Apply cyanoacrylate glue liberally around the bolt holes of the latch-action toggle clamp.
Place the toggle clamp so that the side of the clamp with the bolt holes on it is along the right side of the dishwasher. The clamp teeth should be going across the front of the dishwasher door (and be perpendicular to the bolt hole side, because the bolt-hole side is along the right side that is perpendicular to the front side). Press the bolt-hole side firmly against the right side of the dishwasher for five minutes until the glue dries.
Tape over the bolt holes of the latch that are now against the side of the dishwashing until to reinforce the latch's hold on the right side of the unit.
Grab the handle of the latch and move it out and to the left so that the latch's hook can catch on the latch's teeth. Once the hook catches on the teeth, move the handle back to the right to secure the latch.
