How Often to Clean a Dishwasher Drain

Cleaning your dishwasher drain is an important part of maintaining your kitchen and keeping it clean. Not only does it help reduce the amount of grime and bacteria, but it can also prevent the formation of foul odors. To ensure your dishwasher remains in good working order, it’s important to know how often to clean your dishwasher drain.

Fortunately, cleaning your dishwasher drain isn’t difficult. With just a few simple steps, you can keep your dishwasher running smoothly and safely. Here are four steps on how often to clean your dishwasher drain:

1) Empty the Dishwasher

Empty the Dishwasher

If you want to effectively clean your dishwasher drain, the first step is to empty the dishwasher. Make sure you remove all dishes, utensils, and other items from the dishwasher. Once everything is out, take a look inside and make sure there is nothing left in the bottom of the dishwasher.

If you see any food particles or other debris, use a damp rag to wipe it away. You can also use a pair of tongs or a spatula to help remove stubborn pieces of food.

After you have finished emptying the dishwasher, run it on a hot cycle to flush out any remaining debris or food particles. This will also help to sanitize the inside of your dishwasher and make sure it is clean and free of germs.

Be sure to use the hottest setting available on your dishwasher so that the water is hot enough to completely dissolve any remaining particles. This will also help prevent any clogging or buildup in the future.

2) Clean Dishwasher Drain Filter

Your dishwasher drain filter is an important component of your kitchen. It helps to keep your dishwasher clean and running smoothly by trapping food particles, dirt, and other debris that would otherwise clog up the system.

Unfortunately, over time your dishwasher drain filter can get clogged and needs to be cleaned. This can be a daunting task if you don’t know what you’re doing.

Thankfully, we’ve got you covered with our five easy steps to cleaning your dishwasher drain filter.

  • First, unplug your dishwasher and turn off the water supply. Make sure to put a towel at the base of the dishwasher to absorb any water that might come out when you open the drain filter.
  • Carefully remove the drain filter by unscrewing the cover and pulling it out. Check for any debris or obstructions that may have collected inside the filter.
  • Rinse the drain filter in a bucket filled with warm water and a small amount of dish soap. Make sure to scrub away any caked-on food or dirt that might be stuck on it.
  • Once the filter has been cleaned, place it back into the dishwasher and secure it with the screws.
  • Lastly, turn on the water supply and plug the dishwasher back in.

Congratulations! You’ve successfully cleaned your dishwasher drain filter and it should now be working better than ever.

3) Unclog Dishwasher Drain

Dishwashers are an essential part of any home, but if you don’t keep your dishwasher drain clean and clear, it can become clogged with debris. Fortunately, with a few simple steps, you can unclog your dishwasher drain and get your dishwasher running smoothly again.

  • Start by turning off the power to your dishwasher. This will prevent any potential shocks while you are working on the drain.
  • Next, locate the drain hose. It’s usually underneath the sink or at the back of the dishwasher. You may need to use a flashlight to get a good view of the area.
  • Now that you’ve found the drain hose, remove it from the drain. Inspect it for any blockages, such as food particles or soap residue. If you find any, use a stiff brush to remove them.
  • With the drain hose removed, locate the dishwasher filter and remove it as well. Use a soft brush to remove any debris that has collected in the filter.
  • Finally, reattach the hose and filter and turn the power back on. If your dishwasher is still draining slowly, you may need to run a cycle with vinegar or baking soda to help clear out any remaining debris.

By following these five steps, you can unclog your dishwasher drain and get your dishwasher running like new again!

Clogged dishwashers are a common household problem that can cause a lot of inconvenience and mess. Fortunately, you can remove the clog yourself with some basic tools and a little bit of know-how. Here are five steps on how to clean your dishwasher drain hose.

  • Turn off power supply for your dishwasher at the circuit breaker or remove power plug.
  • Remove the lower spray arm from inside dishwasher using a screwdriver and then unscrew it from its base below the sink (using pliers).
  • Take out one end of the water hoses attached to your kitchen sink’s faucet connection and place it in an empty bucket or container (to catch any water leakage).
  • Pull out any clogs found in either end of the hose (by hand) if possible or use pliers or screwdriver as necessary.
  • Turn on faucet again after draining water out of hoses so you have enough water pressure to reconnect them back together again before putting everything back in place inside dishwasher’s interior components including its upper spray arm which was removed previously during step two above


Cleaning your dishwasher drain can be a daunting task, but with the right steps, you can get it done quickly and easily. With the five steps outlined in this blog post, you’ll have your dishwasher drain working like new in no time.

Q. What is the best way to clean dishwasher drain?

A: The best way to clean dishwasher drain is by using a commercial dishwasher cleaner or by using a half cup of salt and half cup of vinegar, then pour them into the bottom of the dishwashing machine and leave it overnight. The next day, use water in the bottom of the machine to rinse it out, then run a full cycle without dishes inside.

Once you have completed this process, if you still see build-up on your sink trap beneath your sink and/or are experiencing drainage issues from your dishwasher or from under your sink, contact an expert for assistance with cleaning the entire plumbing system in your house or business.

Q. Is it safe to use bleach in a dishwasher?

A: While bleach is a powerful cleaner, it should never be used in a dishwashing machine. Bleach is too harsh for the internal parts of the dishwasher and could cause damage to the seals and other components. If you’re looking for a powerful cleaning agent to use, opt for a commercial dishwasher cleaner or baking soda instead.

Q. Why does my dishwasher smell like sewage?

A: One possible reason for your dishwasher smelling like sewage is that someone put food waste down the drain that’s not supposed to go there. Another reason may be that the plumbing in your home isn’t installed properly and there’s a backflow problem.

Finally, it could also be because there’s something stuck in the disposal grate at the bottom of the dishwasher that needs to be removed so that water can circulate freely through your pipes again.

Q. I think I know what’s wrong with my dishwasher but I’m not sure how to fix it. Do you have any suggestions?

A: Yes! We’ve seen several instances where people were able to clear their plumbing blockages by doing one simple thing – they turned off the water valve under their kitchen sink. There might be something in your line that’s restricting the flow of water, which means turning off the main water supply before attempting anything else.

With everything turned off, remove any objects that could be obstructing things before turning everything back on and checking for clogs one more time. For help with installation problems, call an experienced plumber as soon as possible – this is definitely a job for professionals!
