How to Secure a Dishwasher to a Granite Countertop
Updated: Sep 29, 2018
When a dishwasher is installed, it must be secured in place to prevent it from sliding around or shifting out of position. Now, that's not a problem with wood and plastic laminate counters: drive two screws through mounting holes or tabs and into the underside of the counter.
But what happens if your countertop is made of granite, quartz, marble or solid-surfacing? You can't simply drive screws into these hard materials. Fortunately dishwasher manufacturers have made accommodations for just such instances.
If your dishwasher is new or even relatively new--meaning built within the last 10 years or so--it likely came with two metal mounting tabs. The tabs have small hooks on one end and screw-mounting holes on the other. At the top of the dishwasher are two slots that accept the hook-end of the mounting tabs. Those top-position slots are used for screwing to wooden or plastic laminate counters. Obviously they're not useful for granite counters.
However, if you look closely along the right and left sides of the dishwasher you'll find another pair of slots. Slip the hook-end of the tabs into the side slots, as shown above. Next, use needlenose pliers to bend the largest of the hooks outward, as shown below right, to lock the tab in place. Repeat to install the second tab on the opposite side of the dishwasher.
Now drive a small screw through each tab and into the edge of the cabinet stile, as shown below. Before tightening the screws, be sure the dishwasher is parallel with the front edge of the counter. And if one of the tabs protrudes past the front of the cabinet, trim it to length with aviation snips.
