💨 Drying Performance (4.6/5)
The ZLINE DWMT-304-24 features heated drying, using an internal heating element to actively warm the air inside after washing. Heat drying uses an internal heating element or system to actively warm the air inside the dishwasher after the wash cycle. This added heat speeds up moisture evaporation and leaves dishes dry more quickly, but it consumes more energy compared to other methods.
The Air Refresh function circulates fresh air to eliminate moisture and odor, thereby maintaining a clean and fresh interior. Additionally, the Auto Door Opening function slightly opens the door after the cycle, releasing steam for natural drying. A built-in rinse aid further improves shine and prevents water spots.

| Built-in Water Softener (For Hard Water) | N/A |
🔕 Noise Level (4.8/5)
Operating at just 45 dB, the ZLINE DWMT-304-24 provides an impressively quiet experience. To put the 45 dB dishwasher noise level into perspective, standing about five feet away from the dishwasher would sound similar to the soft hum of a library or light rain falling outside, offering a peaceful ambiance in your kitchen.
In comparison, competitors like the KoolMore KM-DW2445-PR (45 dB) and SHARP SDW6757ES (45 dB) perform similarly, while the LG LDP6810SS (44 dB) is slightly quieter. All fall within the ultra-quiet performance range preferred for open-concept homes.

A Normal Cycle with Heat Drying, running about 130 minutes, uses approximately 1.25 kWh of electricity, roughly equivalent to running a 1-ton air conditioner for about 75 minutes.
Energy consumption for running this dishwasher daily on Normal Cycle with Heat Drying for 30 days = 1.25 kWh/day × 30 days = 37.67 kWh/month. The Delay Start Timer adds flexibility, allowing users to schedule cycles for off-peak hours, maximizing energy savings and convenience.
| Energy Star rating | ENERGY STAR® |
| Estimated Energy Consumption / Wattage | 37.7 kWh/month for the Daily use of the Normal Cycle with Heat Drying |
| Voltage Required | 120 Volts |

💧 Water Usage (4.5/5)
The ZLINE DWMT-304-24 consumes about 3.4 gallons (12.9 liters) of water per Normal wash cycle, which is efficient for a full-size built-in model. In comparison, the KoolMore KM-DW2445-PR and SHARP SDW6757ES each use 3.2 gallons (12.1 liters), while the LG LDP6810SS is slightly more efficient at 2.9 gallons (11 liters) per cycle.
Overall, ZLINE’s water usage strikes a practical balance between thorough cleaning performance and moderate consumption, maintaining both efficiency and wash quality.

16 – Place Setting Dishwasher:

A 16-place setting dishwasher is designed to wash 16 dinner plates, 16 dessert plates, 16 soup bowls, 16 cups, 16 glasses, and 16 sets of cutlery in one cycle.
In reality, the exact combination can vary due to item sizes and shapes. For example, you can comfortably fit 16 dinner plates, 16 dessert plates, 14 soup bowls, 14 cups, 12 glasses, and 16 sets of cutlery in a 16-place setting dishwasher.

🛠 Reliability and Durability (4.8/5)
Built with 304-grade stainless steel inside and out, the ZLINE DWMT-304-24 is engineered for long-term durability. Stainless steel is a strong, corrosion-resistant material prized for its durability, sleek appearance, and ability to withstand high temperatures and exposure to moisture without rusting or degrading. The dishwasher is sturdy, but avoid overloading the top surface with heavy items.
A 1-year parts and body warranty supports user confidence. To keep your warranty valid, use the product only as intended (not for commercial or non-household use), follow the instruction manual, and avoid misuse, mishandling, accidents, neglect, or abuse, as these are not covered.
