Heated Dry: How It Works
Heated dishwasher drying utilizes an electric heating element, typically located at the bottom. After the final rinse cycle, the heating element warms up, increasing the temperature inside the dishwasher. This heat causes the water droplets on the dishes to evaporate, turning into steam, which then gets vented out. The residual heat from the hot water used in the final rinse assists this process, making the dishes dry faster and more thoroughly.
Advantages of Heated Dry
- Speed and Efficiency: Heated drying is much faster than air drying, with intense heat that quickly evaporates water, allowing dishes to be ready for use immediately after the cycle.
- Better Results on Plastics: Effectively dries plastic dishes and containers by quickly evaporating water from surfaces, eliminating the need for towel drying.
- Hygienic Drying: The high temperatures kill bacteria on dishes, providing additional sanitation.
- Convenience: Eliminates the need to wipe down dishes or leave them to air dry, saving time and effort.
Disadvantages of Heated Dry
- Higher Energy Consumption: Heated drying increases electricity usage due to the energy required to operate the heating element, leading to higher utility bills.
- Potential Damage to Delicate Items: The high heat can damage delicate items such as fine china or crystal, possibly causing them to crack or deteriorate over time.
- Increased Wear and Tear: Regular use of heated dry can lead to more frequent repairs and potentially shorten the lifespan of the dishwasher’s components.
Air Dry: How It Works
Air drying in dishwashers relies on natural evaporation to remove moisture from the dishes. After the final rinse cycle, the dishwasher automatically stops heating the water. Instead of using a heating element, it allows the dishes to cool down gradually. The residual heat from the hot water used in the rinse cycle, combined with the ambient air inside the dishwasher, causes the water droplets on the dishes to evaporate. This method uses the principle of condensation drying, where cooler stainless steel walls attract moisture from the warmer dishes, leading the water to drip down to the bottom and away from the dishes.
Advantages of Air Dry
- Energy Efficiency: Air drying consumes significantly less electricity than heated drying, as it does not require a heating element, leading to lower energy bills and a reduced carbon footprint.
- Gentle on Dishware: The absence of intense heat makes air drying gentler on all types of dishware, including delicate items such as fine china, glassware, and plastic, reducing the risk of damage.
- Environmentally Friendly: By reducing energy consumption, air drying is more eco-friendly, helping to conserve energy resources and lower greenhouse gas emissions.
- Cost-Effective: Air drying does not use additional energy, making it more cost-effective by saving on operational costs and reducing potential repair expenses due to less wear and tear on the heating element.
Disadvantages of Air Dry
- Longer Drying Time: Air drying takes longer to completely dry dishes than heated drying, often requiring additional time either in the dishwasher or on the counter.
- Less Effective on Plastics: Plastic items tend to retain water droplets, possibly requiring manual towel drying after the cycle.
- Risk of Water Spots: Natural evaporation can leave water spots or streaks on dishes, especially in areas with hard water high in minerals.
- Potential for Mold and Mildew: If the dishwasher isn’t properly vented or the door remains closed post-cycle, trapped moisture can promote mold and mildew growth.

Impact on Dishware
Heated Dry and its Effect on Different Materials
Heated drying uses high temperatures to evaporate moisture from dishes, which can have varying effects on different materials:
| Material | Heated Dry Impact | Air Dry Impact |
|---|---|---|
| Glass/Ceramics | Generally handles well; risk of thermal shock causing breaks. | Less risk of thermal shock; may retain water spots. |
| Plastic | Can warp, melt, or become brittle; higher wear and tear. | Gentler; no high heat involved, but might need towel drying. |
| Metal | Most can withstand; non-stainless metals may discolor. | Does well; less risk of discoloration but may form water spots. |
| Wood | Should not be used; can crack or warp. | Less harsh but still risky for warping or cracking. |
Cost Considerations
Operational Costs of Heated Dry
Heated drying cycles consume more energy, leading to higher operational costs. On average, the heated dry setting can increase your dishwasher’s energy usage by 15-50%, depending on the model and cycle length. This added energy consumption translates to higher electricity bills over time. Additionally, the frequent use of the heating element can lead to increased wear and tear on the appliance, potentially resulting in more maintenance and repair costs.
Operational Costs of Air Dry
Air drying is significantly more cost-effective as operating a heating element does not require additional energy. By relying on residual heat and natural air circulation, air drying reduces the dishwasher’s overall energy consumption, lowering electricity bills. The savings on energy costs can add up over time, making air drying a more economical choice. The reduced wear and tear on the dishwasher’s components can also lead to lower maintenance costs.
