Model
Blomberg DWDI56310
Rank #127 means 126 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 Blomberg DWDI56310 cost to run per year?
Do the math and the Blomberg DWDI56310's $43/yr puts it at rank #127 of 709, one of the more affordable dishwasher models we track to keep running. It uses 25.4% 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. Normalized for capacity, it beats 77% of dishwasher models we track, a better-than-average efficiency result. 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 Viking VDWU524SS at $42/yr runs a little cheaper and the Blomberg DWDT56310X 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 Blomberg DWDI56310's $43/yr adds up to roughly $387 in electricity alone, before purchase price or repairs.

By the numbers
The Blomberg DWDI56310 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 Blomberg DWDI56310 adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Blomberg DWDI56310 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 Blomberg DWDI56310 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 Blomberg DWDI56310 uses 25.4% less energy.
What drives its running cost
At 15 place settings, the Blomberg DWDI56310 is a mid-size dishwasher for its class, which spans 2 to 18 place settings with a median of 14 place settings, right in the middle of the capacity range, so capacity is roughly a wash compared with the rest of the class.
- 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 Blomberg DWDI56310 cheap to run?
Yes, relatively. At $43 a year it ranks #127 of 709 dishwasher models we track, in the cheaper part of its class to run.
How much does the Blomberg DWDI56310 cost per month?
Roughly $3.54/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 229 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 Blomberg DWDI56310 for its size?
77th 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.
