Why the COSMO COS-DIS6502 Stands Out in the Market
💰 Breaking Down the Numbers: A Histogram of Product Prices
The COSMO COS-DIS6502 falls within the $625 to $949 price range, which represents the largest segment of built-in dishwashers at 38%. This places it squarely in the most competitive mid-range category, where buyers typically expect a balance of performance, durability, and modern design without paying premium prices.
Lower-priced models between $300 and $624 account for 28% of the market, while higher tiers above $950 drop sharply in representation. This positioning allows the COSMO to offer solid features while remaining far more accessible than premium-built options.
🔇 How Quiet Is This Dishwasher? Noise Level Analysis
With a noise level of 45 dB, the COSMO COS-DIS6502 sits in the most common quiet-performance range of 42 dB to 45 dB, which includes 34% of built-in dishwashers. This confirms it aligns well with mainstream expectations for quiet kitchen operation.
Quieter models below 41 dB are rare at just 4%, while louder units above 50 dB make up a combined 39%. This gives the COSMO a practical advantage by offering low noise without pushing into higher-priced ultra-quiet territory.
⚖️ How It Weighs In: Benchmarking Against Other Models
Weighing 94 pounds, the COSMO COS-DIS6502 falls into the 93.5 lb to 112.9 lb category, representing 26% of built-in dishwashers. This places it slightly above the most common mid-weight range, suggesting a sturdier construction and solid internal components.
Lighter models between 74 lb and 93.4 lb dominate at 37%, while heavier units above 113 lb are far less common. The COSMO’s weight favors stability and durability over easy maneuverability, which is ideal for permanent under-counter installation.
🍽️ Dinnerware Load Test: Ranking Dishwashers by Capacity
The COSMO COS-DIS6502 offers 12 place settings, positioning it within the 11 to 12 place setting category, which accounts for 9% of built-in dishwashers. While this is not the most common capacity, it still meets the needs of medium-sized households.
Larger capacities dominate the market, with 13 to 14 place settings at 28% and 15 to 16 place settings leading at 35%. This means the COSMO prioritizes compact efficiency rather than maximum load volume.
🔄 Cycle Selection: Comparing Wash Options on Different Models
With 4 wash cycles, the COSMO COS-DIS6502 falls into the 3 to 4 wash cycle category, representing just 8% of built-in dishwashers. This places it among simpler, more streamlined models focused on essential cleaning programs.
In contrast, the most common configuration is 6 wash cycles, covering 50% of the market, followed by 5 cycles at 17%. While the COSMO offers fewer cycles, it keeps operation straightforward without overwhelming users with rarely used options.

The top control panel with touch controls and a small LED display keeps the exterior uncluttered while still providing clear cycle status indicators.

✨ Cleaning Performance (4.5/5)
The COSMO COS-DIS6502 delivers dependable cleaning with four well-chosen wash cycles, including Normal, Heavy, Auto, and Express. Its three spray arms provide effective 3-level water coverage, ensuring dishes are cleaned from multiple angles.
The manual, removable multi-filter system helps trap food particles effectively, and for better performance, the entire filter system should be cleaned at least once a week. The Sanitize option heats water up to 158°F (70°C), improving hygiene, while Heated Dry enhances overall results for everyday and heavy loads.

