Dishwasher Installation questions, answered by experts

Yes, a dishwasher needs an air gap to prevent backflow. Additionally, in many locations, air gaps or another measure to prevent backflow are required for building code compliance. There are alternatives to an air gap, like a Studor vent or a loop and trap design, but an air gap is the simplest and most popular solution.  

A clogged air gap can cause a dishwasher not to drain. There are, however, other potential issues that can lead to improper drainage. For example, if you have attached the air gap to a garbage disposal and forgotten to remove the knockout plug, wastewater may backflow into the dishwasher. Check that the air gap is installed properly, and then look for clogs in the air gap and dishwasher filters. 

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.

Professional repair is advisable for electrical issues, refrigerant leaks, or unfamiliar problems. Technicians can accurately diagnose and fix such problems, ensuring safety and appliance longevity.

There are some dishwasher care tips to extend its longevity and keep your dishes sparkling. Not overloading your dishwasher is key to letting water and soap move freely through the unit. Too much soap can stress your dishwasher unnecessarily, causing it to break down sooner. 

Cleaning your dishwasher is essential for its performance, so every three to six months, put two cups of white vinegar in a dishwasher-safe cup on the top rack and run a complete cycle. When done, place ¼ cup of baking soda inside and run a short cycle to eliminate any lingering odors.
