Model
Fisher&Paykel DW24UNT4X2
Rank #41 means 40 of the 709 dishwasher models we track cost less to run each year; the 92nd efficiency percentile means it uses less energy for its size than 92% of those models.
What does the Fisher&Paykel DW24UNT4X2 cost to run per year?
The Fisher&Paykel DW24UNT4X2 holds rank #41 of 709 on running cost, at about $39 a year, a genuinely cheap result for the class. It uses 31.6% less energy than the U.S. federal standard model in its class, which would cost about $57/yr to run, a saving of roughly $18 a year. Its size-adjusted efficiency percentile of 92 means the low running cost is not just a function of size; it is genuinely efficient for its class. This class has no published efficiency-factor figure beyond annual kWh itself, so at 15 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 Fisher & Paykel DW24UT2I3 at $39/yr runs a little cheaper and the Fisher&Paykel DW24UT4I2 at $39/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 Fisher&Paykel DW24UNT4X2's $39/yr adds up to roughly $351 in electricity alone, before purchase price or repairs.

By the numbers
The Fisher&Paykel DW24UNT4X2 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 $39/yr, here is what the Fisher&Paykel DW24UNT4X2 adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Fisher&Paykel DW24UNT4X2 costs about $390. That is roughly $180 less than a standard model in its class, which would run closer to $570 over the same ten years.
How the Fisher&Paykel DW24UNT4X2 compares
The dishwasher class we track runs from $15 to $45 a year. At $39/yr, it runs about $5 a year cheaper than the class median of $44, and it is about $24 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 Fisher&Paykel DW24UNT4X2 uses 31.6% less energy.
What drives its running cost
At 15 place settings, the Fisher&Paykel DW24UNT4X2 is a mid-size dishwasher for its class, which spans 2 to 18 place settings with a median of 14 place settings, neither the size advantage of a small unit nor the size penalty of a large one applies here, so its running cost is a fairer test of efficiency alone.
- 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 Fisher&Paykel DW24UNT4X2 cheap to run?
Yes. Its $39/yr running cost puts it at rank #41 of 709, below what most dishwasher models we track cost to run.
How much does the Fisher&Paykel DW24UNT4X2 cost per month?
About $3.25 a month, which is the $39 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: 210 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $39 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Fisher&Paykel DW24UNT4X2 for its size?
92nd 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.
