Is Your Dishwasher Not Draining? Here's How to Clean the Filter
Introduction
The dishwasher filter is one of the most important parts of your dishwasher that you need to periodically clean and maintain. Cleaning this filter on a regular basis helps improve your dishwasher's performance and efficiency.
Over time, pieces of food and hard water minerals will get trapped in the filter. When the filter becomes clogged with debris, it prevents your dishwasher from getting adequate water circulation during its wash cycles. As a result, dishes won't get properly cleaned.
By giving your filter a periodic cleaning, you allow water to freely circulate throughout the dishwasher. The cleaned filter also ensures no food particles can clog the spray arms. This helps optimize cleaning performance.
It's recommended to clean the filter at least once every 30 days. If you have hard water, you may need to clean the filter more frequently. Doing so takes just a few minutes and goes a long way towards keeping your dishwasher in good working condition.
Locate the Filter
The dishwasher filter is typically located at the bottom of the dishwasher tub. However, the exact location can vary slightly depending on the dishwasher model.
For front-control dishwashers, the filter is usually found at the bottom center of the tub. Look for a cylindrical plastic cap that can be twisted off to access the filter.
For top-control models, the filter is often located behind the lower spray arm. You'll need to remove the spray arm to get to the filter. There may be a cap or cover that needs to be removed as well.
For older models, the filter may be positioned at the back of the tub. Check for a panel or grate that can be popped out or unscrewed.
Regardless of position, the filter is designed to catch food debris and prevent it from being redeposited on dishes during the wash cycle. Finding and cleaning this filter regularly is key to optimal dishwasher performance.
Remove the Filter
To remove the filter, follow these simple steps:
1. Locate the bottom panel of your dishwasher. This is usually found at the front base of the dishwasher tub.
2. Release any clasps or screws holding the panel in place. You may need a screwdriver for this.
3. Gently pull off the panel to access the filter inside. Be careful not to break any plastic clips.
4. Locate the cylindrical filter within the compartment. It is often white or gray in color.
5. Turn the filter counterclockwise to unlock it from the fitting. You may need to give it a good twist to break the seal.
6. Pull down and remove the entire filter. Take care not to drop any debris as you remove it.
7. Set the filter aside in an area where it will not get contaminated. You are now ready to thoroughly clean the filter.
Clean the Filter
The most effective way to clean the dishwasher filter is to use a mixture of white vinegar and warm water. Here are the recommended steps:
1. Remove any large debris from the filter like food scraps, bones, etc. This can usually be done by hand.
2. Fill a bowl or sink with equal parts warm water and plain white vinegar. Let the filter soak in the mixture for 5-10 minutes. This will help loosen and dissolve any hard water deposits or grease buildup.
3. Use a soft brush or sponge to gently scrub the filter under the water. Focus on any stubborn areas of residue. Avoid using anything abrasive that could scratch the filter.
4. Rinse the filter thoroughly with warm water to remove the vinegar solution.
5. You may need to repeat steps 2-4 if the filter is very dirty. Let it soak longer and scrub more vigorously if needed.
6. Once cleaned, inspect the filter closely to ensure it is free of debris before replacing it in the dishwasher.
The vinegar and water method is highly effective at cleaning dishwashers filters. Vinegar is a natural cleaner that breaks down mineral deposits from hard water and dissolves grease. Be sure to rinse it thoroughly so it doesn't affect your next load. With regular care, your filter will stay clean and allow your dishwasher to operate at peak performance.
Inspect and Replace
Once you have thoroughly cleaned the filter, take some time to inspect it before placing it back into your dishwasher. Look for any cracks, tears, or holes in the mesh material. Check the edges and make sure the rubber seal is still intact. Examine the entire filter for any debris that didn't come off during cleaning.
It's also a good idea to inspect the filter housing before replacing the filter. Look for any damage or wear. Make sure the housing is free of any leftover debris. Confirm the filter can lay flat and sit securely in place when returned to the housing.
Only replace the filter if it is in good condition with no damage. A faulty or worn filter will allow debris to bypass and cause issues. If the filter has any cracks, holes, or tears it needs to be replaced. Most dishwasher filters should be replaced every 2-3 years or so with regular use. Consult your owner's manual if you notice it needs replacing more frequently.
When placing the filter back into the housing, be sure it lays flat and the seal is tight within the housing. Lock it back into place correctly. Double check that the filter is fully secure before running your dishwasher again. If it is loose, it could move around and allow debris buildup internally. Taking the time to properly inspect and replace the filter will maximize its lifespan.
