What is the difference between hot feed and cold feed for dishwashers?
The primary difference between hot feed and cold feed lies in the temperature of the water being supplied to the dishwasher. A hot feed provides hot water directly from the home’s hot water system, typically around 120°F (49°C), which is essential for effective cleaning and sanitization. On the other hand, a cold feed supplies cold water, which the dishwasher heats internally. This process may take longer and could potentially decrease washing efficiency.
Hot feed systems generally contribute to shorter cycles and better cleaning performance as the optimal temperature for detergent activation is achieved right away. In contrast, cold feed systems may require additional energy to heat the water, which can lead to longer wash times and potentially less hygienic results if the water does not reach the required temperature during the cycle.
Does my dishwasher need hot water to operate effectively?
While most dishwashers are designed to function with either hot or cold water, using hot water typically yields better results. Hot water assists in breaking down food particles and dissolving grease more efficiently than cold water. Moreover, many detergents require a specific temperature to activate properly, which is more easily achieved with a hot water supply.
In cases where the dishwasher relies on cold feed, it will need to heat the water to the appropriate temperature during the cycle. This could lead to increased energy consumption and longer cycle times, which may not be ideal for households with high dishwashing demands. Therefore, while it’s not strictly necessary for effective operation, a hot water supply is recommended for optimal cleaning.
