Dishwasher Installation questions, answered by experts

Yes, your kitchen flooring should extend under your dishwasher. It is essential for creating a level and stable surface for the appliance and preventing moisture from seeping into the subflooring, which is costly to repair. Working with a kitchen contractor will ensure the new flooring accounts for the height of the dishwasher so it sits under the countertop properly without any glaring gaps.

Any drain in your house requires a water trap to prevent sewer gases from entering the home. Dishwashers don’t have an internal water trap, so they must use an external P trap. The most convenient P trap for the dishwasher is already in the plumbing under your sink.

Maintenance includes regular filter cleaning, checking water connections, and ensuring that the unit operates at optimal efficiency without blockages.

If your dishwasher isn’t draining, some common causes include a clogged drain filter, drain hose, or air gap.

A handy DIYer may be able to figure out how to unclog a dishwasher, but you may need to call in a plumber if you can’t locate and clear the clog yourself.
