Excellent service by Lakendra, who repaired our dishwasher. She was professional, friendly, efficient and exceptionally tidy on the two occasions she came. She was right on time and kept us informed regarding her time of arrival. Highly recommend Lakendra!

Dishwasher Installation questions, answered by experts

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.

Local plumbing codes and manufacturer recommendations typically dictate the minimum distance between a sink and a dishwasher. This is generally 18 to 24 inches, providing enough room for easy loading and unloading of dishes without hindering the sink's function. Maintaining this separation not only adds convenience but also reduces the chances of water damage and optimizes plumbing connections.

Repair costs vary by issue, typically from $100 to $500, depending on the parts needed and labor involved.

Some common signs you have a dirty dishwasher filter are:

Food sticking to your dishes even after a thorough wash cycle
Odor coming from your dishwasher
Stains left on dishes and utensils
Water pooling in your dishwasher
Food stuck to parts of the dishwasher, like the racks, walls, or sprayer arm

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.
