Securing a Dishwasher to a Granite Countertop
I'm looking for guidance on securing a dishwasher properly to a granite countertop. There is about a 3/4" gap between my counter and the dishwasher mounting brackets. I've read in various places on the internet that you can epoxy a strip of wood to the counter then secure the dishwasher to this strip. This sounds doable for me but I'm not sure of a few things:

1. Is there a special type of wood and thickness that I should be using? The mounting screws that came with my dishwasher are 5/8".

2. What type or name brand epoxy is best for this application? If there is something I can get from HD or Lowe's that would be great.

3. Once epoxied, should I use clamps to hold the wood strip to the counter overnight before screwing into it?

The only other option provided by the manufacturer (Frigidaire) is to order a side mount kit that will up to a week to get and may be more costly than the wood strip option.

If someone can address my questions and/or give more insight into this I'd appreciate it.

Thanks in advance.

Issue is that any wood you would glue to underside of the countertop will likely prevent you from installing the dishwasher without a gap of say 1/2 to 3/4" (approx thickness of wood strip you would glue to put screws into). That might look ugly when done.
My GE dishwasher had holes in side frame that could be screwed into the styles of the adjoining cabinets in this situation.
Me, I'd wait for the side mounting kit so it will look good; sometimes beauty comes at a price in time and money. It will be there quite a while and you might as well spend the $s and wait the time to do it right IMO.

Why is there a 3/4" gap? Did you run the flooring under the DW?
Most granite companies will drill out holes in the granite and install wood plugs for the DW install. But I agree with bob22, at this point do a side install. Waiting a week for the right parts is better than a lousy install.

Isn't the DW on adjustable legs? I've done this in a couple of houses: 1) raise the adjustable legs to get the brackets close to the granite; 2) using a minimal amt of construction adhesive, glued thin (1/4-3/8") wood strip about 3/4" wide; used small pan-head screws to hold it in. Can't see it from the front at all unless the DW is open and you get down on your knees. By adjusting the DW legs, the screws are not holding the weight of the DW up, they are only keeping it from tipping. Don't remember where I read about this method, but I didn't invent it. Worked fine for me.

You can "dry fit" and verify how it looks.

That said, I would have tried the side mount had I known... seems cleaner & more secure. Now I know.

Any/all new dishwasher can be had with side mounts to mount it to the side of the cabinets and not the countertop.

Ditto on the side mount kits. Most are just a plastic stip on each side that fastens to the dishwasher and gets screwed to the side of the cabinet style. I have also fastened d/w's to granite tops that had the two metal straps on top using GE silicone seal. Wipe off the bottom of the granite with a slightly damp cloth to get rid of any dust. Adjust the feet on the dw so it is level and the gap is what you want on top. Bend the straps to they push up against the bottom of the granite. Pull straps away from the granite without bending them, apply a nice blop of GE ss to the granite and let each strap settle into it. apply a little more to the bottom side of the strap to completely enclose it. Shut the door and leave it alone for 24 hours. My own was done this way in 2003 and is still fine.

Adjust the dishwasher legs so the unit is close to the counter. Move the screw tabs to the side and attach the dishwasher to the cabinets.
Look at the instruction manual for the specifics.
