The SPS4HMW53G is a freestanding slimline dishwasher from Bosch – a brand well-known for its large appliances. On paper, it’s pretty impressive with its wide range of features and smart connectivity. But slimlines are often less efficient with energy and water, and they can be a nightmare to load up quickly. Can this Bosch buck the trend and prove not only to be a brilliant washer but also frugal and a breeze to use? Read our review to find out.

How we test dishwashers

5 Mar 2024

Cleaning

How we test cleaning

To test how well each dishwasher cleans, we dirty a range of dishes, glasses, cups and cutlery. Our menu of challenging grub and grime includes milk, tea, minced meat, eggs, oat flakes, spinach and margarine.

Quietness

How we test quietness

We assess how noisy the filling and washing stages of each dishwasher are, listening out for any loud or particularly irritating noises or tones. A five-star quietness rating will be almost silent, while a one-star will be very noticeable.

Drying plates & cutlery

How we test drying plates & cutlery

We inspect each item in the load after the wash has finished and score each and every item for cleanliness and dryness.

Drying plastic

How we test drying plastic

We throw in a plastic tub as it is an extra challenge to get completely dry. These are harder to dry as they don't retain heat like crockery or glass does.

Not leaving watermarks

How we test not leaving watermarks

The very best dishwashers will also prevent watermarks from developing on your cutlery, plates and glasses by whisking away any droplets before they can turn into watermarks. We check for this on every item.

Energy efficiency of main program

How we test energy efficiency of main program

We don't rely on the energy label to tell us how efficient a dishwasher will be. We run our own energy tests, measuring how many kWh the dishwasher uses for each program we test.

Energy efficiency of eco program

How we test energy efficiency of eco program

We measure how many kWh the eco program uses on an empty load and compare this others to see how efficient the dishwasher is.

Water efficiency of main program

How we test water efficiency of main program

We measure the flow of water in and out of the dishwasher to calculate the amount of water used in the main program.

Water efficiency of eco program

How we test water efficiency of eco program

We measure the flow of water in and out of the dishwasher to calculate the amount of water used in the eco program.

Ease of use

How we test ease of use

Ease of use is based on an expert panel assessment of how easy it is to load the dishwasher, adjust the height of the upper rack, and use the controls and door panel.
