Washer dryer buying guide: how to choose

A washer dryer combines two functions in a single appliance, but performance varies significantly between models. Washing capacity, energy and water consumption, and noise level determine efficiency and daily comfort.

What to check

Washing capacity Washing capacity indicates the maximum amount of laundry you can wash in a single load, expressed in kilograms. This criterion determines the appliance’s autonomy and how many cycles you’ll need each week. In the current market, capacities range from seven to twelve kilograms, with a median of nine kilograms. A generous capacity suits large families or those washing bulky items like duvets. On Kalyneo, a long bar indicates high capacity. Note that drying capacity is typically lower than washing capacity. Market median: 9 kg
Energy consumption in washing Energy consumption measures the electricity needed for one hundred washing cycles, expressed in kilowatt-hours. This criterion directly affects your annual bill and environmental footprint. Recent models display consumptions ranging from thirty-three to fifty-seven kilowatt-hours per hundred cycles, with a median around forty-four and a half kilowatt-hours. The most efficient appliances significantly reduce expenses over the equipment’s lifetime. On Kalyneo, a long bar indicates low consumption, thus better energy efficiency. Prioritize efficient models if you wash frequently. Market median: 44.5 kWh
Water consumption per cycle Water consumption per washing cycle measures the amount of water used for a complete wash, in litres. This criterion impacts both your water bill and resource conservation. Washer dryers on the market consume between thirty-six and fifty-seven litres per cycle, with half the models around forty-five and a half litres. Efficient appliances limit waste without compromising wash quality. On Kalyneo, a long bar indicates low water consumption. If you use the appliance daily, every litre saved counts over the year. Market median: 45.5 L
Noise level during spinning Noise level during spinning measures the sound produced during the loudest phase of the cycle, expressed in decibels. This criterion determines your acoustic comfort, especially if the appliance is located near living areas or operates in the evening. Recent models display levels ranging from seventy to seventy-six decibels, with a median of seventy-two decibels. The quietest appliances allow you to start a cycle without disrupting household activities. On Kalyneo, a long bar indicates low noise level, thus a discreet appliance. Every decibel counts in an open space. Market median: 72 dB
Installation and connections A washer dryer requires connection to cold water supply and drainage, as well as a suitable electrical outlet. Check the dimensions of the appliance and the intended location, accounting for door opening and access to controls. Some models can be built under a worktop. Ensure a stable, level floor to limit vibrations. The appliance must be placed in a ventilated space, as the drying function generates heat and humidity.

What you get for each budget

Under €600

Models in this range offer modest capacities, around seven to eight kilograms, with energy and water consumptions in the higher market average, and often noticeable noise levels.

€600 to €900

This range offers a good balance between washing capacity, typically nine to ten kilograms, and controlled consumption, with acceptable noise levels for daily use.

Over €900

Premium appliances combine generous capacities of eleven to twelve kilograms, optimized energy and water consumption, and particularly quiet operation, suited to intensive use.

Frequent mistakes

Confusing washing capacity with drying capacity, often half as much.
Neglecting noise level if the appliance is installed near bedrooms or living room.
Underestimating the impact of energy and water consumption on annual budget.
Forgetting to measure available space, accounting for door opening.
