Is Your Dishwasher Supply Too Hot Or Too Cold? Here’s The Answer You’re Looking For!

When it comes to dishwashers, one of the most commonly asked questions is whether the supply water should be hot or cold. This seemingly simple question can have a significant impact on the performance and efficiency of your dishwasher. In this comprehensive guide, we will delve into the intricacies of dishwasher supply water temperature, exploring the pros and cons of both hot and cold supply to help you make an informed decision.

Hot Water Supply

Pros:

• Faster cleaning: Hot water dissolves grease and food particles more effectively, leading to faster and more thorough cleaning.
• Better sanitization: High-temperature water helps kill bacteria and other microorganisms, ensuring sanitary dishes.
• Reduced energy consumption: Since the dishwasher doesn’t have to heat the water itself, it can save energy compared to cold water supply.

Cons:

• Potential damage to dishes: Hot water can damage delicate items such as glassware and certain plastics.
• Increased water heater wear and tear: Heating water to high temperatures puts extra strain on your water heater.
• Higher energy costs: If your water heater is not energy-efficient, heating water to hot temperatures can increase your energy bills.

Cold Water Supply

Pros:

• Gentler on dishes: Cold water is less likely to damage delicate items or cause fading.
• Reduced water heater wear and tear: Cold water supply puts less stress on your water heater, extending its lifespan.
• Lower energy costs: Using cold water eliminates the need for heating, resulting in lower energy consumption.

Cons:

• Slower cleaning: Cold water is less effective at dissolving grease and food particles, leading to longer cleaning times.
• Reduced sanitization: Cold water is not as effective at killing bacteria as hot water, potentially compromising the cleanliness of your dishes.
• Increased energy consumption: The dishwasher will have to use more energy to heat the cold water to the desired cleaning temperature.

Recommended Water Temperature

The ideal water temperature for dishwasher supply depends on several factors, including the type of dishwasher, the type of dishes being washed, and the efficiency of your water heater. However, most manufacturers recommend a water temperature of 120-140°F (49-60°C) for optimal cleaning and sanitization.

How to Determine Your Dishwasher’s Water Supply Temperature

• Check the dishwasher manual: The manufacturer’s instructions will specify the recommended water temperature for your particular model.
• Use a water temperature gauge: Attach a water temperature gauge to the hot water tap and run the water until it reaches a stable temperature.

Factors to Consider When Choosing Water Temperature

• Type of dishes: Delicate dishes such as glassware and fine china should be washed in cold water to avoid damage.
• Soil level: Heavily soiled dishes may require hotter water for effective cleaning.
• Water heater efficiency: If you have an energy-efficient water heater, you may be able to use cold water supply without sacrificing cleaning performance.

Energy Efficiency and Cost Savings

Using cold water supply can save energy and lower water heating costs. However, if your dishwasher does not have a built-in water heater, the energy savings may be offset by the increased energy consumption required to heat the cold water.

Summary: The Balancing Act

The decision of whether to use hot or cold water supply for your dishwasher is not a simple one. It depends on a variety of factors, including the type of dishwasher, the type of dishes you wash, and the efficiency of your water heater. By considering the pros and cons of each option, you can make an informed choice that optimizes the performance and efficiency of your dishwasher.
