Model
Summit Professional DW2435SS
Rank #181 means 180 of the 709 dishwasher models we track cost less to run each year; the 40th efficiency percentile means it uses less energy for its size than 40% of those models.
What does the Summit Professional DW2435SS cost to run per year?
At about $43 a year, the Summit Professional DW2435SS undercuts most dishwasher models we track on running cost, rank #181 of 709. 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. Efficiency-wise, once size is accounted for, it sits right around the class median, ahead of 40% of the models we track. 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 Summit LDW24WA at $43/yr runs a little cheaper and the Unique UNQ-DW24CT PR 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 Summit Professional DW2435SS's $43/yr adds up to roughly $387 in electricity alone, before purchase price or repairs.

By the numbers
The Summit Professional DW2435SS 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 Summit Professional DW2435SS adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Summit Professional DW2435SS 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 Summit Professional DW2435SS 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 Summit Professional DW2435SS uses 23.8% less energy.
What drives its running cost
At 12 place settings, the Summit Professional DW2435SS 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 Summit Professional DW2435SS cheap to run?
Yes. Its $43/yr running cost puts it at rank #181 of 709, below what most dishwasher models we track cost to run.
How much does the Summit Professional DW2435SS cost per month?
About $3.62 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: 234 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 Summit Professional DW2435SS for its size?
40th percentile once size is factored in, a fairly typical result for the class.
