It defines where Kucht K7740D falls compared to other builtin countertop dishwashers in the market.

The price analysis chart shows that the $625 to $949 range is the most crowded segment in the built-in dishwasher market, covering 39 percent of models. The Kucht K7740D, priced at $912, sits firmly within this dominant bracket, placing it among the most commonly priced built-in options rather than niche luxury models.

Lower-priced dishwashers between $300 and $624 still represent 28 percent of the market, while higher tiers above $950 quickly thin out. This positioning suggests the K7740D leans premium for an 18-inch model, but remains within a competitive and widely accepted price range.

With a noise rating of 46 dB, the Kucht K7740D falls into the 46 dB to 49 dB category, which represents 23 percent of built-in dishwashers. This places it quieter than the largest group operating at 42 dB to 45 dB (32 percent), while still maintaining strong cleaning performance.

Louder models in the 50 dB to 53 dB range account for 29 percent, and noise levels above 54 dB become far less common. Overall, the K7740D holds a clear advantage for users who want a noticeably quiet dishwasher without paying ultra-premium prices.

Weighing 60 lbs, the Kucht K7740D falls into the 54.5 lb to 73.9 lb weight category, which includes 22 percent of built-in dishwashers. This places it lighter than the most common bracket of 74 lb to 93.4 lb, which dominates the market at 36 percent.

Heavier models above 93.5 lb typically indicate larger, full-size dishwashers with higher capacity. The K7740D’s lighter build reflects its compact 18-inch design, making installation easier while still offering solid stability once installed.

💵 Price and Design (4.3/5)

Priced at $912, the Kucht K7740D positions itself in the premium segment of 18-inch built-in dishwashers. Its stainless steel finish gives it a clean, professional look that fits well in modern kitchens, while the front control panel with a digital display keeps operation straightforward and intuitive.

 Measuring 32 inches high, 18 inches wide, and 23 inches deep, it is well-suited for compact spaces without feeling undersized. The solid door design and standard built-in installation make it a polished, long-term kitchen upgrade, though the premium pricing may feel high for budget-focused buyers.

✨ Cleaning Performance (4.5/5)

The Kucht K7740D delivers strong everyday cleaning with six wash cycles, including Heavy, Normal, ECO, Glass, Rapid, and Rinse, covering most household needs. It features a dual-spray arm system and a multi-spray arm cleaning design that ensures thorough water coverage.

 Options like Hi-Temp Wash, which maintains water at 140 °F (60 °C), and Sanitize, reaching 156 °F (69 °C), help tackle stubborn grease and hygiene concerns. The removable, multi-mesh filter system effectively traps food debris; for better performance, the entire system should be cleaned at least once a week.

💨 Drying Performance (4.2/5)

Drying performance is handled through Heated Dry, supported by rinse aid compatibility for improved results. 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 drier more quickly, but it consumes more energy than other methods.

 The inclusion of rinse aid further enhances drying by reducing water spots and streaks. While there is no automatic door opening or fresh-air circulation, drying remains reliable for daily loads when Heated Dry is enabled.

🔕 Noise Level (4.6/5)

Operating at just 46 dB, the Kucht K7740D is impressively quiet for a built-in dishwasher. To put the 46 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, which is quiet and non-intrusive, offering a peaceful ambiance in your kitchen.

 In comparison, competitors like the Avanti DWF18V0W (53 dB) and EdgeStar BIDW1802BL (52 dB) are noticeably louder, while even the Bertazzoni DW18PR (49 dB) does not match the same level of quiet operation.

⚡ Energy Efficiency (4.4/5)

The Kucht K7740D is ENERGY STAR® certified (ENERGY STAR-certified appliances meet strict energy-efficiency standards set by the EPA, use less energy, and reduce environmental impact). It runs on 120 V power and is designed to balance performance with efficiency.

 A Medium Wash Cycle with Heat Dry System, running 130 minutes, would use approximately 1.22 kilowatt-hours (kWh) of electricity, similar to running a 1-ton AC on full load for about 73 minutes. Running this dishwasher daily for 30 days consumes 36.6 kWh per month. The Delay Start Timer adds flexibility by allowing off-peak energy usage.

Energy Star ratingENERGY STAR®
Estimated Energy Consumption / Wattage234 kwh
Voltage Required120 V
Delay Start TimerYes

💧 Water Usage (4.6/5)

The Kucht K7740D is highly water efficient, using just 2.5 gallons (9.5 liters) of water per wash on the Normal cycle. This is noticeably lower than competitors like the Avanti DWF18V0W, which uses 3.1 gallons (11.7 liters), the EdgeStar BIDW1802BL at 3.10 gallons (11.73 liters), and the Bertazzoni DW18PR, which consumes 3.2 gallons (12.1 liters) per wash. This lower water usage makes the Kucht K7740D a wise choice for households aiming to reduce water consumption without sacrificing cleaning performance.

Water Consumption (Per Cycle)2.5 gallons (Normal cycle)

🕒 Cycle Time (4.4/5)

The Kucht K7740D offers a practical range of cycle durations to suit different cleaning needs. The Heavy cycle lasts about 145 minutes, while the Normal cycle ranges from 105 to 135 minutes.

The ECO cycle completes in approximately 105 minutes, and the Glass cycle takes around 95 minutes. For quicker needs, the Rapid cycle finishes in just 60 minutes, while the Rinse cycle runs for a short 20 minutes. For a deeper dive into specific wash cycles, please refer to our section: “Specialized Wash Cycles.”

🍽️ Loading Capacity (4.2/5)

Designed for compact kitchens, the Kucht K7740D offers 8 Place Settings (defined further down in this section), making it suitable for small families or apartments. It comfortably handles plates up to 11 inches and includes two racks for organized loading. A three-piece silverware basket keeps utensils neatly separated, making cleaning easier. While it lacks a third rack, the layout remains practical and efficient for everyday dishwashing.

8 – Place Setting Dishwasher:

A place setting refers to the dishes and utensils needed for one person’s meal. In dishwashers, it indicates the number of such sets the appliance can handle in one cycle.

An 8-place-setting dishwasher is designed to wash 8 dinner plates, 8 dessert plates, 8 soup bowls, 8 cups, 8 glasses, and 8 sets of cutlery in a single cycle.

In reality, the exact combination can vary due to item sizes and shapes. For example, you might fit 8 dinner plates, 8 dessert plates, 6 soup bowls, 6 cups, 4 glasses, and 8 sets of cutlery comfortably in an 8-place setting dishwasher.

🔒 Safety Features (4.3/5)

The Kucht K7740D includes essential safety features designed for secure daily use. A Control Lock helps prevent accidental operation, especially in homes with children.

 The dishwasher also features a non-slip base, ensuring it stays securely in place during operation. However, do not place or use the machine on an unstable or uneven platform. For safe operation, avoid placing the dishwasher near gas or electric burners. Also, do not use extension cords or adapter plugs.

Non-Slipping BaseYes

🛠 Reliability and Durability (4.6/5)

Built with a stainless steel finish and stainless steel interior tub, the Kucht K7740D is designed 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 feels sturdy, but avoid overloading the top surface with heavy items. It is backed by a 4-year parts-and-labor warranty and lifetime video chat support from a KUCHT specialist. To keep your warranty valid, use the product only as intended and follow the instruction manual carefully.
