Attaching Dishwasher

Cheap on-the-sider updated our 70s kitchen, installing new cabinets and granite countertops. Dishwasher is no longer attached to cabinets/countertop - runs fine but not stable. I need to order parts to attach it to cabinet, but don’t know what to order and where to install it. “Help Desk” on the phone was no help at all and told me to do this. Please help me!

Here is the install sheet for this unit.

They do make a kit that can lock down the rear feet.

OR
Or you could use a couple screws through the frame into the floor.
Put them as far back on the unit as possible.

Also they do make a side mount kit to attach units to the side cabinets.

Unfortunately I have never used one and cannot find the installation sheet which would help you decide if it would do the job.
With luck someone else will jump in with this info.
