How to Clean a Dishwasher

How Does a Dishwasher Work?

How you clean dishwashers and the way dishwashers work can vary based on the make and model of the appliance. However, most dishwashers work similarly. Dishwashers have a wash cycle that starts by the dishwasher filling with water. The water is then heated, and the detergent, whether powder, liquid or pod, gets dispensed.

Then, water shoots through jets and mixes with the detergent to clean the dishes. The dirty water drains, the dishes get rinsed with clean water and the rinse water drains.

During the final stage, warm air circulates inside the dishwasher to dry the clean dishes. Because dishwashers are made to clean dishes, many people forget to take time to clean the dishwasher.

Why Is the Dishwasher Not Cleaning My Dishes?

If your dishwasher is not cleaning your dishes properly, first check your manufacturer’s guide to ensure you’re loading it correctly and using the right detergent, water temperature and settings.

Also, carefully scrape and rinse all dishes before they go into the dishwasher in order to remove as many food particles as possible.

Why Is the Dishwasher Not Draining?

If your dishwasher isn’t draining, there could be a clog in the kitchen drain due to food or grease buildup. Check your kitchen drain for a blockage, then use Liquid-Plumr® Clog Destroyer Plus+ Pipeguard™ to clear the clog.

If your dishwasher isn’t draining because of an issue unrelated to your kitchen sink, consult your user’s manual for tips.

But, if you have serious or persistent issues with your dishwasher, it’s best to seek the help of a professional plumber. For more information, check out this article about when to leave plumbing problems to the pros.

How Do You Clean a Smelly Dishwasher?

If you have a smelly dishwasher, you may not be rinsing your dishes properly before loading them. Food particles can collect in your dishwasher’s filter and crevices. Over time, this can lead to unpleasant odor.

One way to prevent debris from collecting is to thoroughly scrape and rinse plates, silverware, bowls, and other items before they go into the dishwasher.

Depending on the mess, you probably won’t need to scrub the plates with soap, but scrape food off and rinse dishes clean before loading your dishwasher. Failure to do this means large food particles can get caught in the grates (your dishwasher’s drainage system). This can result in clogs that prevent draining or result in a smelly dishwasher.

If there’s food caught in the drain system of your dishwasher, remove it. Then, use a clean sponge to wipe the area clean.

If you have a garbage disposal that smells, you can use Liquid-Plumr® Disposal & Drain Cleaner. It’ll help freshen the same plumbing the dishwasher uses and leave a fresh, citrus scent. For more information, check out How to Unclog a Garbage Disposal.