Replace the Filter
After cleaning the filter, it's time to put it back in place. Follow these steps:
1. Check that the filter is completely dry before replacing it. Any moisture left on the filter could lead to mold growth.
2. Examine the filter for any cracks or damage. If it is worn out, replace it with a new one.
3. Insert the filter back into its housing. It should fit snugly in place.
4. Make sure the filter is seated flat in the housing. If it is at an angle, it could dislodge when water flows through it.
5. Push the filter in as far as it will go. There should be no gaps between the filter and the housing.
6. If your dishwasher has a cover for the filter, replace it now. The cover helps keep the filter securely in place.
7. Double check that the filter is correctly installed before using the dishwasher again. Wiggle it gently to confirm it is locked in position.
8. Run an empty load to verify there are no leaks or issues with water flow. Monitor the cycle to ensure proper drainage.
Replacing the filter correctly is crucial for ensuring debris does not get into the dishwasher's pump and clog it. Taking a minute to properly reinstall the filter will save you headaches down the road.
Reset Dishwasher
After replacing and securing the filter, you may need to reset your dishwasher. This ensures the dishwasher recognizes the filter has been cleaned and is back in place.
The steps to reset your dishwasher:
- Close the dishwasher door securely.
- Press and hold the heated dry button for 4 seconds until the clean light flashes. This indicates the reset cycle has started.
- Let the dishwasher run through the reset cycle, which takes about 10 minutes. Do not open the door during this process.
- When the clean light stops flashing, the reset cycle is complete.
- Run a normal wash cycle with no dishes inside to ensure proper operation.
Resetting the dishwasher after changing the filter clears any residual error codes or faults related to the clogged or missing filter. It rebalances and recalibrates the dishwasher to operate properly.
Maintenance Schedule
How often you need to clean your dishwasher filter depends on how frequently you use your dishwasher. Here are some general guidelines on maintenance frequency:
- Light Use - Once Every 2-3 Months: If you run your dishwasher just a few times per week, a good rule of thumb is to clean the filter every 2-3 months. This helps prevent any debris buildup over time.
- Moderate Use - Monthly: For moderate use of about 5-7 times per week, aim to clean your filter about once a month. Monthly cleaning will keep the filter clear of obstructions.
- Heavy Use - Biweekly: With heavy use of multiple cycles per day, clean the filter every 2 weeks. Frequent use means more food particles and grease passing through, so biweekly cleaning is ideal.
- Signs of Clogs - As Needed: Regardless of use frequency, clean your filter as soon as you notice signs of clogging like dirty rinse water, dishes not getting clean, or slow drainage. Don't wait for your regular schedule if the filter needs cleaning.
- When Unloading - Quick Rinse: Get in the habit of giving your filter a quick rinse when unloading clean dishes. This minor maintenance helps prevent buildup between deep cleanings.
Following these general guidelines will keep your filter clear of debris for optimal performance. Adjust as needed based on your dishwasher's condition. Proper care promotes a longer lifespan.
Troubleshooting
If you are still experiencing issues with your dishwasher even after cleaning the filter, there are a few common problems to check:
- Clogged or blocked spray arms - Check that the spray arms can rotate freely without obstruction. Remove any food particles or debris blocking the water spray.
- Faulty drain pump - The drain pump helps remove water from the dishwasher tub. If it's not working properly, water can remain stuck in the dishwasher. Check for any leaks or noises from the drain pump.
- Clogged impeller - The impeller is part of the pump assembly that pushes water through the spray arms. Limescale buildup or small objects can clog the impeller, so it's a good idea to clean it when you notice any dishwasher issues.
- Bad door latch - The door latch ensures the door is properly closed and sealed during operation. If it's damaged, the dishwasher may not fill or drain properly. Try adjusting or replacing the latch.
- Bad control board - The control board is the 'computer brain' of the dishwasher and controls thewash cycles. If it's faulty, the dishwasher may not start or complete cycles properly. You may need a technician to diagnose and replace the control board.
- Drainage issues - Problems with the drain hose, air gap, or kitchen plumbing can prevent proper drainage. Check for kinks, clogs, or backflow issues.
- Water inlet issues - Issues with the water inlet valve or water supply line can prevent the dishwasher from filling properly. Check the valve, gaskets, and hoses.
If you've tried the common fixes but your dishwasher still has problems, it's a good idea to have an appliance repair technician diagnose and service it. Certain issues like control board failure or drainage problems may require a professional to properly repair.
