Dishwasher efficiency

Dishwasher technology has improved spectacularly over the last decade. New qualified models include several innovations that reduce energy, water and detergent consumption. Just choose a qualified and energy efficient model, properly sized.

Around 80 percent of the energy used by a dishwasher goes to heat water. So, when buying a dishwasher prefer an energy efficient one, wit a low water consumption.

Do not forget: saving energy prevents global warming and pollution. Choosing a qualified dishwasher model will not represent any sacrifice in terms of quality or price and promotes cleaner air…

Size and type of dishwashers

If you have to operate a small compact model frequently, you have to use more energy than you would with a standard larger model.

Choose an energy efficient model

Choosing a dishwasher with multiple wash cycle selections is important for energy savings… To evaluate this and other features of dishwashers, take into account the Yellow EnergyGuide label (in USA and Canada) or the Eco-label (in Europe) or the Energy Rating Label (in Australia…).

Prices, manufacturers and warranties

Dishwasher prices vary a lot. There are $200 models and state-of-the-art $2,000 models. Typically, the same manufacturer has different models with different prices and warranties, but the price is not always a synonym of quality.

Energy savings & dishwashers

For energy savings, follow these tips:

- Since most of the energy used by a dishwasher is to heat water, avoid - as much as possible - running partial loads. Since we can’t decrease the water used per dishwasher cycle, the better way to get high energy savings is not running it unnecessarily.

- Options like the heat-dry, rinse-hold and pre-rinse are highly energy demanding. Avoid using them unnecessarily.

- If your dishes aren’t too dirt, use an energy-saving wash cycle; use short cycles options as much as possible. The dirtiest dishes demand longer cycles, but short cycles use less energy and are sufficient in many cases.

- Do not use rinse hold and other demanding energy options for just a few dirty dishes. Use the air-dry option dishwasher setting instead (you will get energy savings from 15 to 50%). If your dishwasher hasn't an air-dry option, you may turn the dishwasher off and open its door after the last rinse.
