Dishwasher Buying Guide

Dishwasher Buying Guide

Dishwashers are useful appliances to have in any home. They save you the time and effort of scrubbing dishes by hand – and energy-efficient models can even save you money on your bills compared to hand washing. Our dishwasher buying guide gives you all the ‘need-to-knows’ before making your purchase.

We’ll take you through all of the important considerations, including:

What is a dishwasher and how does one work?

Dishwashers are electronic appliances that use hot water and cleaning detergent to clean, rinse and dry dirty dishware, cookware and cutlery. Unlike traditional hand washing, which relies heavily on physically removing dirt, an electronic dishwasher is designed to save the owner on time, effort and even money.

When buying a new dishwasher, you’ll need to think about things like its size, how you’d like it to fit in your kitchen and any additional functionalities you’d find helpful.

Choosing your fit

First things first, you need to determine the type of dishwasher fit you’d like for your home. There are three different types to choose from: freestanding, semi-integrated and fully integrated. The main things to consider when choosing are whether you’d like the dishwasher to be on show and which fit would be most convenient for you.

Freestanding dishwashers


Freestanding dishwashers stand independently and a fascia panel is not needed. The exterior and control panel are exposed with a freestanding dishwasher. They can be placed underneath a worktop or anywhere where there's a water connection and a drainage point.

Integrated dishwashers


Integrated dishwashers are fully built into the kitchen units. If you opt for an integrated dishwasher, it’ll be hidden behind a cupboard door to give a more unified look. The control panel sits on the top lip of the door, which gives you easy access when choosing your dishwasher program.

Semi-integrated dishwashers


Semi-integrated dishwashers are partially hidden. As with a freestanding model, the dishwasher panel will always be on show, but the rest of the appliance will be concealed by a door matching your kitchen cabinets. This fit offers the best of both worlds.

Dishwasher sizes

The next step is choosing your dishwasher size. Keep in mind that your dishwasher should complement your needs and kitchen space.

Dishwasher place settings

Dishwasher capacity is measured in ‘place settings’ – this refers to how many sets of dishes, cutlery and glasses an appliance can clean in one go. If you had eight people for dinner, you’d need a dishwasher with a place setting of eight to get everything sparkling clean with one cycle (aside from pots and pans).

One place setting should allow room for:

  • One large dinner plate
  • One small plate
  • One cup
  • One saucer
  • One bowl
  • One drinking glass
  • Cutlery: a knife, fork, dessert spoon, and teaspoon
Place setting No. of people No. of items (excl. pots & pans)

If you have a larger family or love cooking for lots of people on a regular basis, then you’ll need a larger place setting. People with smaller families who don’t tend to cook for large groups will be fine with a smaller place setting.

Full-size dishwashers

Full-size dishwashers

Full-width dishwashers are usually about 85cm tall, 55-60cm deep and 60cm wide. They will fit 12+ place settings (120-150 items) and are ideal for larger households.

Slimline dishwashers

Slimline dishwashers

Slimline dishwashers are around 45cm wide. Similar to full-size dishwashers, 55cm tall and 55-60cm deep. They will fit roughly 9-10 place settings (90-100 items) and typically have a ‘small on the outside but large on the inside’ design.

Compact dishwashers

Compact and table-top dishwasher

Compact dishwashers are handy for anyone who has limited space in their kitchen area. They can sit on top of a counter as they’re much shorter in height at around 44-45cm, with a capacity of around 6 place settings (40 -60 items). Keep in mind that they’re not necessarily cheaper than a full size dishwasher.

How to measure for a new dishwasher

It doesn’t matter what type of dishwasher you’ve chosen for your home. The most important thing is to measure the dimensions and make sure it will fit seamlessly into your chosen area. Below we explain how to do this. Measuring for a dishwasher

  1. Choose the right model from integrated, semi-integrated to freestanding dishwashers.
  2. Integrated dishwashers only need the width to be measured (60-70cm) because the height (82cm) and depth (55cm) are the standard sizes. Freestanding dishwashers have a general height of 84cm to 85cm, 60cm width and 59cm to 60cm depth. If you’ve chosen an integrated or freestanding slimline dishwasher, they have a standard width (45cm) and the same height and depth as the relevant standard model.
  3. Another simple way to measure for your new dishwasher is to measure the dimensions of your current appliance if you are choosing to upgrade. Make note of these for reference.
  4. You can also measure the chosen area for your dishwasher to be on the safe side. This will guarantee a nice snug fit for your appliance when making your choice of size.
  5. You can find the dimensions of our products within the product description or feel free to contact us for assistance if you need.
  6. Once you know the dimensions and are ready to purchase your appliance, select our installation service at the checkout to make the process even easier for you.

Dishwasher energy ratings

There are two main reasons why you should care about efficient energy levels: your household budget and the environment. The energy ratings go from A+++ to D, with A+++ being the most efficient. Larger dishwashers with A+++ ratings tend to be the most efficient. You can achieve the lowest energy and water consumption by making sure the dishwasher is full for each wash cycle.

Delay start

Dishwasher FAQs

You might have lots of questions when choosing a dishwasher. Below are some dishwasher FAQs that customers tend to ask us. Can’t find an answer to your question here? Get in touch with our team today and we’ll be happy to help.

How much water does a dishwasher use?

Dishwashers don’t use much water when compared to handwashing. A dishwasher will use around 11 litres of water per wash cycle. Whereas, hand washing will generally use about 60l. You can save up to 18,000l of water per year with a dishwasher!

How much electricity do dishwashers use?

Dishwashers use roughly 1200 to 2400 watts depending on the type, although, on average, a dishwasher will use 1800 watts. This is the same amount of energy used to power a hairdryer for 10 minutes.

How much does a dishwasher cost to run?

On average, a dishwasher will cost between £40 and £60 per year to run. More energy-efficient models will cost the least.

How long does a dishwasher last?

A dishwasher should last around 10 years.

Where can I install my new dishwasher?

Whichever fit you choose, your new dishwasher will need to be installed near a water supply and drainage point.

What does dishwasher salt do?

Dishwasher salt softens the water to gain better cleaning results. Hard water makes it difficult for dishwasher detergents to dissolve because it has more lime. Hard water affects the cleaning results.

How should I clean my new dishwasher?

The foundation of a lot of odour issues with dishwashers is due to food remnants sitting in the appliance. After each cycle, make it a habit to remove bits of food. Rinse the dishwasher filter by running it under hot water safely. Use an old toothbrush to scrub the filter as you do this. To clean the interior of your dishwasher use vinegar. Fill the safe bowl with 1 cup of vinegar and put it on a hot water cycle. The vinegar will remove any grease, food, residue and grime.
