Dishwasher Installation questions, answered by experts

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.

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.

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.

The correct water temperature for your dishwasher depends on the washing phase. When water enters the machine, it should be around 120 degrees Fahrenheit, but no hotter than 150 degrees. During the wash cycle, the machine will heat the water to between 130 and 140 degrees. If your dishwasher has a sanitizing cycle, the water can reach a temperature of up to 180 degrees.

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.
