Washing Machine Energy-Saving Secrets: 3 Settings Most People Don't Know About
When paying my electricity bill recently, I noticed something strange:
Only two people in my home, yet monthly utilities cost over 200 yuan.
Looking closer at the bill, I found the washing machine was a “power hog.” Each wash used about 1 kWh, costing over 30 yuan monthly just for laundry.
Then I studied how to use the machine properly and discovered I’d been “using it wrong.” After adjusting a few settings, I saved over 20 yuan monthly.
Today I’ll share 3 energy and water-saving tips most people don’t know.
Tip 1: Water Level Isn’t “Higher Is Better”
I used to always set water level to maximum, thinking more water meant cleaner clothes.
Turns out, too much water actually makes clothes less clean. Fabrics float, reducing friction and cleaning power.
Correct approach:
- Small loads (3 items or less): Select “low water level” or “small load”
- Medium loads (4-6 items): Select “medium water level”
- Large loads (7+ items): Select “high water level”
I tested this: low water level uses about 40% less water than high. If each wash uses 50 liters, low level only needs 30. Ten washes a month saves 200 liters.
Plus, low water level doesn’t compromise cleaning. More friction between clothes actually cleans better.
Tip 2: Don’t Blindly Chase “High Temperature”
Many people think hot water cleans better, so they set washer temperature to maximum.
Actually, most daily laundry is fine with room temperature water. Only sheets, towels, and underwear needing disinfection require water above 60°C.
Correct approach:
- Daily clothes (t-shirts, pants): Room temperature (20-30°C)
- Stubborn stains: 40°C warm water
- Items needing disinfection (sheets, underwear): 60°C+
Heating water consumes enormous electricity. I calculated:
- Room temperature wash: 0.3 kWh per load
- 60°C hot water wash: 1.2 kWh per load
That’s 4 times the difference. Ten washes monthly at room temperature saves 9 kWh—about 5 yuan.
Tip 3: Spin Speed Isn’t “Faster Is Better”
Many think faster spinning means faster drying, so they max out RPM.
Actually, overly high spin speeds waste electricity and damage fabric fibers.
Correct approach:
- Light fabrics (shirts, t-shirts): 800-1000 RPM
- Heavy fabrics (jeans, jackets): 1000-1200 RPM
- Delicate items (sweaters, knits): 600-800 RPM
I used to wash sweaters at 1200 RPM and they got misshapen. At 800 RPM, drying speed is fine and clothes are protected.
Lower spin speeds save about 0.1 kWh per load. Small savings add up.
My Current Habits
Now my washing machine routine:
- Choose water level by load size: Small loads use low level, large loads high
- Daily clothes at room temperature: Only sheets use hot water
- Set spin speed by fabric type: Thin items 800 RPM, thick items 1200 RPM
After adjusting these three settings, my monthly electricity bill dropped from over 200 to around 180. Water bill saved about 10 yuan too.
Combined savings: over 30 yuan monthly, over 300 yuan yearly.
Not huge, but these are just setting adjustments requiring zero effort. Saved money—even if just for some fruit—is real benefit.
