A comparative noise-level analysis of built-in dishwashers shows that most models fall within the 42 to 53 dB range, while only about 20% operate in the quieter 46 to 49 dB range (see the comparative chart). The KUCHT Professional K7740D built-in dishwasher review highlights a model that sits comfortably in this mid-quiet range, offering a balance between performance and everyday usability. This built-in dishwasher features 6 wash cycles, including Heavy, ECO, and Rapid, as well as a water-efficient normal cycle that uses just 2.5 gallons per wash. While it delivers solid cleaning versatility, its noise level may not match ultra-quiet premium models.

Why the Kucht Professional K7740D Stands Out in the Market
💰 The Price Range Spectrum: Every Bracket at a Glance
The KUCHT Professional K7740D falls into the $700 to $1009 price bracket, which represents about 35% of built-in dishwashers. This places it in the second most common pricing segment, slightly above the largest group priced between $390 and $699, which accounts for 37% of models.
Compared to higher-end categories above $1010, which together make up only about 27% of the market, this model sits comfortably in the mid-range. It offers a balance between affordability and premium-style construction, though buyers looking strictly for budget options may still find cheaper alternatives.
🔇 Is It Whisper-Quiet? A Closer Look at Dishwasher Noise Levels
At 46 dB, the KUCHT Professional K7740D sits in the 46 to 49 dB category, which includes around 20% of built-in dishwashers. The most common noise range is 42 to 45 dB, covering 35% of models, placing this unit just slightly above the quietest mainstream segment.
On the louder side, 28% of dishwashers operate between 50 and 53 dB, and another 11% fall between 54 and 57 dB. This means the KUCHT model still performs quieter than a large portion of competitors, offering a comfortable balance between low noise and overall performance.
⚖️ Weight in Context: Market-Wide Dishwasher Comparison
Weighing around 60 lbs, the KUCHT Professional K7740D falls into the lightest weight category of 45 to 62.7 lbs, which accounts for about 15% of built-in dishwashers. This places it among the more lightweight models in its class.
The most common weight range is 80.7 to 98.4 lbs, covering 38% of the market, followed by 62.8 to 80.6 lbs at 25%. While heavier models may offer a slightly more robust feel, the lighter build of this unit can simplify installation and handling without compromising everyday durability.
🍽️ Place Settings Capacity Compared to Competitors
With an 8 place setting capacity, the KUCHT Professional K7740D falls into the 7 to 8 place setting category, which represents about 17% of built-in dishwashers. This places it among the more compact options designed for smaller households or tighter kitchen spaces.
Larger capacities dominate the market, with 15 to 16 place setting models making up 35% and 13 to 14 place settings accounting for 28%. While it may not match the capacity of full-size units, this model offers a practical solution for apartments or kitchens where space is limited.
🔄 Cycle Count in Context: Benchmarking Against Other Models
Equipped with 6 wash cycles, the KUCHT Professional K7740D fits into the most common category for built-in dishwashers. In fact, models with 6 wash cycles make up about 50% of the market, highlighting this configuration as the industry standard.
Dishwashers with 5 cycles account for around 16%, while those with 7 cycles represent about 10%. More advanced models with 8 or more cycles are less common. This places the KUCHT model in a balanced position, offering enough variety for daily cleaning without unnecessary complexity.

💵 Price and Design (4.2/5)
Priced at around $912, the KUCHT Professional K7740D falls in the mid-range segment of compact built-in dishwashers. Its 18-inch width makes it a practical fit for smaller kitchens, apartments, or secondary prep areas. The stainless steel finish gives it a clean, professional look that blends well with modern cabinetry.
A front-mounted tactile control panel with a digital display keeps operation straightforward, while the cycle status indicator adds everyday convenience. It may lack smart features, but its classic design focuses on reliability and simple usability.

✨ Cleaning Performance (4.4/5)
With 6 wash cycles, including Heavy, Normal, ECO, Glass, Rapid, and Rinse, this dishwasher offers solid versatility for daily kitchen needs. The multi-spray arm system helps distribute water evenly, while options like Hi-Temp keep water at 140 °F (60 °C) to tackle tougher stains.
The Sanitize option raises the temperature to 156 °F (69 °C) to improve hygiene, and the Heated Dry function adds extra convenience. A removable multi-mesh filter system helps trap food particles, and for better performance, the entire system should be cleaned at least once a week.

