Model
Smeg DW8600
Rank #174 means 173 of the 709 dishwasher models we track cost less to run each year; the 77th efficiency percentile means it uses less energy for its size than 77% of those models.
What does the Smeg DW8600 cost to run per year?
At $43 a year to run, the Smeg DW8600 runs cheaper than most models in its class, ranking #174 of 709 dishwasher models we track. It uses 23.8% less energy than the U.S. federal standard model in its class, which would cost about $57/yr to run, a saving of roughly $14 a year. Once capacity is factored in, its 77th efficiency percentile puts it ahead of most peers in its class. At 15 place settings, it is a mid-size dishwasher for the class, which runs 2 to 18 place settings; size and efficiency are the two levers behind the figure above, and this dataset does not carry a separate efficiency-factor column for this class.
Immediately around it on the leaderboard, the Savalo SDW50012PR at $43/yr runs a little cheaper and the Smeg DW8601 at $43/yr runs a little more, a sense of how tightly models are packed at this point in the ranking. A dishwasher typically stays in service for somewhere around 9 years; over that span, the Smeg DW8600's $43/yr adds up to roughly $387 in electricity alone, before purchase price or repairs.

By the numbers
The Smeg DW8600 normalized against its whole class, so each figure means something.
What it costs you over time
Running cost is an every-year number, so it compounds. At $43/yr, here is what the Smeg DW8600 adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Smeg DW8600 costs about $430. That is roughly $140 less than a standard model in its class, which would run closer to $570 over the same ten years.
How the Smeg DW8600 compares
The dishwasher class we track runs from $15 to $45 a year. At $43/yr, it runs about $1 a year cheaper than the class median of $44, and it is about $28 a year more than the cheapest dishwasher to run at $15. Against the US federal standard model for its class at about $57/yr, the Smeg DW8600 uses 23.8% less energy.
What drives its running cost
At 15 place settings, the Smeg DW8600 is a mid-size dishwasher for its class, which spans 2 to 18 place settings with a median of 14 place settings, putting it squarely in the middle of the class on the size lever that drives most of the cost.
- Place-setting capacity. A larger dishwasher heats more water per cycle, so bigger capacity generally means a higher annual energy figure, independent of how efficient the unit is.
- Water heating. The booster heater that brings water up to sanitizing temperature is usually the single largest electrical load in a dishwasher's cycle.
- Cycle length and drying method. Cycle selection, eco versus heavy, air-dry versus heated-dry, moves real running cost more than most owners realize for a given capacity.
Common questions
Is the Smeg DW8600 cheap to run?
Yes, relatively. At $43 a year it ranks #174 of 709 dishwasher models we track, in the cheaper part of its class to run.
How much does the Smeg DW8600 cost per month?
Roughly $3.62/mo, spreading the $43/yr estimate evenly across twelve months at $0.1856/kWh. Actual monthly bills swing with your rate and usage pattern.
How is this running-cost figure calculated?
We take the model's published annual energy use of 234 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $43 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Smeg DW8600 for its size?
77th percentile once size is factored in, a fairly typical result for the class.
