Kitchen Large Electric Appliances - Securing dishwasher to granite countertop

I have a GE Eterna dishwasher with two brackets on top that typically get screwed into the countertop. My problem is, contractor won't risk screwing into granite in case it cracks and wants granite installer to drill hole. I had problems with granite guy and don't want to use him anymore. Can I use liquid nails then clamp it in place 'til it dries? Will that be strong enough? Is that product safe to use on unfinished bottom of granite surface?

I agree totally with your contractor, drilling into granite is a specialty item -
In any case, I don't think granite would hold screws for this purpose.
Most dishwashers move very little. If you glue it with liquid nails etc, it's going to be a #%*@# to get out for servicing. I think your best bet is to use some kind of foam like that used to line pipes. - Stuff it in the gap between washer top and the countertop. :cool:

Drilling into the granite is not the way to go. Liquid nail will not harm the underside of the granite. You could liquid nail the brackets to the stone (if needing to remove later a putty knife will separate the adhesive from the stone).
A better option would be to glue with epoxy (liquid nail if you must) a piece of wood to the stone along the top of the DW opening and either stain or trim to match the cabinetry and screw to that. You may need to lower the DW to allow enough spacing.

Sargo,
- that option of gluing a wood section and staining to match sound great :) You must have encountered this problem before, -way to go. :cool:

This is actually a very common issue. Often this can be avoided by using a "laminated" or 4cm edge in place of a 3cm slab. This gives you the ability to secure wood to the stone and have the drop edge cover it. It may cost a little more, and unfortunatley a lot of people do not get informed about it until after the fact. ;-{
