Common Dishwasher Service Questions

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, even a small dishwasher leak is a big deal. While it might seem minor, continuous unnoticed drips can lead to significant water damage to your kitchen floor, subfloor, and cabinetry. This damp environment is also a perfect breeding ground for mold, which can cause health issues and expensive mold remediation. Remember that water and electricity don't mix—having even a small leak poses a potential electrical hazard. Addressing any leak as soon as possible protects your home and avoids costly future repairs.

Depending on your available time and skillset, there are some aspects of dishwasher repair you can DIY. Remember that dishwashers use water and electricity, which can cause potentially hazardous situations. However, there are some things you can do to reduce your overall repair cost, such as:

  • Cleaning the spray arm

  • Unclogging the float

  • Replacing the door gasket

  • Cleaning the door filter

  • Adjusting the door latch

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.

When a dishwasher discharges its wastewater, it uses a pump to quickly move a lot of water. If anything in the drain line or the garbage disposal impedes the high volume of water, it will back up into the sink through the drain or the garbage disposal. Following regular dishwasher maintenance tips like clearing clogs, keeping them cleared, and occasionally running the disposal will eliminate the problem.
