Very professional. They will come out and give you a diagnosis for $80 for the DIYer who can't quite figure out the problem. I had Dakota check the level of the dishwasher while he was here. Very nice and COVID conscience. I will hire them again!

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.

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

If your dishwasher keeps filling with water at the bottom but doesn’t fill into the sink, the issue is likely due to a blockage within the dishwasher or drain. Regularly clean your dishwasher filter basket to ensure it’s not clogged with food, and run a vinegar rinse periodically if you have hard water to remove limescale buildup.

Yes, vinegar is an excellent homemade solution to clean a dishwasher. Its acidity will cut through any buildup, while its natural deodorizing capabilities will take care of any nasty smells.

DIY installation or repair is possible with the right skills and tools, but if not done correctly, it can often lead to water leaks or improper connections.
