### How to Clean a KitchenAid Dishwasher Filter: A Detailed Guide
Maintaining your KitchenAid dishwasher is essential for ensuring it performs at its best, and one of the most critical components to keep clean is the filter. Over time, food particles, grease, and debris can accumulate in the filter, leading to reduced cleaning efficiency, unpleasant odors, or even potential damage to the appliance. This comprehensive guide will walk you through the process of cleaning your KitchenAid dishwasher filter step-by-step, provide additional maintenance tips, and address common questions to help you keep your dishwasher in top shape.
#### Why Cleaning the Filter Matters
The filter in your KitchenAid dishwasher serves a vital purpose: it traps food particles, debris, and other impurities to prevent them from clogging the drain or being redistributed onto your dishes during the wash cycle. As explained by Sears Home Services, “A clogged filter impairs the efficiency of your dishwasher. It restricts water flow, making it challenging for the dishwasher to clean your dishes thoroughly” [(( Sears Home Services ))]. Left unchecked, a dirty filter can overwork the appliance, increase energy consumption, and even lead to costly repairs. Regular cleaning ensures smooth operation, sparkling dishes, and a longer lifespan for your dishwasher.
#### Step-by-Step Guide to Cleaning the KitchenAid Dishwasher Filter
The cleaning process varies slightly depending on your KitchenAid dishwasher model, but most feature a two-part filter system: an upper filter assembly and a lower filter. Below is a detailed guide based on recommendations from KitchenAid’s official product help resources and other authoritative sources.
##### Step 1: Prepare Your Dishwasher
Before you begin, ensure the dishwasher is empty and turned off for safety. Open the door and remove the bottom dish rack to access the filter, which is typically located at the bottom center or in a back corner of the dishwasher tub. “Remove the bottom dish rack from the dishwasher,” advises the KitchenAid Product Help site, as this exposes the filter area for easy access.
##### Step 2: Locate and Remove the Filter
Most KitchenAid dishwashers have a triple filter system consisting of an upper filter assembly and a lower filter. According to KitchenAid, “The upper filter assembly keeps oversized items and foreign objects, along with very fine food particles, out of the pump. The lower filter keeps food from being recirculated onto your dishes” [(( KitchenAid Product Help ))]. To remove them:
– **Upper Filter Assembly**: Gently turn the upper filter a quarter turn counterclockwise and lift it out. It may be cylindrical, about 4 inches in diameter, depending on your model.
– **Lower Filter**: Lightly grasp the lower filter, lift it slightly, and pull it forward to remove it. Some older models may not have a removable lower filter, in which case you’ll clean it in place after removing the upper part.
Handle the filters carefully to avoid damage, as a compromised filter can affect performance.
##### Step 3: Clean the Filters
Once removed, take the filters to your sink for cleaning. KitchenAid recommends, “Rinse filter under running water until most soils are removed. If you have hard-to-remove soils or calcium deposits from hard water, a soft brush may be required.” Here’s how to do it:
– Rinse both the upper and lower filters under warm running water to dislodge loose debris.
– For stubborn residue, soak the filters in warm, soapy water with a mild dish detergent for a few minutes to dissolve grease. Flamingo Appliance Service suggests, “Dish soap can be used, but make sure to thoroughly rinse it off as you don’t want additional detergent in the dishwasher” to avoid excess suds.
– Use a soft toothbrush or sponge to gently scrub away stuck-on food particles or calcium buildup. Avoid wire brushes or scouring pads, as they can damage the filter’s mesh or plastic components.
– For hard water deposits, distilled white vinegar can be a game-changer. “Either pour white vinegar over the filter or place the filter in a bowl of white vinegar and leave to soak for 30 minutes to an hour,” advises Flamingo Appliance Service.
Rinse thoroughly after cleaning to ensure no soap or vinegar remains.
##### Step 4: Clean the Filter Area
While the filters are out, inspect the area where they sit. Grime and excess water can accumulate here, especially if maintenance has been neglected. Use a sponge or cloth to wipe away any residue and soak up standing water. This step ensures a clean environment when you reinstall the filters.
##### Step 5: Reinstall the Filters
Proper reinstallation is crucial to avoid damage during operation. KitchenAid instructs, “Place the lower filter under the locating tabs at the bottom of the dishwasher, so the round opening for the upper filter assembly lines up with the circular opening in the bottom of the tub.” Then:
– Insert the upper filter into the opening in the lower filter.
– Rotate it clockwise until it drops into place and locks. “If the filter is not fully seated (still turns freely), continue to turn the filter clockwise until it drops and locks into place,” notes KitchenAid. The arrows on the upper and lower filters don’t need to align perfectly, as long as the filter is secure.
– Verify that both filters are firmly in place and cannot move freely before sliding the bottom rack back in.
KitchenAid warns, “To avoid damage to the dishwasher, do not operate your dishwasher without the filters properly installed.”
#### Additional Maintenance Tips
Cleaning the filter is just one part of keeping your KitchenAid dishwasher in peak condition. Here are some expert-backed tips to enhance its performance and longevity:
– **Frequency of Cleaning**: “We suggest cleaning the filter at least once a month, or more often if you notice signs of clogging or reduced performance,” recommends Sears Home Services. If you have hard water or use the dishwasher heavily, monthly cleaning may be necessary.
– **Prevent Debris Buildup**: Scrape excess food off dishes before loading them. This reduces the strain on the filter and improves cleaning results.
– **Run a Cleaning Cycle**: Use a dishwasher cleaner like Affresh tablets or a cup of white vinegar on the top rack once a month to tackle mineral buildup and odors in hard-to-reach areas. Cody’s Appliance Repair notes, “Run hot water from the tap before starting your dishwasher” to ensure optimal cleaning performance.
– **Check for Damage**: Inspect the filter for cracks or wear during cleaning. If damaged, replace it promptly to maintain efficiency. Replacement parts are available on KitchenAid’s official website.
#### Special Cases: Maintenance-Free Filters
Some newer KitchenAid models feature the Advanced Clean Water Wash System with a maintenance-free filter. “This system only requires you to occasionally empty a cup that prevents foreign objects from entering the dishwasher pump if it fills with particles or objects,” explains KitchenAid. If your dishwasher has this feature, check the cup periodically and empty it as needed—no regular filter cleaning required.
#### Troubleshooting Common Issues
If your dishwasher isn’t cleaning well or draining properly, a dirty filter might be the culprit. Flamingo Appliance Service lists signs that it’s time to clean the filter:
– Excessive debris or grease on the upper filter assembly.
– Dishes feeling gritty after washing.
– Poor drainage or standing water at the bottom.
For older models, accessing the filter might involve additional steps, such as removing screws with a Torx bit, as noted by Kitchen Seer. Consult your dishwasher’s manual for model-specific instructions.
