As a home appliance expert with extensive knowledge in kitchen technology, I can provide you with a comprehensive answer regarding the water usage of dishwashers.

Dishwashers have evolved significantly over the years, becoming more efficient and environmentally friendly. The amount of water used by a dishwasher can vary depending on several factors, including the model, age, and settings chosen for each cycle.

### Average Water Usage

The average dishwasher typically uses around 6 gallons of water per cycle. This is a considerable improvement compared to hand washing, where it's estimated that up to 15 gallons of water can be used, depending on the efficiency of the individual washing dishes.

### Energy Star-Rated Dishwashers

Dishwashers that are Energy Star-rated are designed to be even more water-efficient. These models generally use about 4 gallons of water per cycle. The Energy Star certification ensures that the dishwasher not only conserves water but also energy, making it a more sustainable choice for the environment.

### Energy Usage

In addition to water conservation, Energy Star-rated dishwashers are also more energy-efficient. The energy use can range from 1.59 kWh per load down to 0.87 kWh per load. This is significantly lower than non-rated models, which can consume more energy.

### Factors Affecting Water Usage

Several factors can affect the water usage of a dishwasher:


1. Model and Age: Newer models are generally more efficient than older ones. Manufacturers are continually improving the technology to reduce water and energy consumption.


2. Cycle Settings: Different cycle settings can alter the amount of water used. For example, a heavy wash cycle will use more water than an eco or quick wash cycle.


3. Load Size: The size of the load can also impact water usage. Overloading a dishwasher can reduce its efficiency and lead to higher water usage.


4. Dishwasher Features: Some dishwashers come with features like sensors that adjust the water and energy usage based on the load's soil level.


5. Maintenance: Proper maintenance, such as cleaning filters regularly, can also help maintain a dishwasher's efficiency and reduce water waste.

### Conclusion

When considering the water usage of a dishwasher, it's essential to look at the overall efficiency of the appliance. While the average dishwasher uses 6 gallons of water per cycle, Energy Star-rated models can significantly reduce this amount to around 4 gallons. Additionally, the energy usage is also a critical factor to consider, especially for those looking to minimize their environmental footprint.

By choosing an Energy Star-rated dishwasher and using it efficiently, you can save water and energy, contributing to a more sustainable household.
