Model
Fisher & Paykel DD24SCTX9
Rank #7 means 6 of the 709 dishwasher models we track cost less to run each year; the 42nd efficiency percentile means it uses less energy for its size than 42% of those models.
What does the Fisher & Paykel DD24SCTX9 cost to run per year?
Almost nothing we track in this class costs less to run than the Fisher & Paykel DD24SCTX9: about $25 a year, rank #7 of 709. It uses 39.6% less energy than the U.S. federal standard model in its class, which would cost about $41/yr to run, a saving of roughly $16 a year. Adjusted for size, it is more efficient than 42% of dishwasher models we track, a middling result. At 7 place settings, it is a small 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 Fisher & Paykel DD24SAX9 at $25/yr runs a little cheaper and the Fisher & Paykel DD24SDFTX9 at $25/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 DD24SCTX9's $25/yr adds up to roughly $225 in electricity alone, before purchase price or repairs. At rank #7 of 709, it is one of the single cheapest dishwasher models we track to run, in the top one percent on cost.

By the numbers
The Fisher & Paykel DD24SCTX9 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 $25/yr, here is what the Fisher & Paykel DD24SCTX9 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 DD24SCTX9 costs about $250. That is roughly $160 less than a standard model in its class, which would run closer to $410 over the same ten years.
How the Fisher & Paykel DD24SCTX9 compares
The dishwasher class we track runs from $15 to $45 a year. At $25/yr, it runs about $19 a year cheaper than the class median of $44, and it is about $10 a year more than the cheapest dishwasher to run at $15. Against the US federal standard model for its class at about $41/yr, the Fisher & Paykel DD24SCTX9 uses 39.6% less energy.
What drives its running cost
At 7 place settings, the Fisher & Paykel DD24SCTX9 is a small dishwasher for its class, which spans 2 to 18 place settings with a median of 14 place settings, at the small end of the class, capacity itself is doing a lot of the work to keep that figure down, separate from how efficient the unit actually is.
- 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 Fisher & Paykel DD24SCTX9 cheap to run?
Yes, relatively. At $25 a year it ranks #7 of 709 dishwasher models we track, in the cheaper part of its class to run.
How much does the Fisher & Paykel DD24SCTX9 cost per month?
Roughly $2.07/mo, spreading the $25/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 134 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $25 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Fisher & Paykel DD24SCTX9 for its size?
42nd 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.
