Regular upkeep of your home's appliances is crucial for maintaining their performance, and your dishwasher is no different. The machine's filter is just as important as the wash tub. Thankfully, the process is simple, with just a few quick steps. Below, we dive into how to clean a dishwasher filter so your dinnerware and other kitchen essentials come out table-ready every time.

Getting Started

Keeping your dishwasher filter well-maintained is essential to the dishwasher's performance; proper, regular care helps the appliance clean its best. Skipping routine cleaning sessions leads to food build-up. In turn, this can cause poor wash and rinse cycles. And that often means your dishes come out looking duller and even a little spotty. But don't panic; the process of understanding how to clean a dishwasher filter isn’t difficult. With the steps listed below, you’ll have the appliance’s filter clean and ready to work.

Understanding Your Dishwasher's Filter Type

Before learning how to clean a dishwasher filter, it's important to know which kind you have. Dishwasher filters come in two varieties: self-cleaning and manual. The former grinds up lingering food via a garbage-disposal system. Then, debris is sent down the drain effortlessly.

Meanwhile, manual filters use a fine mesh system to trap and break down food grime. Just as the name implies, you'll need to step in and manually clean the filter every now and then, which is covered in the steps below.

Step One: Finding the Filter

For most dishwashers, the filter is located beneath the lower rack. You can also find it near the back corner of the basin or near the bottom spray arm. If your dishwasher has a two-part triple filter system, then you'll also need to remove the upper filter, which prevents larger particles from getting into the pump. The lower one carefully traps finer residue from recirculating during the chosen cycle. For bottom placements, simply grab and remove the filter. On the top, you'll need to twist clockwise and slowly loosen it.

Step Two: Clean Away Any Grime and Lingering Food

Once removed, it's finally time to learn how to clean a dishwasher filter. Set the filter(s) into the sink and thoroughly rinse them with warm water. This will wash away larger food and grime from the mesh. You can let them soak for five minutes before rinsing to loosen more stubborn residue.

Occasionally, you may be dealing with calcium deposits, which are more difficult to remove. In this case, use a small, soft-bristled brush to carefully scrub the mesh. You'll want to be extra careful to avoid damaging the filter. We recommend using a toothbrush or even a sponge.

Step Three: Return the Filter to the Appliance

Once the mesh has been cleaned, it's time to return the filter to its original position. If you've got two filters, then you'll want to reinstall the bottom one first. Be sure it's placed under the tabs and fully reinserted. Then, align the upper filter with the filter and turn it until it's secure. It should twist easily. If it doesn’t, you may need to realign the filter. For both, you'll know they're completely installed when you can’t turn them anymore; you don't want to risk one coming loose during the next dishwashing cycle. For more guidance, take a look at your dishwasher's user manual. Brands often include specific directions on how to properly clean the dishwasher's filter.

How Often Should You Clean a Dishwasher Filter?

Knowing how to clean a dishwasher filter is only half the battle. It’s also important to know how often the steps above need to be completed. Cleaning frequency depends on several factors, including the number of loads per week and whether you rinse/scape dishes beforehand. However, there are some clear indications that the filter needs to be cleaned. For example, keep an eye out for visible debris. And if you start to notice lingering residue on your dishes, or if they feel a little gritty afterward, then it’s time to clean the filter
