GE GDF46Z Running Cost (Dishwasher)
GE GDF46Z: running cost
At 240 kWh/yr, the GE GDF46Z's ENERGY STAR certification puts it about average for its category to run against every other certified dishwasher.
That $45 is priced at 18.8¢/kWh, the average of all 51 state rates this site tracks. Your own state's rate is one click away.
How the GE GDF46Z compares to other dishwashers
The category average is 232 kWh/yr; this model runs 3.4% above it, ranking 530 of 737 dishwashers tracked here for running cost. 737 certified dishwashers, one average, about $2/year of daylight between it and this model; the full methodology has the rest.
Neighbouring models
Right next to the GE GDF46Z on that list: GE GDF46T ($45/yr, 240 kWh/yr) runs slightly less, while GE GDF51R ($45/yr, 240 kWh/yr) runs slightly more.
Comparing GE's own models
Ranked 15 of GE's 41 certified dishwashers, this sits between the GBF180SM ($44/yr, the brand's cheapest) and the UDT16V ($45/yr, its priciest).
GE GDF46Z over 9 years
NAHB's Study of Life Expectancy of Home Components puts a typical dishwasher's service life at 9 years; run the GE GDF46Z that long and it costs about $406 in electricity, on top of whatever it cost to buy.
Weighing a replacement
Efficient as certified dishwashers go, $45/year is a reasonable baseline if you're comparing what else is on the market.

If you're keeping it
The GE GDF46Z already costs $45/year to run; a repair bill on top of that is the kind of expense a protection plan exists to smooth out.
How this was checked
Two sourced numbers, nothing modeled: ENERGY STAR's certified kWh/yr for this exact model, and EIA's published state electricity rate. The full Dishwasher category page shows all 737 dishwashers ranked by cost; the state-rate guide covers the half of this number that isn't the appliance.
