Same brand, different models
LG makes 93 ENERGY STAR certified washing machines; this one ranks 83 of 93 for running cost, between the brand's cheapest, the WM3420C at $15/yr, and its priciest, the WT7485C at $41/yr.
Cost over its typical lifespan
Over the 10-year service life NAHB reports for this category, running the LG WT7900HA costs roughly $282 in electricity, separate from the purchase price.
Shopping for a new one
The LG WT7900HA runs above its category average. If the washing machine you actually own is older still, likely well past ENERGY STAR's efficiency baseline when it was made, a current certified model could cost meaningfully less than this model's $28/year every year.
