How Much Does It Cost to Run a Dishwasher in Australia? (2026)
A dishwasher draws heavy power only while heating water and during the drying phase. Over a full cycle it averages 1 to 2 kWh, which is usually cheaper than washing the same dishes by hand with hot water.
A typical dishwasher (1,500 W) costs A$0.52 per hour, or about A$15.75 per month at 1 hours a day in Australia. Average running cost
| Wattage | Per hour | Per day | Per month | Per year |
|---|---|---|---|---|
| Low (1,200 W) | A$0.42 | A$0.42 | A$12.60 | A$153.30 |
| Typical (1,500 W) | A$0.52 | A$0.52 | A$15.75 | A$191.62 |
| High (2,400 W) | A$0.84 | A$0.84 | A$25.20 | A$306.60 |
Formula: watts ÷ 1000 × hours × price per kWh. Typical use is 1 h/day ≈ 548 kWh per year.
In Australia, with electricity at A$0.35 per kWh (source: AER Default Market Offer 2026–27, 2026-07), a typical dishwasher costs A$0.52 per hour and about A$191.62 per year at 1 hours a day. Each A$1.00 of electricity buys roughly 1.9 hours of use.
How to lower the cost of running a dishwasher
- Skip the heated dry option and open the door at the end of the cycle instead.
- Only run full loads, and use the eco program.
- Scrape plates but do not pre-rinse under hot water.
- Connect to cold water if your dishwasher has its own heater and your hot water is electric.
In standby it draws about 1 W, which adds roughly 9 kWh (A$3.07) per year if it is never unplugged.

About 1 to 1.5 kWh per cycle on a normal program. Use the hourly figure above as a per-cycle estimate.
