About the LG SIGNATURE SDNVH981 series
The LG SIGNATURE SDNVH981 series is a 16 place settings standard dishwasher certified by ENERGY STAR. Its official test figure is 220 kWh of electricity a year, which at the U.S. average price of 18.19¢ per kWh comes to $40 a year, or $400 over a typical 10-year life.
That is 28% less energy than the federal maximum for this type of dishwasher (307 kWh a year), a saving of about $16 a year compared with a model that only just meets the standard.
Among 616 standard models it ranks #64 for running cost. The cheapest model of this type would save $36 in electricity over 10 years, though it may differ in size and features.
If you want the same type and a similar size for less to run, the Fisher & Paykel DD24DTX6I1 uses 202 kWh a year and would save about $33 over 10 years.
