Older dishwashers typically use more water compared to newer, more energy-efficient models. Over the years, dishwasher technology has improved, and newer models are designed to be more water-efficient.
Older dishwashers, especially those manufactured before energy efficiency standards were implemented, may use around 10-15 gallons (37-57 liters) of water per cycle. This higher water usage can lead to increased water bills and have a more significant environmental impact.
On the other hand, modern energy-efficient dishwashers are designed to use much less water. High-efficiency dishwashers, often labeled as Energy Star certified, are required to meet strict guidelines for water consumption. Many newer models use as little as 3-6 gallons (11-23 liters) of water per cycle, making them significantly more water-efficient than their older counterparts.
If you have an older dishwasher and are concerned about water usage, it may be worth considering upgrading to a more water-efficient model. Energy Star-certified dishwashers not only use less water but also consume less energy, which can lead to additional savings on your utility bills in the long run.
