Important Information About Dishwasher Plumbing

Dishwashers are a modern convenience that allow you to clean and sterilize your dishes after cooking and eating with no hassle. Using dishwashers has become so easy and efficient that often they can be operated at low cost with very little utility usage. What most people don’t know is that dishwashers have certain plumbing requirements that differ from other appliances in your home.

In this post, you will learn about common signs that your dishwasher needs plumbing services and how to prevent these issues. Using the knowledge and service of a plumber can help you keep your dishwasher operating at its peak for years to come.

Common Dishwasher Problems

Dishwashers are difficult to troubleshoot since it is difficult to watch them operate without flooding your home. However, noticing the signs that something is not right with your dishwasher can help you and your plumber determine what might be the cause of a dishwasher issue. Signs that your dishwasher isn’t operating properly can include:
  • Streaky Dishes
  • Noisy Operation
  • Leaks
  • Uncleaned Dishes
  • Undrained Water
  • Clogged Drains

Why Dishwasher Plumbing Is Special

Your dishwasher’s plumbing is special because it is an intersection of several different aspects of your home’s plumbing system. Hot water is supplied from your hot water tank to provide the medium to remove soil from your dishes. For the water to be effective, it needs to be soft. If you live in a region with hard water, using a water softener can boost the performance of your dishwasher.


Once the water is used in the dishwasher, it must be safely drained away. Most dishwashers are sealed into the plumbing underneath your kitchen sink. This is why drain problems can occur when the dishwasher is operating. If you have a garbage disposal, dishwasher drain water is usually piped to it with a hose.

Most building codes require that dishwashers be installed and maintained by licensed plumbers. Because dishwashers affect so many components of your home’s plumbing, it is important that a professional ensures proper installation.

Preventing Dishwasher Problems

Most dishwasher problems are easily solvable, but sometimes the source of the problem is surprising and can come from a lack of cleaning your dishwasher. The following list designates the most likely culprits for dishwasher problems and includes information on preventing issues in the future.

  • Garbage Disposal: In a typical home, dishwasher drain lines are tied into your garbage disposal. Clogged sink drains and garbage disposals prevent dishwasher drain water from draining properly and can cause dirty water to back up into your kitchen sink. Keeping drains clean by running the garbage disposal and flushing it with hot water can prevent the dishwasher’s drain water from backing up.
  • Hot Water Tank: Hot water tanks must supply the correct temperature of water to allow the dishwasher to operate properly. Checking the tank temperature can ensure this happens. Additionally, draining and flushing the hot water tank annually can prevent hard water scale from making it to your dishwasher.
  • Water Softener: Water softeners prepare the water for the dishwasher by removing minerals from it. Hard water prevents detergents from properly rinsing away. Checking that your water is soft will help your dishes get clean and shiny.
