A washer-dryer does the job of a washing machine and clothes dryer in a single appliance. Check out our buying guide and test results before you buy.
We test washer-dryers using a 3.5kg load because our research shows this is about in the middle of the range of amounts that most people wash, whatever the size of their machine.
We use a normal, cold wash. If there isn’t such a cycle, we use the closest approximation.
Our overall score comprises two equally weighted sub-scores:
- washing performance (70%)
- drying performance (30%)
Dirt removal (50%): Calculated according to a formula in the standard, which reduces the score in proportion to the variability of dirt removal over a range of test swatches in the wash load.
Water efficiency (10%): Based on the amount of water used in the whole cycle, per kg of clothes.
Rinse performance (20%): Based on the amount of detergent residues after rinsing.
Spin efficiency (10%): Calculated from the amount of water remaining (per kg) in the damp clothes.
Gentleness (10%): Calculated from the amount of wear on easily frayed squares of cloth.
Energy efficiency (50%): calculated from the amount of energy used to dry 1kg of wet clothes.
Drying time (50%): based on the time it takes to dry 1kg of wet clothes.
The maximum noise level is recorded during the spin cycle and is measured one metre away from the machine and one metre above the ground.
We ask our members whether they've had any problems with their washers, and whether they'd buy the same brand again. To see which brands fared best, go to the reliability and satisfaction scores here.
We've tested 10 washer-dryers.
