Dishwasher Installation questions, answered by experts

Basic maintenance, such as cleaning filters, is DIY-friendly, but repairs involving electrical components, pumps, or valves should be handled by a professional.

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.

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.

Not all dishwasher noises are signs of trouble, as dishwashers naturally make sounds during operation. Normal sounds for a functional dishwasher include humming, swishing, and sloshing. However, if you hear problematic noises such as pounding, drumming, grinding, or rattling, it could be a sign of an underlying issue, and you should consider having a technician inspect your appliance.

Leaks, poor drainage, failure to start, water not heating, and excessive noise frequently require service.
