Can I use shims to level my dishwasher?

Yes, shims can be used to level a dishwasher if the floor is uneven. Place shims under the leveling legs to achieve a level position.

How often should I check the level of my dishwasher?

It's a good idea to check the level of your dishwasher annually or if you notice any issues with water leakage or door closure.

What if my dishwasher is built-in and not level?

For built-in dishwashers, you may need to adjust the leveling legs and ensure the cabinet it is installed in is level. If the cabinet is not level, you may need to address the cabinet installation.
