The Cosmo COS-DIS6502 is a good buy for a specific shopper: someone who wants a 24-inch built-in with a stainless steel tub inside and out, quiet 51 dB operation, hidden top touch controls and a fingerprint-resistant finish, and who will run Heated Dry with rinse aid. It is not a universal pick. A stainless tub, 51 dB operation and a sanitize rinse are the features that justify this model, and they are the reasons it holds its place among 24-inch built-ins.
What the Cosmo COS-DIS6502 does well
The Cosmo COS-DIS6502 earns its place for quiet running, solid cleaning and a build that looks more expensive than the machine's position in the market suggests.
Quiet operation
The noise level is 51 dB. Buyers on Amazon single out how quiet it is more often than any other point.
Cleaning and cycles
Four cycles cover the everyday jobs: Heavy, Normal, Rapid and Sensor Wash. A Smart Wash system detects whether the load is partial or full and picks the correct cycle for it, so you do not have to guess at the panel. Buyers on Amazon report strong cleaning results, and cleaning performance is the second topic they mention most.
Build and finish
The tub and door are high-grade stainless steel, inside and out, and the exterior carries a fingerprint-resistant stainless finish that wipes clean without a polish. Controls are fully integrated and touch-enabled, hidden away when the door is closed, so the front reads as a clean stainless panel.
Rack flexibility and drying
The upper rack adjusts by 2 inches, which buys room for taller items such as stock pots and stemware. A Heated Dry function handles the drying step.
Certifications and looks
The dishwasher is ENERGY STAR certified and UL Listed. The tall-tub design with hidden controls gives a kitchen a built-in look that reads as more expensive.
Where the Cosmo COS-DIS6502 falls short
None of these limits is a dealbreaker on its own, but each one is worth knowing before you order.
No smart features
There is no Wi-Fi and no app control. The dishwasher runs from its own touch panel and nothing else.
A one-year warranty
Coverage is a 1-year limited parts and labor warranty, which is shorter than some buyers expect for a major appliance.
Buyers are divided on build and value
Buyers on Amazon are split on build quality and on whether the machine is worth the money. Some find it well built and a fair deal; others report poor construction and disappointment. That division is part of an honest verdict: the quiet running and the cleaning draw praise, while the sense of solidity does not convince everyone.

See on AmazonThe specifications that actually matter
These are the figures to check against your kitchen before you buy, and the ones that shape how the machine runs day to day.
| Spec | Figure | Why it matters |
|---|---|---|
| Dimensions | 23.75 in wide, 22.25 in deep, 33.75 in high | The width fits a standard 24-inch cabinet opening; the depth and height decide whether the door clears your countertop and whether the tub sits flush. |
| Weight | 94 lb | Plan on two people to move it into place. |
| Form factor | Built-in, 24-inch class, tall tub | A tall tub gives more vertical room for plates and pots than a short tub. |
| Noise | 51 dB | Quiet enough for an open-plan kitchen or a room next to the living area. |
| Electrical | 120 V; requires a 3-prong plug (not included) | You need the plug on hand before the installer arrives. |
| Water connection | 3/8-inch pipe fitting, sold separately | Same story: buy the fitting ahead of installation day. |
| Cycles | Heavy, Normal, Rapid, Sensor Wash | Four cycles cover baked-on pots, everyday loads, a quick refresh and soil-sensing washes. |
| Smart Wash | Auto-detects partial or full loads | The machine picks the cycle, so you do not have to. |
| Options | Heated Dry, Advanced Sanitize Technology | Drying and a sanitize rinse for bottles and boards. |
| Racks | Three racks; upper rack adjusts 2 inches | Flexibility for tall items, with a clearance check worth doing first. |
| Materials and finish | Stainless steel tub and door; fingerprint-resistant stainless finish | |
| Controls | Fully integrated, touch-enabled, hidden when the door is closed | A clean front panel and controls out of reach of small hands. |
| Certifications | ENERGY STAR, UL Listed | Efficiency and a recognized safety listing. |
| In the box | Installation kit, install and user guides | The kit and guides are there; the plug and fitting are not. |
| Warranty | 1 year limited parts and labor | Shorter coverage than some buyers expect. |
Measure before you buy
Confirm your cabinet opening's width, depth and height against the 23.75-inch width, 22.25-inch depth and 33.75-inch height before ordering. Then confirm you have the 3-prong plug and the 3/8-inch fitting on hand, since the box holds only the installation kit and the install and user guides.
The Cosmo COS-DIS6502 suits a buyer who wants a quiet, stainless-tub 24-inch built-in with a sanitize option and a clean hidden-control front, and who will run Heated Dry with rinse aid. Its 51 dB rating, stainless tub and sanitize rinse are its strongest features. Skip it if you need smart features, or if your cabinet depth is tight. Before ordering, measure your cabinet opening against the 23.75-inch width, 22.25-inch depth and 33.75-inch height, and confirm you have the 3-prong plug and the 3/8-inch fitting on hand.
Frequently asked questions
Fit and the two parts that do not ship in the box are what most buyers want settled before they order a built-in dishwasher.
Is the Cosmo COS-DIS6502 a freestanding or built-in dishwasher?
The Cosmo COS-DIS6502 is a built-in, slide-in tall-tub dishwasher made to sit in a 24-inch cabinet opening, even though its product listing describes it as freestanding. Plan for a cabinet opening rather than a standalone placement.
Can the Cosmo COS-DIS6502 fit tall pots and stemware?
Yes. The upper rack on the Cosmo COS-DIS6502 adjusts by 2 inches, and the machine has three racks in total, so you can lower the top rack when a load needs more vertical clearance.
What drying option does the Cosmo COS-DIS6502 offer?
Heated Dry is the drying option on the Cosmo COS-DIS6502.
What do buyers on Amazon say about the Cosmo COS-DIS6502 build quality and value?
Buyers on Amazon are divided on build quality and value: some find it well built and a fair deal, while others report poor construction and disappointment. You can weigh that split against the quiet running and cleaning that buyers praise.
Can the Cosmo COS-DIS6502 be controlled from a phone?
No. Every cycle on the Cosmo COS-DIS6502 is started from the hidden touch panel on the door, and the four cycles are Heavy, Normal, Rapid and Sensor Wash.
