### How to Clean a Whirlpool Dishwasher Filter: A Simple Guide
Maintaining your Whirlpool dishwasher is essential for keeping your dishes spotless and your appliance running smoothly. One crucial yet often overlooked task is cleaning the dishwasher filter. Over time, food particles, grease, and debris can clog the filter, leading to poor cleaning performance, unpleasant odors, and even potential damage to the appliance. This detailed guide walks you through the step-by-step process of cleaning your Whirlpool dishwasher filter, offers practical tips for maintenance, and answers common questions to ensure your dishwasher stays in top shape.
#### Why Cleaning Your Whirlpool Dishwasher Filter Matters
The filter in your Whirlpool dishwasher plays a vital role in its operation. It traps food debris and prevents it from recirculating onto your dishes or clogging the pump and drain system. According to Whirlpool’s official product help page, “Keeping your dishwasher filter clean is one key to avoid cloudy glassware and maintain sparkling dishes” [((Whirlpool Product Help))]. A clogged filter can reduce water circulation, leave residue on dishes, and even cause drainage issues. Regular cleaning not only enhances performance but also extends the lifespan of your appliance.
Experts at Sears Home Services emphasize, “Regularly cleaning the filter in your Whirlpool dishwasher ensures that it operates properly and efficiently. A clogged filter can block water flow and inhibit cleaning” [((Sears Home Services))]. Whether you notice gritty dishes or a funky smell, cleaning the filter is a simple fix that delivers big results.
#### Step-by-Step Guide to Cleaning Your Whirlpool Dishwasher Filter
Most Whirlpool dishwashers feature a two-part filter system—an upper filter assembly and a lower filter—located at the bottom of the tub. Here’s how to clean it effectively:
##### Step 1: Prepare Your Dishwasher
Before you begin, ensure the dishwasher is turned off and unplugged for safety. Open the door and slide out the lower dish rack to expose the bottom of the appliance. This gives you clear access to the filter area.
##### Step 2: Locate the Filter
The filter is typically found in one of two spots: either in a back corner of the dishwasher tub or around the base of the bottom spray arm. Whirlpool explains, “The filter can be found in either a back corner of the dishwasher tub or around the base of the bottom spray arm. Many dishwasher filters are composed of two parts: an upper and lower filter assembly” [((Whirlpool.com))]. Look for a cylindrical or flat mesh component—that’s your filter.
##### Step 3: Remove the Filter
– **Upper Filter Assembly**: Give the upper filter a quarter turn counterclockwise and lift it out. It’s designed to keep oversized items and fine particles out of the pump.
– **Lower Filter**: Grasp the lower filter in the circular opening, lift slightly, and pull it forward to remove it. This part prevents food from redepositing onto your dishes.
Be gentle during removal to avoid damaging the filter. If it’s stuck, double-check for any clips or twist-lock mechanisms specific to your model.
##### Step 4: Clean the Filter
Take the filters to your sink and rinse them under warm running water to remove loose debris. For stubborn grime like calcium deposits or stuck-on food, Whirlpool advises, “As you wash the dishwasher filter, you may need to use a soft brush and dish soap on calcium deposits and other hard-to-remove food debris. Don’t use a wire brush, scouring pad or anything rough to scrub the filter as these materials could damage the filter.” A soft toothbrush works wonders here.
For an extra deep clean, Dan Marc Appliance suggests soaking the filters: “Soak the spray arms in a solution of detergent and warm water. This will help to loosen any grime or debris” [((Dan Marc Appliance))]. You can apply this method to the filters too—just let them sit for about an hour before scrubbing.
##### Step 5: Inspect and Reinstall
Check the filters for cracks or wear. If they’re damaged, replace them with a Whirlpool-approved part specific to your model (available on the Whirlpool replacement parts site). To reinstall:
– Place the lower filter under the locating tabs at the bottom of the tub, aligning it with the circular opening.
– Fit the upper filter into the opening on top of the lower filter and turn it clockwise until it locks into place. Whirlpool warns, “If the filter still turns freely, it’s not seated properly. Keep turning it clockwise until it locks.”
##### Step 6: Test Your Dishwasher
Replace the lower rack, close the door, and run a short cycle with no dishes to ensure everything is working correctly. This flushes out any remaining debris and confirms the filter is secure.
#### How Often Should You Clean the Filter?
The frequency depends on your usage and water quality. Sears Home Services offers this guidance: “It’s advisable to clean your dishwasher filter every three to six months. This timeframe allows for the accumulation of debris that could clog the filter and affect the dishwasher’s cleaning ability.” However, if you notice signs like foul odors, gritty dishes, or reduced water pressure, clean it sooner. For heavy use or hard water conditions, monthly cleaning might be necessary.
#### Bonus Tips for Dishwasher Maintenance
Cleaning the filter is just one part of keeping your Whirlpool dishwasher in peak condition. Here are some additional tips:
– **Clean the Spray Arms**: Remove and soak them in warm soapy water, then use a toothpick to clear clogged jets. This ensures water flows freely.
– **Run a Vinegar Cycle**: Place a bowl of white vinegar on the top rack and run a hot cycle to break down grease and mineral buildup.
– **Wipe the Seals**: Use a soapy cloth to clean the door seals, where bacteria and mildew can hide.
– **Use a Cleaner**: Products like Affresh Dishwasher Cleaner, recommended by Whirlpool, can tackle odors and spotting when used monthly.
#### Troubleshooting Common Filter Issues
If your dishwasher still isn’t performing well after cleaning the filter, consider these possibilities:
– **Standing Water**: A clogged filter or drain hose might be the culprit. Check the hose under the sink and clear any blockages.
– **Filter Won’t Lock**: Ensure it’s aligned with the tabs and turned fully clockwise. A loose filter can damage the appliance.
– **Persistent Odors**: Run a cycle with baking soda sprinkled on the bottom after a vinegar rinse for a fresh scent.
