ZLINE DWMTZ-BS-24-KCB Dishwasher Review

The DWMTZ-BS-24-KCB is a 24-inch built-in, tall-tub dishwasher from the ZLINE Monument Series, Autograph Edition, in black stainless steel with a champagne bronze Helix handle. The KCB in the code marks that knurled, textured handle, which resists fingerprints; the same dishwasher is offered with a smooth handle under a different code. If you searched this exact model number, that handle is the difference you were checking.

The front face stays clean because the touch controls sit on the top edge of the door. Inside, a stainless steel tub holds three racks, including a third rack for cutlery and small items, and a cutlery basket comes in the box. A floor-projected timer shines the remaining time onto the floor, and an LED light illuminates the interior when the door is open.

The finish is the headline here, not an afterthought. This is a machine built to sit at the center of a custom luxury kitchen, and the black stainless panel with bronze hardware is what the design is organized around.

The noise rating is 44 dBA. Drying pairs a heated dry cycle with Auto Door Open: at the end of the cycle the door releases and swings open so steam escapes and fresh air moves through the tub. That combination targets plastics and awkward dishware that usually come out wet.

Capacity is 16 place settings across three racks, with collapsible tines for odd loads and two wine glass holders. High-pressure bottle wash jets direct water into bottles and tall narrow items, and the tall tub takes plates up to about 13⅞ inches while the upper rack clears items up to about 13 inches tall, which matters for stockpots and tall glasses.

Six wash cycles include a Delicate cycle and a short 20-minute Rinse for a quick refresh between full loads. Sanitize and Hi-Temp options are there, along with a delay start. The machine is ENERGY STAR certified at 240 kWh/year and about 3.2 gallons per cycle, so it is efficient to run.

The look carries its own weight: fingerprint-resistant black stainless, the knurled bronze handle, the floor timer and the interior light all read as premium details. Those features, plus the quiet rating and the auto-open drying, are what the design and the build deliver.

The electrical connection is the biggest practical limit. The dishwasher is hardwired only: 120V, 60Hz, 8.4A on a dedicated 15-amp circuit, with a junction box included. There is no cord and plug. If the old dishwasher in that opening plugged into a receptacle, plan on an electrician or a hardwire-capable installer.

The box includes a cutlery basket.

Auto Door Open means the door stands open at the end of every cycle. In a tight galley, or with toddlers or pets around, that open door is a daily consideration to plan around rather than a defect.

The warranty runs one year on parts and labor. At about 110 pounds, the machine's weight is worth planning for before installation. The feature set stays focused on washing, drying and looks: there is no steam function, no Wi-Fi or app control and no leak detection.

The Monument Series dishwasher also comes as the DWMTZ-30424-KCB, finished in stainless steel instead of black stainless steel. Both versions are 24-inch built-in tall-tub models with the champagne bronze Helix handle, and their dimensions differ by a fraction of an inch: 25.18 by 23.88 by 34 inches for the stainless steel model against 25.19 by 23.84 by 34 inches for the black stainless steel one. Choose the finish that matches the rest of your kitchen, since the two share the same handle and footprint.

The opening has to be a true 24 inches wide, 25 inches deep and 34 inches high. The unit itself is 23.84 inches wide, so it slides into a standard opening, but a tight or out-of-square cutout is the usual reason a dishwasher will not go in.

Check the electrical as well. The machine needs a dedicated 15-amp circuit and a hardwired connection, and the junction box is in the unit.

• The machine weighs about 110 pounds.
