To secure a dishwasher properly, it is typically anchored to the underside of the countertop or to the sides of the cabinet using mounting brackets and screws. Here are the main methods:
- Most dishwashers have metal mounting brackets on the top that fit into slots on the dishwasher. These brackets get screwed into the underside of the countertop with short screws that do not go through the countertop completely. This prevents the dishwasher from tipping forward when the door is open.
- If the countertop is made of granite, quartz, or other hard materials that cannot be drilled, a strip of plywood can be attached to the underside first, then the brackets are screwed into the plywood.
- Some dishwashers allow side mounting brackets that attach to the side of the dishwasher and are screwed into the cabinet sides. The side brackets often have plastic caps that cover screw holes.
- When mounting brackets to the countertop or cabinet sides, use appropriate small screws (around 1/2 inch or 1 inch fine-threaded screws) to avoid damaging the cabinets or countertop. Ensure the dishwasher is level before fully tightening screws.
- To prevent brackets from loosening, bend the tabs on the brackets to lock them in place. Screws may need to be replaced if the holes are stripped.
- It is important that the dishwasher is stable, flush with the cabinet or countertop, and doesn’t tilt forward when the door is open.
This securing process prevents the dishwasher from moving, tipping forward, or causing damage during operation or when the door is loaded or unloaded.
