Step 4 · Prepare New Dishwasher Fittings
Prepare the new dishwasher for installation before sliding it into place. Carefully tip the new unit onto its back on a piece of cardboard to protect it. Locate the water inlet valve. Wrap the male threads of a new 90-degree brass elbow fitting with 3-4 layers of Teflon tape in a clockwise direction. Screw this fitting into the dishwasher's plastic inlet valve, hand-tightening first and then giving it a gentle quarter-turn with a wrench. Do not over-tighten, as this can crack the plastic housing. Orient the elbow to point towards the rear of the dishwasher, where the water line will connect.
