A Hidden Button on Washing Machines Can Reduce Electricity Costs by Up to 62% — Experts Explain Why

Many households don't realize that their washing machine contains a “hidden feature” that can significantly reduce energy consumption. According to appliance technicians, using this function correctly can help families save up to 62% on electricity costs each month — without buying any new equipment.

Most people use washing machines the wrong way

Washing machines today come with many built-in modes, but the majority of users only rely on the standard wash cycle. This causes the machine to run longer, heat more water, and consume more power than necessary. Over time, the wasted energy becomes substantial.

That is why experts emphasize a little-known button: the “Eco Mode” (Energy-Saving Mode).

Why does Eco Mode save so much power?

Eco Mode is programmed to optimize water use, reduce drum speed, and minimize heating — the part of the wash cycle that uses the most electricity. Even though the cycle may run slightly longer, total energy consumption drops sharply.

Appliance engineers breakdown the savings as follows:

• Heating water accounts for 70–90% of a washing machine’s electricity use.

• Eco Mode lowers the water temperature, cutting power needed for heating.

• It also reduces the amount of water used per cycle by up to 40%.

• The drum rotates more efficiently, using less motor power.

This combination results in an average energy reduction of 50–62%, depending on the model.

Who should use Eco Mode?

Eco Mode is ideal for:

• Daily laundry like T-shirts, jeans, underwear, socks

• Lightly soiled clothing

• Families who wash frequently

• Anyone trying to reduce monthly electricity bills

However, Eco Mode is not recommended for heavily stained clothes, thick blankets, or items requiring hot water to disinfect.

Other tips to further reduce energy use

Experts also recommend:

• Washing full loads instead of many small loads

• Using cold water washes when possible

• Cleaning the machine’s filter once a month to improve efficiency

• Avoiding the dryer when you can air-dry clothes

When combined, these habits can drop overall laundry-related electricity usage by nearly 70%.

A small button, big savings

Many households unknowingly overlook Eco Mode simply because they never read the manual or assume it’s unnecessary. But with rising electricity costs, this “hidden button” is becoming one of the easiest hacks to save money without sacrificing cleanliness.

If your washing machine has Eco Mode, experts say: Use it — your electricity bill will thank you.
