Laundry · Decision guide
For normally soiled laundry that can be washed at 40°C or 60°C, Eco 40-60 is the sensible efficiency-focused choice. A quick programme is useful when you have a small, lightly soiled load and saving time matters more than optimising consumption.

Why does Eco 40-60 take so long?
Cycle duration is not the same thing as energy consumption. Heating water accounts for a substantial part of a washing machine's energy use. Eco programmes can use a lower effective washing temperature and more time to achieve the required cleaning performance with less energy.
The European Commission requires modern washing machines to provide an Eco 40-60 programme that can clean normally soiled cotton items declared washable at 40°C or 60°C together in the same cycle. The programme is subject to requirements covering washing performance, rinsing effectiveness, duration, energy and water use.
What does the EU label actually show?
Since 1 March 2021, EU washing-machine labels use an A-to-G scale. Among other figures, the label shows energy use per 100 cycles, water use per cycle and programme duration. These values are based on Eco 40-60. That matters because you cannot assume a quick cycle uses less energy simply because it runs for fewer minutes.
Practical rule: when comparing two machines for efficiency, use their label and EPREL figures. When selecting a programme for today's laundry, use fabric type, soil level, load size and the appliance manual.
When does quick wash make sense?
Short programmes are most useful for small amounts of lightly soiled clothing that need a fast refresh. The permitted load, temperature and duration are model-specific. On some machines a 15-minute programme is intended only for a very small load; others provide 30- or 60-minute variants.
For that reason, universal claims such as “Quick always uses more” or “Quick is always more efficient” are misleading. Manufacturers use different temperatures, load limits, water quantities and control logic. Compare the actual programmes on your machine.
Do not overload the Eco programme
Eco 40-60 is designed around defined load conditions and the machine may adapt water, time and temperature. But physically stuffing the drum too tightly reduces textile movement and can hurt cleaning performance. Follow the maximum programme load in the manual.
What about 20°C?
EU ecodesign rules also require a programme called “20°C”, intended for lightly soiled cotton laundry at a nominal temperature of 20°C. It is separate from Eco 40-60. For lightly soiled garments that do not require a hotter wash, it can be a sensible option when compatible with the care label and appliance instructions.
Bottom line
Eco 40-60 is a good default for normally soiled cotton when time is not critical. Quick wash is a tool for small, lightly soiled loads and situations where speed is the priority. Do not judge efficiency by minutes: for model-to-model comparison, use the kWh/100 cycles and litres/cycle figures on the EU label.
