5. Connect the water supply hose. Always be careful not to bend or crush the hose.

6. Plug the dishwasher into the wall outlet.

7. Check the stability of the device and adjust the adjustable feet if necessary.

8. Energize the unit and run a vacuum cycle to check for leaks.


What should you consider before buying a portable dishwasher?

Do not rush into the purchase of your dishwasher because this choice must be made according to very specific criteria that will be explained below:

  • The Size Of A Dishwasher

A portable dishwasher will, by definition, be compact, but the size can vary greatly from one model to another. In particular, ensure that your plates will fit and that you can store your dishes after each meal as you wish. It would be a shame to buy an appliance that is too small for your pans and plates. The capacity is generally indicated in the descriptive sheets, so remember to look carefully to avoid unpleasant surprises.

  • Automatic Programming

There are many dishwasher models today that allow you to choose automatic programming, which has two main interests:

  1. To be able to make a delayed start when launching your machine and thus take advantage of EDF’s off-peak hours if you have opted for this option.
  2. Being able to adapt water consumption and washing time to the degree of soiling of your machine.

Choosing a dishwasher with these two options can save you energy.

  • Drawer Or Cutlery Basket

You may never have seen this option, but dishwashers can now be fitted with a cutlery drawer instead of the traditional cutlery basket. This saves space at the bottom of the dishwasher so that you can easily put your big pans in there. Here too, we can think about saving space which means fewer wash cycles.

  • Noise: Silent Dishwashers

Great technological breakthrough: dishwasher manufacturers now offer silent dishwashers with greatly reduced noise. Dishwasher noise today ranges from 40dB to 53dB or more. Understand one thing in these figures: lowering the sound level by 3dB means dividing the noise by 2. So, lowering the sound level by 13dB means dividing the noise by almost 20!

Are Portable Dishwashers Worth The Investment?

A portable dishwasher saves a lot of time because you will no longer have to wash your plates, dishes, pans, and cutlery by hand. Moreover, contrary to what one might think, a dishwasher cycle consumes less water than washing dishes by hand; this is all the more true for a compact dishwasher which will require less water to turn. So you can save energy and money. A portable dishwasher is also easy to install and can fit into the smallest spaces. Therefore, it is perfect if your kitchen is very small and will not clutter the room.


Do you dream of no longer washing your dishes by hand and buying a dishwasher, but your kitchen is small? Rest assured, you can opt for the portable dishwasher to take over. The latter takes up less space than a standard model and is suitable for small rooms without cluttering them.

A portable dishwasher will be as efficient as a large one and will allow you to get perfectly clean dishes without getting tired and wasting time after your meals. Nowadays, there are many models on the market, both directly in stores and on book sales sites or online merchants. The offer is therefore very wide.

There are varieties of Portable dishwashers such as Bob, Klarstein, Bosch, Listo, etc. You will have a wide choice to find the model adapted to your needs and the layout of your room. To help you find your way around all these references, this article has provided answers to most of the questions you could ever ask when using a portable dishwasher.