💨 Drying Performance (4.3/5)
This dishwasher uses a heated-dry system with a heating element to efficiently remove moisture. Heat Drying uses a built-in heating element to warm the air inside the dishwasher during the final stage of the cycle.
This heat evaporates moisture from dishes, glasses, and the tub, helping them dry faster and more thoroughly compared to air drying alone. Rinse aid support further improves drying by reducing water spots. While it lacks auto door opening or advanced airflow systems, its heat-based approach remains reliable for daily use.
| Hot Air Drying / Heat Drying | Heated Dry (heating element–based drying) |
| Fresh Air Circulation for Moisture and Odor | Moisture removal via heat evaporation |
| Auto Door Opening for Natural Drying | N/A |
| Rinse aid availability | Yes |
| Built-in Water Softener (For Hard Water) | N/A |
🔕 Noise Level (4.5/5)
Operating at 45 dB, the COSMO COS-DIS6502 runs quietly enough for open kitchens. 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, which is quiet and non-intrusive, offering a peaceful ambiance in your kitchen.
In comparison, the Frigidaire FFCD2413UB runs louder at around 55 dB, while the GE Profile PDT715SYNFS and Kenmore 2214602 match COSMO at 45 dB, making COSMO competitive in its class.
⚡ Energy Efficiency (4.6/5)
The COSMO COS-DIS6502 is ENERGY STAR® certified (Energy Star-certified appliances meet strict energy efficiency standards set by the EPA, using less energy and reducing environmental impact). Running a Normal Wash Cycle with Heated Drying for about 130 minutes uses approximately 1.15 kWh of electricity, similar to running a 1-ton AC on full load for roughly 69 minutes.
Energy consumption for running this dishwasher daily on Normal Wash Cycle with Heated Drying for 30 days equals 34.74 kWh/month. The Delay Start Timer allows scheduling cycles during off-peak hours for added efficiency.
| Energy Star rating | ENERGY STAR® |
| Estimated Energy Consumption / Wattage | 34.7 kWh/month for Daily use of the normal wash cycle with Heated Drying |
| Voltage Required | 120 Volts |
| Delay Start Timer | Yes |
💧 Water Usage (4.5/5)
The COSMO COS-DIS6502 uses 3.0 gallons (11.36 liters) of water per Normal Cycle, striking a good balance between efficiency and cleaning power. In comparison, the Frigidaire FFCD2413UB uses slightly less at 2.9 gallons (11 liters), while the GE Profile PDT715SYNFS consumes more at 3.5 gallons (13.25 liters).
The Kenmore 2214602 varies widely, using between 10.8 to 23.0 liters (2.85 to 6.07 gallons) depending on the cycle, making COSMO more predictable in daily use.
| Water Consumption (Per Cycle) | 3.0 Gallons (11.36 Liters) per wash in Normal Cycle |
🕒 Cycle Time (4.4/5)
Cycle durations are well-balanced for everyday needs. The Normal cycle runs between 105 to 140 minutes, Auto ranges from 105 to 130 minutes, Heavy takes about 140 minutes, and Express finishes quickly in around 60 minutes. This range gives flexibility for both lightly soiled dishes and tougher messes without excessive waiting.

🍽️ Loading Capacity (4.4/5)
With a capacity of 12 place settings (defined further down in this section), the COSMO COS-DIS6502 is suitable for medium-sized households. It features two racks that can hold plates up to 13 inches, and it includes a silverware basket with three separate sections for better organization. While it does not offer a third rack, the layout remains practical for daily dish loads and family meals.
| Number of Place Settings | 12 place settings |

12 – 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.
A 12-place-setting dishwasher is designed to wash 12 dinner plates, 12 dessert plates, 12 soup bowls, 12 cups, 12 glasses, and 12 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 12 dinner plates, 12 dessert plates, 10 soup bowls, 10 cups, 8 glasses, and 12 sets of cutlery comfortably in a 12-place setting dishwasher.
🔒 Safety Features (4.5/5)
Safety is well covered with a Control Lock or Child Lock to prevent accidental operation. 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. It is UL Listed, NSF/ANSI 184 certified, and Energy Star compliant. For safe operation, avoid placing the dishwasher near gas or electric burners, and do not use extension cords or adapter plugs.
| Child Lock – Safety Feature | Control Lock / Child Lock |
| Leak or Overflow Protection – Safety Feature | Overflow protection triggers error codes |
| Non-Slipping Base | Yes |
🛠 Reliability and Durability (4.4/5)
The stainless steel exterior and stainless steel interior tub enhance 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. To keep your warranty valid, use the product only as intended for household use, follow the manual, and avoid misuse, accidents, or neglect, which are not covered under warranty.
