Learn How to Clean Your Maytag Dishwasher Filter

Understanding Your Maytag Dishwasher Filter System

The filter system in your Maytag dishwasher plays a crucial role in keeping your dishes clean and preventing damage to the appliance. Most Maytag dishwashers contain two main filter components: the upper filter and the lower filter. The upper filter, sometimes called the upper spray arm filter, sits near the top of the tub and catches larger food particles. The lower filter, located at the bottom of the dishwasher, traps smaller particles and debris before they reach the pump and drainage system.

Understanding how these filters work together helps you maintain your dishwasher more effectively. Water circulates through your dishwasher during each cycle, and the filters prevent food particles from clogging the spray arms, pump, and drain lines. When food buildup accumulates in these filters, your dishwasher may not clean dishes properly, drain slowly, or produce unpleasant odors. According to Maytag's maintenance guidelines, regular filter inspection helps extend the lifespan of your dishwasher and prevents costly repairs.

The filter design varies slightly depending on your Maytag model. Some models feature a cylindrical filter design, while others use a flat-screen filter at the bottom. Your dishwasher manual will indicate which type you have. Knowing your specific model number, which typically appears on a sticker inside the door edge or on the side wall of the tub, allows you to identify the correct filter configuration for your machine.

Practical takeaway: Locate your dishwasher's model number and consult your user manual to understand your specific filter configuration. This information will help you clean your filters correctly and avoid damaging components.

When to Clean Your Dishwasher Filter

Most Maytag dishwashers benefit from filter cleaning on a monthly basis, though the frequency depends on how often you run your dishwasher and how much food debris typically remains on your dishes before loading. If you run your dishwasher daily or load heavily soiled dishes, you may need to clean filters more often. Conversely, if you run your dishwasher just a few times weekly with lightly soiled dishes, monthly cleaning may be sufficient.

Several warning signs indicate that your filters need attention before your regular schedule. If water pools at the bottom of your dishwasher during or after a cycle, the filter may be clogged. A musty or sour smell coming from your dishwasher suggests trapped food debris decomposing in the filter area. If your dishes don't come out clean despite using quality detergent, reduced water flow from clogged filters could be the cause. Unusual noises during the wash cycle, such as grinding or rattling sounds, may indicate debris caught in the filter or pump.

Seasonal considerations also affect filter maintenance needs. During summer months when fresh fruits and vegetables are more common, or during holiday seasons when you host meals with larger crowds, filter cleaning may be needed more frequently. Winter months with fewer entertaining occasions typically require less frequent cleaning.

Practical takeaway: Create a monthly filter-cleaning reminder on your phone or calendar. Mark it on the first of each month, then adjust the frequency based on whether you notice any performance issues with your dishwasher.

Preparing Your Dishwasher for Filter Cleaning

Before you access your dishwasher's filter, prepare the appliance properly to ensure safety and prevent water damage. First, turn off the power to your dishwasher. If it's connected to an outlet, unplug it. If it's hardwired into your home's electrical system, switch off the appropriate circuit breaker. Waiting several minutes after powering down ensures any remaining water in the heating elements cools to a safe temperature.

Next, open the dishwasher door and pull out the lower rack completely. This gives you full access to the bottom of the tub where the filters are located. Look at the bottom of your dishwasher's interior. You should see either a cylindrical filter assembly or a flat-screen filter, depending on your model. Some Maytag models have a filter guard—a protective cover that sits above the main filter. If yours has one, note how it sits before removal so you can reinstall it correctly.

Have paper towels or an old towel ready before you begin. Even though you'll be accessing dry filters, having absorbent material nearby prevents water spills from spreading across your kitchen floor. A small bowl or bucket placed under the filter area can catch any water that drips from the filter housing. If you notice standing water in the bottom of your dishwasher, use a turkey baster or small cup to remove it before accessing the filter.

Practical takeaway: Set up a dedicated workspace before starting. Lay down paper towels, gather your supplies, and ensure your dishwasher is completely powered down. This organized approach prevents mishaps and makes the cleaning process faster.

Steps for Removing and Cleaning Your Filter

Once your dishwasher is ready, locate the filter assembly at the bottom of the tub. For cylindrical filters, which are most common in Maytag models, grasp the filter firmly and twist it counterclockwise about a quarter turn until it releases. The filter should lift straight up and out of the housing. For flat-screen filters, look for a latch or release button on the sides of the filter frame. Press these buttons or latches and lift the filter straight up. Handle the filter carefully—the edges can be sharp.

Place the removed filter in your sink or over a trash can. Hold it under running warm water and use your fingers or a soft-bristled brush to gently remove visible food particles and debris. Rinse from the outside first, allowing water to flow through the filter material. Pay special attention to any caked-on residue. For stubborn buildup, soak the filter in warm water for 10 to 15 minutes before brushing again. Never use harsh scrubbing pads, wire brushes, or high-pressure water jets, as these can damage the filter mesh.

For more thorough cleaning, some owners use a mixture of warm water and a small amount of dish soap. Soak the filter for several minutes, then gently brush while submerged. Rinse thoroughly under warm running water until the water runs clear and no soapy residue remains. If your filter has a protective guard or cover, clean this component separately using the same gentle method. Examine the filter for any cracks, tears, or damaged areas. If you see damage, the filter needs replacement rather than continued use.

Practical takeaway: Use warm water and gentle brushing techniques. Keep a soft-bristled brush specifically for dishwasher maintenance to avoid accidentally damaging the delicate filter mesh during cleaning.

Cleaning the Filter Housing and Drain Area

While your filter is soaking or drying, take time to clean the filter housing and surrounding drain area. This often-overlooked step prevents debris from accumulating in areas where you can't easily access it. Look at the bottom of your dishwasher where the filter sits. You may notice a plastic housing or cup that holds the filter in place. Wipe the interior surfaces of this housing with a damp cloth or paper towel to remove any food particles or slime buildup.

Inspect the drain area at the very bottom of your dishwasher. A small drain opening, usually located near the back corner of the tub floor, allows water to exit the appliance. Check around this drain for debris. You can carefully use a straightened paperclip or pipe cleaner to gently probe the drain opening and remove any trapped particles. Be very gentle—you don't want to crack the plastic housing or damage the drain valve. Many clogs that prevent proper drainage start with small particles accumulating around the drain area.

The spray arm sockets—where the upper and lower spray arms connect to the water supply—also benefit from inspection. Look for any visible debris or mineral deposits. If you see buildup, use a damp cloth to wipe the socket areas. For mineral deposits from hard water, a cloth dampened with white vinegar can help dissolve the buildup. After cleaning with vinegar, rinse thoroughly with plain water to remove any vinegar residue.

Practical takeaway: Dedicate 5 to 10 minutes to cleaning the filter housing, drain area, and spray arm sockets while your filter dries. This additional cleaning prevents future clogs and improves overall dishwasher performance.