💨 Drying Performance (4.1/5)
The KUCHT Professional K7740D uses a Heated-Dry system to remove moisture at the end of the cycle. 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 unit also supports rinse aid in a dishwasher, a liquid drying agent that helps improve drying performance and reduce water spots on dishes. While effective, it lacks advanced drying technologies like auto-open or air-refresh systems.
| Hot Air Drying / Heat Drying | Heated Dry |
| Fresh Air Circulation for Moisture and Odor | RINSE option prevents odor |
| Auto Door Opening for Natural Drying | No |
| Rinse aid availability | Yes |
| Built-in Water Softener (For Hard Water) | N/A |
🔕 Noise Level (4.5/5)
Operating at 46 dB, the KUCHT Professional K7740D delivers a pleasantly quiet performance for an 18-inch built-in model. 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 the EdgeStar BIDW1802WH (52 dB) are noticeably louder, while the Bertazzoni DW18PR (49 dB) also produces slightly more background noise.
⚡ Energy Efficiency (4.3/5)
This model is ENERGY STAR certified (ENERGY STAR-certified appliances meet strict energy-efficiency standards set by the EPA, use less energy, and reduce environmental impact), making it a practical choice for long-term savings. A Normal Cycle with a Heated Dry system, running 146 minutes, would use approximately 1.08 kilowatt-hours (kWh) of electricity. To put this into perspective, it’s like running a 1-ton AC at full load for about 65 minutes.
Energy consumption for running this dishwasher daily on Normal Cycle with Heated Dry system for 30 days = 1.08 kWh/day x 30 days = 32.65 kWh/month.
The 24-hour delay start timer adds flexibility. This function lets you schedule a wash cycle to start later. This feature is perfect for running the dishwasher during off-peak energy hours or ensuring clean dishes are ready when you need them.
| Energy Star rating | ENERGY STAR® |
| Estimated Energy Consumption / Wattage | 32.7 kWh/month for Daily use of Normal Cycle with Heated Dry system |
| Voltage Required | 120 V |
| Delay Start Timer | Yes (24 hours) |
💧 Water Usage (4.5/5)
The KUCHT Professional K7740D uses just 2.5 gallons (9.46 liters) per wash in the Normal cycle, making it a water-efficient option for daily use. In comparison, the Avanti DWF18V0W consumes about 3.1 gallons (11.73 liters) per regular cycle, while the EdgeStar BIDW1802WH and Bertazzoni DW18PR both use 2.5 gallons (9.46 liters) per normal wash. This places the KUCHT model among the more efficient units in its category.
| Water Consumption (Per Cycle) | 2.5 gallons (9.46 Liters) per wash in Normal Cycle |
🕒 Cycle Time (4.3/5)
The KUCHT Professional K7740D offers practical cycle durations for different needs. The Heavy cycle runs about 145 minutes, while the Normal cycle ranges from 105 to 135 minutes. The ECO cycle takes around 105 minutes, and the Glass cycle finishes in about 95 minutes. For lighter loads, the Rapid cycle completes in 60 minutes, and the Rinse cycle wraps up in just 20 minutes.

🍽️ Loading Capacity (4.2/5)
This dishwasher supports 8 place settings (defined further down in this section), making it suitable for small families or compact kitchens. It includes two racks that can handle plates up to 11 inches, along with a three-piece silverware basket for organized utensil storage. While it does not include a third rack, the overall layout remains practical for everyday dishwashing.
| Number of Place Settings | 8 Place Settings |
| Dish or Plate Size: A Rack can Accumulate | 11 inches |
| Number of Racks | 2 |
| Special Utensil Holders or Baskets | 3-piece silverware basket |
| Adjustable height of Rack | Adjustable Lower Rack with fold-down tines |
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 one 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 Professional K7740D includes a control lock to prevent accidental operation, which is especially useful in homes with children. It also carries UL safety certification and is CEE Tier I qualified, meeting established electrical and efficiency standards. Additionally, the dishwasher is equipped with a non-slip base to ensure it stays securely in place during operation.
But 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.
| Child Lock – Safety Feature | Control Lock |
| Leak or Overflow Protection – Safety Feature | Leak or overflow indicated via error code |
| Non-Slipping Base | Yes |
🛠 Reliability and Durability (4.4/5)
Built with a stainless steel finish and an interior tub, the KUCHT Professional K7740D under-counter dishwasher 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 is sturdy, but avoid overloading the top surface with heavy items. It also includes a 4-year parts-and-labor warranty and lifetime video chat support. To keep your warranty valid, use the product only as intended, follow the instructions in the manual, and avoid misuse or neglect.
