There’s nothing more frustrating than expecting your laundry to come out fresh and clean, only to be met with a musty, sour odor. You’ve used detergent, maybe even added fabric softener, and still—the unpleasant smell persists. If this scenario sounds familiar, there may be a simple but often overlooked reason: a clogged filter in your washing machine.
Every washing machine, whether front-loading or top-loading, has a filter. This component is designed to catch lint, hair, detergent residue, and other small debris from the wash water. Over time, this debris builds up, and if the filter isn’t cleaned regularly, it can block proper drainage, lead to standing water in the machine, and even cause mold or mildew to grow inside the washer.
The result? Your clean clothes absorb these unpleasant odors, and the entire laundry process feels like a waste of time and effort.
When a washing machine filter is clogged, it prevents the proper flow of water during the drain and spin cycles. This can leave behind excess moisture in the drum, hoses, and internal parts of the washer. Standing water becomes a breeding ground for bacteria and mold. Add warm, damp conditions into the mix, and you’ve got the perfect environment for that all-too-common musty smell.
Not only can this impact your laundry’s freshness, but it can also affect your health and the performance of your washing machine. Breathing in mold spores regularly isn’t good for anyone, especially those with allergies or respiratory issues.
A musty smell isn’t the only symptom of a clogged filter. Here are a few other signs that could indicate an issue:
If you’re noticing any combination of these signs, it’s time to check the filter.
Manufacturers typically recommend checking and cleaning the washing machine filter every 1 to 3 months, depending on how often you do laundry and the type of items you’re washing. If you regularly wash pet blankets, heavy towels, or clothes with a lot of lint, you might need to clean it more frequently.
Unfortunately, many homeowners aren’t aware that the filter exists—or that it needs maintenance—until a problem arises.
Some homeowners are comfortable checking and cleaning the filter on their own. If you decide to go this route, always unplug the machine first and have towels ready for any water that may spill out. Your machine’s user manual will have specific instructions on how to access the filter, which is usually located at the bottom front panel of the washer.
However, if your machine is showing signs of deeper issues—such as drainage problems, persistent odors, or unusual noises—it’s best to call a professional. Attempting repairs without proper knowledge can lead to further damage and higher repair costs down the line.
Neglecting a clogged filter doesn’t just affect your laundry. Over time, this buildup can strain your machine’s motor and internal systems, reducing its efficiency and lifespan. You could end up needing more extensive repairs—or even a new washer—sooner than expected.
