Several factors can influence the amount of hot water your dishwasher uses:

1. Dishwasher Model

Different models have varying specifications for water usage. High-efficiency models are designed to use less water.

2. Wash Cycle Selection

Choosing a heavy-duty cycle will generally use more water compared to a quick wash cycle.

3. Load Size

A fully loaded dishwasher is more efficient and uses less water per dish than a partially loaded one.

4. Water Temperature Settings

Most dishwashers require water to be heated to at least 120°F for optimal cleaning, affecting overall hot water consumption.
