Washing machine Power consumption formula:

A washing machine is another house hole electrical equipment used for washing the clothes. Washing machine power consumption in kWh is equal to the product of the wattage and the operating hours divided by 1000. The formula can be written as,

kWh = Wattage x operating hour / 1000.

For calculating monthly consumption is equal to the 30 times of daily consumption.

kWh Monthly = 30 x Wattage x operating hour / 1000.

For yearly consumption is equal to the 365 times of the daily consumption.

kWh Monthly = 365 x Wattage x operating hour / 1000.

In case if you operate a washing machine based on minutes means, the power consumption formula will be changed,

kWh = Wattage x operating minutes / 60,000

The washing machine power consumption is equal to the operating minutes times of the wattage divided by 60000.

Washing machine Power Consumption Calculation:

Let we calculate the power consumption of Bosch 7 kg Fully-Automatic Front Loading Washing Machine (WAK24168IN, Silver, Inbuilt Heater)Amazon and it operated 45 minutes per day.

According to the datasheet, the washing machine consumes 2400 watts per hours. look at the table of power consumption per day, per month and per year.

Washing machine Power Consumption -45 minutes
 Consumption Total (Wh) kWh
Hourly 2400 2.4
Day 1800 1.8
Month 54000 54
Yearly 648000 648

Hence our total electricity consumption per year will be 648 kWh or 648 units

For calculating the electricity bill, we need to multiply the total units by the per-unit rates.

LG washing machine power consumption:

LG washing machine is available up to 10kG for both semi-automation and fully auto machine. Let us calculate the electricity consumption of both semi and fully automation washing machine.

LG Semi automation washing machine:

Semi automation is nothing but you need to perform all the work by manually, i.e pouring the water, and drying. The main advantage is, the machine comes with low cost typically 8000/- to 20,000 and it much cheaper than the full automation machine by 50%.

Take LG 8 Kg 5 Star Semi-Automatic Top Loading Washing Machine (P8035SGMZ, Grey, Collar Scrubber) runs 30 minutes per day and calculate the electricity consumption.

According to it is datasheet, the washing machine consumes 2900 watts per hour.

Semi-Automatic Washing machine Power Consumption -30 minutes
 Consumption Total (Wh) kWh
Hourly 2900 2.9
Day 1450 1.45
Month 43500 43.5
Yearly 522000 522

 

Look at the table, the washing machine consumes 261 units per year while using the washing machine.

LG Fully automation washing machine power Consumption:

LG Fully automatic machine wattage

The fully automatic machine comes with the automatic function of water filling, cloth drying, power resume option etc.

For calculating electricity consumption, let we take LG 8.0 Kg Fully-Automatic Top Loading Washing Machine (F12U1TCN4, Middle Free Silver), which operates 30 minutes per day.

According to its datasheet, the LG washing machine consumes, 2100 Watts per hour. But we are operating the machine by 30 minutes, hence the per day power consumption will be 1050 Watts hour converting it into the unit, it comes 1.05 units.

Fully Automatic Washing machine Power Consumption -30 minutes
 Consumption Total (Wh) kWh
Hourly 2100 2.1
Day 1050 1.05
Month 31500 31.5
Yearly 378000 378

Hence your net power consumption will be 378 units per year.

IFB Washing Machine Power Consumption:

Let we calculate another example of 6.5 KG IFB washing machine power consumption per day, per month and per year and electricity bill per day, per month and per year. The machine operates 45 minutes per day and considers the per unit tariff as 4.5/-.

According to its technical sheet, the washing machine consumes 2200 Watts per hour.

IFB Washing Machine Power Consumption -45 minutes
 Consumption Total (Wh) kWh Bill
Hourly 2200 2.2 9.9
Day 1650 1.65 7.425
Month 49500 49.5 222.75
Yearly 594000 594 2673

Look at the above table of consumption, the machine consumes 594 units per year while operating 45 minutes per day.

Washing Machine Power Saving Tips:

A washing machine is a technology used for washing clothes and it contributes almost 10% of your electricity consumption. However, you can save electricity consumption by following the below mentioned.

  1. Avoid water extraction by washing machine: By that way, you can reduce almost 50% of your electricity. After completion of washing, just take the clothes from the machine spin it by yourself and put them in sun sight.
  2. Never use hot water for washing your clothes, since hot water takes much longer cycle for washing your clothes. According to BEE, higher washing time causes higher electricity consumption.
  3. Buy 5-star rating washing machine, for example, 5 stars LG 7 KG front load consumes 0.09 kWh per cycle but the same 7kG LG 4-star washing machine consumes 0.105 kWh per cycle. Almost you get 15% of energy saving by buying a 5-star washing machine.
  4. The number of cycle increases the power consumption hence avoid more number of cycle.
  5. Do not run the machine under load, wait to get full load the machine. (Run your machine on the shortest cycle).
  6. Switch off the Machine: The machine consumes 5 to 10 watts during offline, hence unplug the machine after completion of cloth washing.
