Model
Bluestar BS24DW
Rank #104 means 103 of the 709 dishwasher models we track cost less to run each year; the 44th efficiency percentile means it uses less energy for its size than 44% of those models.
What does the Bluestar BS24DW cost to run per year?
Among the 709 dishwasher models we track, the Bluestar BS24DW's $42/yr running cost ranks it #104, comfortably in the cheap-to-run group. It uses 26.7% less energy than the U.S. federal standard model in its class, which would cost about $57/yr to run, a saving of roughly $15 a year. Capacity-normalized, it ranks ahead of 44% of dishwasher models we track, right in the class's middle band. This class has no published efficiency-factor figure beyond annual kWh itself, so at 12 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 Blomberg DWT 81900 **** at $42/yr runs a little cheaper and the Bosch SHP65DC** at $42/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 Bluestar BS24DW's $42/yr adds up to roughly $378 in electricity alone, before purchase price or repairs.

By the numbers
The Bluestar BS24DW 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 $42/yr, here is what the Bluestar BS24DW adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Bluestar BS24DW costs about $420. That is roughly $150 less than a standard model in its class, which would run closer to $570 over the same ten years.
How the Bluestar BS24DW compares
The dishwasher class we track runs from $15 to $45 a year. At $42/yr, it runs about $2 a year cheaper than the class median of $44, and it is about $27 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 Bluestar BS24DW uses 26.7% less energy.
What drives its running cost
At 12 place settings, the Bluestar BS24DW is a small dishwasher for its class, which spans 2 to 18 place settings with a median of 14 place settings, and smaller dishwasher models generally cost less to run for the same job, all else being equal.
- 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 Bluestar BS24DW cheap to run?
Yes. Its $42/yr running cost puts it at rank #104 of 709, below what most dishwasher models we track cost to run.
How much does the Bluestar BS24DW cost per month?
About $3.48 a month, which is the $42 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: 225 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $42 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Bluestar BS24DW for its size?
44th percentile once size is factored in. That means its size-adjusted efficiency is not the main reason for the running-cost figure above; its capacity plays a large role too.
