How to install the dishwasher with the granite countertop?

I'm going to install the granite countertop in the kitchen, if I mount the dishwasher to the granite directly, I think it may crack very soon due to the vibration from the dishwasher. What's the best way to anchor the dishwasher with the granite countertop properly? thanks.

well granite has a plywood base under it to attach to the cabinets.

But I attached mine to the side cabinets with 2 bolts, you cant see it unless you look in the top right corner of the cabinet.

I think it would be safer to attach it to the side cabinets, but I have to check my dishwasher if I can do that. Thanks a lot!

Yes, most dishwashers have options to screw into the side cabinets. Even if it doesn't, it's easy enough to rig up something to screw into the sides. It just has to hold the dishwasher in place when you open the door, otherwise it'll move forward a bit.

Granite grabbers:

http://cgi.ebay.ca/Granite-Grabbers-Dis ... 563bf3f0f9

They're available for either side or top mount. It's 2 metal brackets with a powerful adhesive which sticks to the granite. The dishwasher can then be bolted to the brackets. I installed this about a month ago (quartz countertop in my case) and it works perfectly in holding the dishwasher in place. I wasn't able to find it locally so I just ordered it from eBay.

I would never ever attempt to install hardware directly into a stone countertop because of the risk of cracking.

This is a interesting product, so I don't have to drill holes on my cabinets. :lol:

If there isn't plywood under tyhe granite already just silcone a piece about 1 1/2 inches wide by 10-12 inches long right where the dishwasher tabs line up let it set-up and your set. The screws are only about 1/2 inch long and are there only to stop the dishwasher from flipping when you open the the door and role out the dish basket.

2 ways to do this. 1) you either PL a piece of 3inX24in plywood/etc to the granite and then screw into that. Very simple and easy to do and the wood wont cost you a thing as you can get it as scrap at HD. Total time 1hr, total cost $7 for the PL...if you have a caulk gun..otherwise another $7 for that.

2) just slide the dishwasher in and wedge the clamps up on the top of the dishwasher so the unit can't slide back out. (only works if you have a lip on your granite..ie not a 1in granite) Cost free.

Silicone and Granite don't mix. It will leak through the granite and leave marks on the upper side. Pl200 or 400. :facepalm: Sorry forgot to mention if it's not sealed on both sides....which the underside MOST likely isn't

Mount the metal tabs directly to the under side of the granite using epoxy.

If you need to release it later, just heat with a heat gun. Silicone can bleed through.

An RTV silicone will not bleed.

OP:

If you use the granite grabbers, make sure to thoroughly clean the underside of the granite. The granite grabbers need a clean surface to adhere properly. Most new dishwashers have side mount brackets to screw to the cabinets. If the stone is 1.25" thick, then I would recommend a filler strip either screwed to the cabinets or siliconed to the stone and clamped in place for a day.
