Dishwasher Installation questions, answered by experts

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.

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.

Not all dishwashers are 60cm wide, but that tends to be the most common size. 60cm translates into roughly 24 inches, with most home dishwashers being between 22 and 24 inches wide. There aren’t metrics available but it’s been our experience that over 90% of household dishwashers in North America are around 24 inches wide by 24 inches tall.

Most repairs take 1-3 hours, but complex issues requiring part replacements may take longer if parts need to be ordered.
