Dishwasher Installation questions, answered by experts

DIY installation or repair is possible with the right skills and tools, but if not done correctly, it can often lead to water leaks or improper connections.

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.

If your dishwasher keeps filling with water at the bottom but doesn’t fill into the sink, the issue is likely due to a blockage within the dishwasher or drain. Regularly clean your dishwasher filter basket to ensure it’s not clogged with food, and run a vinegar rinse periodically if you have hard water to remove limescale buildup.

Most repairs take 1-3 hours, but complex issues requiring part replacements may take longer if parts need to be ordered.

To create a siphon break and remove any chance of dirty sink water or water that backs up into the sink from getting into your dishwasher, your dishwasher drain hose needs to have a high loop or an air gap device as part of its installation. All building codes require at least a high loop. In many places, it’s necessary to install an air gap device to meet the code.
