Use the installation drawing to check the 6-inch corner clearance; it is not the full distance needed in front of an open door.
Rear connections route through the adjoining cabinet. The installation instructions show a 2.5 × 3.5-inch service opening; confirm the exact location in the drawing.
The spec sheet and installation guide give different minimum cavity dimensions. The automatic shortlist uses the stricter spec-sheet dimensions; smaller openings require installer review.
The spec drawing gives 23 5/8 inches without decor strips. That conditional configuration is not treated as a standard 24-inch installation.
No explicit maximum cavity height was found in the reviewed installation drawing. The 34 7/16-inch body-height maximum is not substituted for it.

Installation is not guaranteed. Confirm the full manufacturer instructions and your site conditions with the installer.

Start with the differences that matter to you.

The published specifications give you specific differences to weigh. They do not establish cleaning or drying performance in your home. Choose the features you care about, then confirm the opening, delivery and installation requirements.
