Final answer:
High-temperature dishwashers should reach 150°F to 160°F, while low-temperature dishwashers may operate at 120°F to 140°F. A thermometer should be used to verify the temperature for proper sanitation.
Step-by-step explanation:
The temperature of the wash cycle of high-temperature commercial dishwashers should reach at least 150°F to 160°F for a sanitizing cycle, according to health and safety standards, effectively eliminating bacteria and ensuring cleanliness. On the other hand, low-temperature dishwashers typically use a chemical sanitizing agent and may operate at temperatures around 120°F to 140°F. It's critical to use a thermometer to check that the dishwasher reaches the appropriate temperature to ensure proper sanitation and safety. For high-temperature dishwashers, this is primarily a concern for businesses and restaurants where such standards are strictly regulated for public health. In residential settings, the high temperature might refer to the heated dry option or for specific cycles designed to handle tougher grime. In all cases, it is important to ensure that the dishwasher uses the correct type of detergent formulated for its operating temperature and cycle.
