Most Whirlpool dishwashers feature a filter system, typically comprising an upper filter assembly and a lower filter, often part of a triple filter system.
This filter traps food particles, debris, and other residues, preventing clogs and maintaining efficient operation.
Over time, however, it can accumulate soils, calcium deposits, and grime, leading to reduced cleaning performance, unpleasant smells, or gritty dishes.
Regular cleaning is crucial, especially if you do not rinse dishes before loading, as recommended by Whirlpool guidelines.
When to Clean the Filter
You should consider cleaning the filter under the following conditions:
- Visible objects or soils are present on the upper filter assembly.
- There is a noticeable degradation in cleaning performance, such as dishes with remaining food residues.
- Dishes feel gritty or have a film after washing.
- The dishwasher emits odours, which can indicate trapped debris.
The frequency of cleaning varies based on usage. Whirlpool suggests checking your dishwasher’s manual for specific recommendations, but general guidelines include cleaning every few months.
For comparison, Bosch recommends 3–6 times per year if rinsing dishes beforehand and 4–12 times per year if not, while Miele notifies users every 50 washes. Given these variations, it’s advisable to consult your model’s manual for the most accurate schedule.
Supplies and Tools Needed
To clean the filter effectively, gather the following:
- Warm water and a sink or basin for rinsing.
- A soft brush, sponge, or old toothbrush for scrubbing tough spots.
- Dish soap, if needed for stubborn deposits.
Avoid using abrasive tools like wire brushes or scouring pads, as they can damage the filter and affect its functionality.
How to Clean a Whirlpool Dishwasher Filter: Step-by-Step Cleaning Process
The process is typically quick, taking just a few minutes, and can be broken down into three main steps:
Step 1: Locate and Remove the Filter
- Begin by removing the lower dish rack to expose the bottom of the dishwasher. This provides clear access to the filter area.
- The filter is usually located at the bottom centre of the dishwasher tub, often under the bottom spray arm or in one of the back corners. Check your manual for model-specific locations.
- For filters with upper and lower parts (common in Whirlpool models):
- Turn the upper filter assembly counterclockwise by a quarter turn and lift it out. This is a simple twist-and-lift motion.
- Grasp the lower filter in the circular opening, lift it slightly, and pull it forward to remove it from the tub.
This step ensures you have full access to the filter for cleaning, and it’s important to handle the components carefully to avoid damage.
Step 2: Clean the Filter
- Rinse the filter under running warm water to remove loose soils, food particles, and debris. This initial rinse helps dislodge most residues.
- For tougher deposits, such as calcium buildup or hard-to-remove food particles, use a soft brush (like a sponge or old toothbrush) and apply dish soap if necessary. Gently scrub to ensure all areas are clean, paying attention to smaller crevices where debris might hide.
- Avoid using abrasive materials like wire brushes or scouring pads, as they can scratch or damage the filter, potentially leading to leaks or reduced efficiency.
This step is crucial for restoring the filter’s functionality and ensuring it can trap debris effectively during future cycles.
Step 3: Reinstall the Filter
- Place the lower filter back into the dishwasher tub, ensuring it is positioned under the locating tabs and aligned with the circular opening in the tub. This ensures proper fit and function.
- Insert the upper filter assembly into the lower filter’s circular opening, aligning it for installation.
- Rotate the upper filter clockwise until it drops and locks into place. Ensure it is securely locked by checking that it does not freely turn. A loose filter can damage the dishwasher during operation.
- Note: The arrow on the upper filter assembly does not need to align perfectly with the arrow on the lower filter, as long as the filter is properly locked and secure.
This step is critical to prevent operational issues, such as water leaks or reduced cleaning performance, so double-check the lock before running the dishwasher.
Additional Maintenance Tips
- Inspect for Damage: After cleaning, inspect the filter for signs of wear or damage. If it is cracked, warped, or excessively worn, replace it immediately to avoid further issues. You can find replacement parts at Whirlpool’s parts website.
- Overall Dishwasher Cleaning: For a fresh-smelling dishwasher, consider running a cleaning cycle with vinegar and baking soda. Remove any dishes first, pour 2 cups (500 mL) of white vinegar into a dishwasher-safe container, place it on the lower rack, and run a normal cycle with the heat dry option turned off. After, sprinkle 1 cup of baking soda on the bottom and run a hot water cycle. This complements filter cleaning and addresses odours.
- Check for Standing Water: If you notice standing water in the filter well after cleaning, this is normal due to the dishwasher’s design to prevent siphoning. However, excessive water or gunk may indicate a drainage issue, which you can troubleshoot by ensuring the filter is clean and checking for clogs.
Troubleshooting and User Insights
Some users on platforms like Reddit have reported difficulty locating the filter, especially on older or less common models.
For instance, one user found their Whirlpool dishwasher lacked a removable filter, suggesting not all models have cleanable filters.
Always refer to your manual to confirm if your model has a filter and how to access it. If you are unsure, don’t hesitate to get in touch with Whirlpool support for assistance.
Additionally, if cleaning doesn’t resolve issues like poor cleaning performance or odours, consider checking other components, such as the spray arms or drain, for blockages.
