The WIW28301GB is the first fully integrated washing machine we’ve tested from Bosch since 2017. It can hold around 8kg of cottons, which makes it as roomy inside as many freestanding machines. Bosch also claims that it's very quiet. But we test each washing machine’s noise levels, as well as its clothes washing, energy and water use and even how easy it is to live with. Read our full review to find out whether this premium integrated washing machine is worth splashing out on.

The overall Which? test score is made up of the following star ratings, all determined by our rigorous lab tests.

How we test washing machines

2 May 2024

Overall cleaning

How we test overall cleaning

The combined cleaning star rating is based on the wash results from our tests for both the 40°C cottons and 40°C synthetics wash programmes.

Water use

How we test water use

We measure the amount of water used by the machines on both their cottons and synthetics programmes when washing at 40°C.

Cotton wash

How we test cotton wash

We check how good each washing machine is at removing stains when washing cottons at 40°C and when loaded to 80% of the machine’s capacity.

Synthetic wash

How we test synthetic wash

This star rating shows how well each washing machine removes stains when washing synthetic fibres at 40°C. For this synthetics test, we load each machines to its listed capacity for synthetics.

Rinsing efficiency

How we test rinsing efficiency

We check how well each machine rinses detergent away from clothes by stopping the machines just after the rinse phase and then analysing the remaining water for signs of detergent. We use a spinning machine to extract the water to analyse.

Spin dry

How we test spin dry

We weigh the clothes we wash before and after the wash to be able to judge how well each machine spins water away.

Ease of use

How we test ease of use

We run more than 50 ease of use assessments as part of our tests. We look at how clear the instructions are, how easy the machine is to load and to unload, we check the clarity of markings on the control panel and how easy the controls are to use. We also take a look at how easy it is to use the detergent drawer.

Program length

How we test program length

During our tests we record how long both of the wash programmes we test take to run. The star rating is based on the length of the programmes and is relative to the capacity of the washing machine.

Noise

How we test noise

We use an expert panel to listen to each machine as it fills, washes, spins and drains. Our panel listens for the normal operating noises as well as any annoying sounds the machine makes. A five star machine will be just about as quiet as a washing machine can be. A one star machine will make a lot of noise as it fills, washes and spins.

Energy efficiency

How we test energy efficiency

We record the amount of energy used by the machines on both their cottons and synthetics programmes when washing at 40°C.
