How Do You Clean the Filter On a Whirlpool Dishwasher?

Over time, the filter can become clogged with dirt and grime, leading to bad smells. Are you wondering how to clean a Whirlpool dishwasher filter?

To clean the filter on your dishwasher, follow these steps:
- Remove the lower rack and unscrew the filter housing cap
- The dishwasher filter is typically found in the back corner or the base of the dishwasher tub. Gently turn the upper filter clockwise to remove it.
- Unscrew the filter from the housing
- Rinse the filter with warm water to remove any dirt and grime.
- For stubborn debris deposits, use a soft brush and dish soap to scrub the filter clean.
- Replace the filter and screw it back into place
How Do You Run a Clean Cycle On a Whirlpool Dishwasher?
Cleaning your dishwasher is simple and can be done in just a few steps. You can also clean the dishwasher with vinegar. First, you will need to remove any dishes or food items from the appliance’s interior. Next, add one cup of white vinegar to the bottom of the dishwasher and run a normal cycle on hot water. The vinegar will help remove grease and food particles from the dishwasher’s interior.

If you have an automatic detergent dispenser, add Affresh Dishwasher Cleaner to the compartment and run a normal cycle on hot water. During this process, it is best to ensure the dishwasher is empty of any dishes. This cleaner is specifically designed to clean dishwashers and will help remove any lingering debris and odors.
Once the cycle is complete, wipe down the dishwasher’s interior with a clean cloth to remove any remaining vinegar or cleaner.
How Do You Unclog a Drain on a Whirlpool Dishwasher?
If your dishwasher isn’t draining properly, it’s likely because the drain is clogged. A clogged dishwasher drain indicates the need to learn how to clean a Whirlpool dishwasher correctly. Are you wondering how to clean a clogged Whirlpool dishwasher?
To unclog a drain on your dishwasher, follow these steps:
- Start by pouring a cup of white vinegar down the drain. Let the vinegar sit for 15 minutes to break up any clogs.
- Next, pour a cup of baking soda down the drain and let it sit for another 15 minutes.
- After the baking soda has had time to work, pour a pot of very hot water down the drain to flush out any remaining debris.
If your dishwasher still isn’t draining properly, you may need to remove the drain hose and clean it out with a wire brush.
It’s important to clear out the garbage disposal before every dishwasher cycle to prevent clogs. To do this, simply pour in a pot of hot water and run the disposal for about 15 seconds.
The air gap is an important part of your dishwasher’s drainage system. If it becomes clogged, the dishwasher won’t be able to drain properly. Check and ensure the air gap is cleared of any blockages before running your dishwasher.
How Do You Prevent Water Spots on Glassware?
One of the most frustrating things about doing dishes is finding water spots on your clean glassware. But there’s an easy way to prevent this from happening. Simply add a rinse aid such as Jet-Dry to your dishwasher’s detergent compartment. Rinse aids help to reduce surface tension, which prevents water from beading up on your dishes and causing spots.

That’s it! These simple tips will help keep your dishwasher smelling fresh and running properly.
