Washing machine settings, explained

A washing machine has more settings than most people ever touch, and the labels on the dial don't explain themselves. This is what each one does, when it matters, and how to turn the symbols on a care label into a setting you can trust.

The three that matter most

• Temperature — the water temperature, and the biggest factor in shrinkage, dye bleeding and energy use. The care label gives the maximum; our wash temperature guide covers how to choose within it.
• Cycle — how vigorously the drum moves and for how long. The bars under the label's tub symbol tell you how gentle it needs to be; see the wash cycle guide.
• Spin speed — how fast the drum turns at the end to throw water out, given in revolutions per minute. More speed means drier clothes and shorter drying, but more creasing and more stress on fabric. Use the machine's fastest spin for towels and sturdy cottons, a middle setting for everyday clothes and shirts, and the lowest for knits and delicates.

The optional extras

• Extra rinse. One more rinse to clear detergent residue. Worth it for sensitive skin, for baby clothes, for towels (residue makes them stiff and less absorbent) and for any load where you've used more detergent than usual.
• Prewash. A short wash before the main one. Useful only for heavily soiled loads — muddy sportswear, workwear. On ordinary laundry it adds time and water for nothing.
• Soak. Holds the load in water before agitating. Helps with set-in dirt and some stains; not for wool or silk, which weaken when soaked.
• Eco. A longer, cooler wash that cleans by giving the detergent time rather than heat.
• Delay start. Starts the cycle later, so a load finishes when you're there to hang it — clothes left wet in the drum for hours are where musty smells come from.
• Steam, allergy or hygiene programs. Hotter, longer cycles for bedding and towels. Only for fabrics whose labels allow high temperatures.

Load size and water

Clothes clean by moving through water. A drum packed tight leaves the middle of the load barely wet and the edges scrubbing against each other. A useful rule: when the drum is loaded, you should still be able to fit a hand flat on top of the clothes. Most modern machines weigh the load and set the water level themselves; older ones need the load-size setting to match.

Detergent dose

More detergent doesn't mean cleaner clothes. Beyond the amount the water can rinse out, the surplus stays in the fabric — it's what makes towels stiff, dark clothes look dusty and skin itch. Dose by the guidance on the pack for your load size and water hardness, and use less rather than more if you're unsure. Front-loading and high-efficiency machines need a low-sudsing detergent marked for them; ordinary detergent foams too much for the small amount of water they use.

Building a setting from a care label

Read the symbols in order and each one fills in a setting:

• The number in the tub is your maximum temperature. Go lower for darks, synthetics and anything new.
• The bars under the tub pick the cycle: none for normal, one for permanent press or synthetics, two for delicate or wool.
• The fabric picks the spin: fast for cotton and linen, medium for blends and shirts, slow for wool, silk and anything that creases badly.

So a cotton T-shirt marked 40 with one bar becomes a 40 °C synthetics cycle at a medium spin, and a wool sweater with the hand-wash symbol becomes the wool program, cold, on the lowest spin. Every symbol is explained in the laundry symbol guide.

LaundryMax does this reading for you: it groups your garments into loads that share a temperature and cycle, and its machine screen keeps the temperature, cycle and spin for each load, so you set the machine once per load instead of once per garment. See how it works.
