How to clean dishwasher pipes

Here are some of the most straightforward solutions for how to clean dishwasher pipes. You will find both homemade solutions and exclusive cleaning products, such as the Finish Dual Action Dishwasher Cleaner, you can get from Amazon right now!

Why do dishwasher pipes need cleaning

Along with our dishes, we put a lot of other things into our dishwashers as well. This includes food particles, grime, oils, and sometimes even the accidental food wrappers. All of this can cause clogging of the dishwasher pipes and the dishwasher drain, which must be cleaned to make the dishwasher run smoothly again.

However, keep in mind that before cleaning your dishwasher pipes and drain, it is imperative to turn off the power supply to your dishwasher to avoid any risk of injury.

How to clean the dishwasher pipes using baking soda and vinegar

Often, your dishwasher pipes may be clogged up with food residue, dirt, oil, and grime, which are causing the dishwasher water to back up into the dishwasher. Clearing out the dishwasher drain with baking soda and vinegar can be a quick and effective solution.

  1. Create a solution of white vinegar and baking soda and put it in a small container. Pour the mixture on the bottom of your dishwasher.
  2. Allow it to sit for about 15 minutes.
  3. Add some hot water (not boiling water) to the dishwasher basket. This should help loosen up any grime, oils, and debris and clean out any clogs in your dishwasher pipe.
  4. You can repeat this process once a month to keep your dishwasher running smoothly.

How to clean the dishwasher pipes and drain with a wire hanger

Sometimes stubborn food particles get stuck up or jammed in your dishwasher drain. These are not easily washed away with hot water, or even vinegar and baking soda. In this case, you will have to clean out the dishwasher pipe manually.

  1. Turn off the power supply to your dishwasher before you begin.
  2. Bring out your owner’s manual of your dishwasher and go through it to understand the anatomy of your dishwasher.
  3. Locate the dishwasher pipe, and using pliers, gently disconnect the dishwasher hose from the basin. You should ideally keep a bucket or a bowl underneath the hose when you do this so that the bucket can catch any water and spills from the dishwasher pipe.
  4. Now, take a wire hanger and push it into the dishwasher drain pipe, trying to remove any stubborn residue, hair, grime, or other stuck particles. You should wear protective gloves and mask while doing this to avoid touching the dirt or breathe in any bad odors. 
  5. Once you have cleared out the debris, you can run some hot water through the dishwasher pipe to clean out any remnants.
  6. Attach the dishwasher pipe back to your dishwasher and use it again!

How to unclog the dishwasher drain using high-pressure water

An alternative way to clean your dishwasher pipe after disconnecting it from the basin would be to use high-pressure water through the pipeline.

  1. Disconnect the dishwasher pipe, and run a high-pressure water hose through the pipeline.
  2. This will effectively clear out any dirt, grime, and debris from the pipe.
  3. Reattach the dishwasher pipe to your dishwasher and run it without any dishes for once cycle, to really clean up any residue from your dishwasher pipe. High-pressure cleaning can be one of the best methods for good dishwasher maintenance.
