Check the energy label on your chosen LG washing machine for a series of stars, plus a number that tells you the estimated annual energy consumption (kWh/per year) it uses to run. More stars means a more energy-efficient machine, however for consistency you should only compare star ratings and energy consumption between machines of the same capacity and loading type.
At the top of the water rating label, the star rating shows the water efficiency of the product. Understanding the star rating is easy — the more stars, the more water efficient the product is. Use the star rating to compare the water efficiency of different products at a glance. The middle section of the label shows the amount of water used by the product, in which consumption rate details vary by product type. You should only compare star rating and energy consumption between the machines of same capacity and loading type.
