Model
Asko DFI786*
Rank #134 means 133 of the 709 dishwasher models we track cost less to run each year; the 100th efficiency percentile means it uses less energy for its size than 100% of those models.
What does the Asko DFI786* cost to run per year?
Rank #134 of 709 puts the Asko DFI786* among the cheapest dishwasher models we track to keep running, at roughly $43 a year. It uses 25.1% 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. Its size-adjusted efficiency percentile of 100 means the low running cost is not just a function of size; almost nothing in the class beats it on efficiency once capacity is accounted for. This class has no published efficiency-factor figure beyond annual kWh itself, so at 18 place settings (the class spans 2 to 18), size is the clearest lever we can point to for this model's running cost.
Immediately around it on the leaderboard, the Asko DBI786* at $43/yr runs a little cheaper and the Beko DDT38532*** 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 Asko DFI786*'s $43/yr adds up to roughly $387 in electricity alone, before purchase price or repairs.

By the numbers
The Asko DFI786* 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 Asko DFI786* adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Asko DFI786* 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 Asko DFI786* 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 Asko DFI786* uses 25.1% less energy.
What drives its running cost
At 18 place settings, the Asko DFI786* is a large dishwasher for its class, which spans 2 to 18 place settings with a median of 14 place settings, size is usually the single biggest lever behind a running-cost figure, and at this end of the range there is more capacity to service, which tends to push the number up.
- Place-setting capacity. Place-setting capacity is the main driver of how much water a cycle has to heat, and heating that water is most of a dishwasher's electricity use.
- Water heating. Most dishwashers have a booster heater that raises incoming water to sanitizing temperature; this heating step, not the pump or motor, accounts for most of a cycle's electricity use.
- Cycle length and drying method. Heavy or sanitize cycles run longer and hotter than a normal or eco cycle, and heated-dry options cost more to run than air-dry or condensation drying.
Common questions
Is the Asko DFI786* cheap to run?
Yes. Its $43/yr running cost puts it at rank #134 of 709, below what most dishwasher models we track cost to run.
How much does the Asko DFI786* cost per month?
About $3.56 a month, which is the $43 annual estimate spread across twelve months at the US average rate of $0.1856/kWh. Your own bill scales with your local electricity rate and how heavily you use it.
How is this running-cost figure calculated?
The formula is annual kWh times price per kWh: 230 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $43 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Asko DFI786* for its size?
100th percentile once size is factored in. That means its size-adjusted efficiency is a real factor in the running-cost figure above; its capacity plays a large role too.
