Modern dishwashers are a lifesaver in the kitchen, but they’re not exactly shy about using electricity. While most newer models are more efficient than hand-washing, there’s a little-known accessory that can make them even less power-hungry — and it’s as simple as placing it inside the machine before you press start.
The secret accessory: the eco-disc
If you’ve never heard of an eco-disc, you’re not alone. These small devices, usually made from plastic or metal, are designed to be placed inside your dishwasher during a wash cycle. Their purpose? To optimise water flow so every spray is used more efficiently.
By subtly redirecting the water jets, eco-discs help ensure every plate, glass, and fork gets a thorough clean without the machine having to work as hard. That improved water distribution can reduce the energy required to heat and pump water — which, over time, means lower power bills and a smaller environmental footprint.
How much energy does a dishwasher use?
A dishwasher’s energy consumption depends on factors like the model, brand, capacity, age, and the programs you run most often. On average:
- Standard models use between 1.5 and 2.5 kWh per cycle.
- Energy-efficient models, such as those with an Energy Star rating, can run on around 1 kWh per cycle or less.
Even if your machine is already economical, an eco-disc can help squeeze out extra savings.
Extra tips to cut dishwasher energy costs
Using an eco-disc is just one part of the puzzle. You can further boost efficiency and save money by:
- Loading smartly – Arrange plates, glasses, and cutlery so the spray arms can rotate freely. A full but well-organised load means fewer cycles.
- Choosing eco mode – This setting uses less water and electricity while still delivering clean results.
- Skipping the pre-rinse – Unless dishes are extremely dirty, modern machines clean better without pre-washing, which wastes water.
- Cleaning the filter – A clogged filter forces your dishwasher to work harder and use more energy.
- Upgrading to a Class A model – If your current machine is old, a newer high-efficiency unit will pay for itself over time.
- Running cycles in off-peak hours – If your electricity plan has cheaper rates during certain times, take advantage of them.
Small changes, big savings
Adding an eco-disc to your dishwasher routine is a low-cost, low-effort way to improve energy efficiency without sacrificing performance. Combine it with a few good habits, and you’ll not only save on your electricity bill but also help reduce your home’s environmental impact — one clean plate at a time.
