How To Clean Smelly Dishwasher

Nobody likes a smelly dishwasher, but it’s an all too common problem. A dirty and stinky drain hose is often the source of the issue. If you’re dealing with a smelly dishwasher and are looking for an easy solution, don’t worry! Cleaning your dishwasher’s drain hose is simpler than you think, and with just a few simple steps you can have your dishwasher smelling fresh again in no time.

A smelly dishwasher drain hose can be a nuisance in any kitchen. Not only can it stink up the room, but it can also cause hygiene issues that could potentially make you sick. Cleaning your smelly dishwasher drain hose is an easy task that doesn’t take long and will have your kitchen smell, clean and fresh in no time. Here are some tips on how to clean your smelly dishwasher drain hose.

The first step is to disconnect the dishwasher from its power source before cleaning the hose. Once disconnected, carefully pull out the drain hose from its connection point under the sink or countertop and place it into a bucket of warm water with a few drops of liquid soap added to it. Leave this solution for at least 10 minutes as this helps to loosen any dirt, grime, food particles or grease build-up inside the pipe.

Smells can be a nuisance, but they can also be indicative of underlying issues. A smelly dishwasher drain hose is no exception and can point to causes that may need attention in order to restore comfort to the home. If a dishwasher’s drain hose emits an unpleasant smell, it is important to identify the source quickly so that proper cleaning and maintenance processes can be employed for complete odor removal.
One common cause of smell from the dishwasher drain hose is the buildup of food particles or grease in the pipe itself. As these substances accumulate over time, bacteria will begin to form which creates an unpleasant smell that could spread throughout the house if not addressed promptly. To prevent this from occurring, regular inspections should be conducted along with periodic deep cleans and flushes of the drainage system so food particles do not have a chance to build up.

Step 1: Remove Hose and Inspect

When it comes to cleaning a smelly dishwasher drain hose, the first step is to simply remove and inspect the hose. Doing so will ensure that any build-up of debris or food particles can be removed before further cleaning steps are taken. To remove the hose, start by unplugging the dishwasher from its power source and locate the drain line connection at either end of the hose. Carefully slide off any clamps securing the ends of the hose and gently pull out both ends completely.
Once removed, inspect each end for any blockages caused by leftover food particles or other debris. If there’s build-up, gently scrape away with a putty knife or similar tool until it’s gone. Afterward, you can use an old toothbrush to make sure no residue remains inside either end of the hose.

Step 2: Clean Out the Drain

When it comes to proper dishwasher maintenance, cleaning out the drain is an important step. A smelly dishwasher can not only be a nuisance but could also be unhealthy. Taking the time to clean out the drain hose can help keep your dishwasher smelling fresh and running efficiently.
Begin by unplugging any electrical connection from the wall and turning off any water supply to your dishwasher. Pull the appliance away from its wall installation and locate where the drain hose connects to a garbage disposal or air gap in your sink. From there, you will want to remove any clogs that may be blocking water discharge flow with a plumber’s snake or similar tool. After removing debris, flush out both ends of the hose with hot water and use a brush if needed to scrub away residue build-up inside the hoses.

Step 3: Sanitize the Hose

The third and final step in cleaning a smelly dishwasher drain hose is to sanitize it. When dealing with wastewater, it’s important to take the necessary precautions to ensure that the environment stays clean and safe. Sanitizing the hose will help prevent any bacteria or other microbes from lingering in the system and causing future problems.
Start by draining the remaining water out of the dishwasher hose using a bucket or container. Once all of the water has been emptied, mix one part white vinegar with two parts warm water in a spray bottle. Spray this mixture liberally onto both sides of the hose, then let it sit for at least 15 minutes before rinsing off with cold water. This will kill any germs that may have been living inside of it and give your dishwasher drain line a fresh start!

Step 4: Reinstall Hose

When it comes to the dishwasher, one of the most common problems people face is a smelly drain hose. Fortunately, you can quickly and easily fix this issue with just a few simple steps. Step 4 in this process is to reinstall the hose, and here’s how to do it.
To start off, make sure that your hose is completely clean before installing it again. You can use a mixture of hot water and bleach to get rid of any lingering odors or dirt that may be stuck on the hose itself. Then, simply attach one end of the hose back into the dishwasher outlet while ensuring that there are no kinks or bends in the line. Once connected securely, move on to connecting the other end back into your sink drain pipe and secure it tightly with clamps or tape if necessary.

Step 5: Use Preventative Measures

Preventing a smelly dishwasher is often the most effective and cost-efficient way to keep your kitchen odor-free. Step 5 of cleaning a smelly drain hose involves using preventative measures to ensure that odors are kept at bay.
To start, it’s important to regularly clean the inside of the dishwasher by running an empty cycle with hot water and a bit of vinegar. This helps remove all traces of food particles and grease stuck in the walls, filters, and drainage system, preventing bacteria from multiplying and creating bad odors. Additionally, you should make sure that the drain hose is cleaned properly on a regular basis. This can be done by removing any debris that may be stuck in or around it, such as food pieces or other organic materials like pet hair which can cause bacteria and mold growth.


Cleaning your dishwasher regularly is essential to maintaining a healthy and clean home. Regular maintenance and cleaning will help to keep your dishwasher running smoothly, reduce bacteria and mold, and prevent odors. Try using natural cleaners such as baking soda, vinegar, or lemon juice to clean your dishwasher instead of harsh chemical cleaners. Additionally, focus on preventive measures such as scraping off large food particles before loading the dishwasher to decrease the amount of grime build-up in the machine.
