Cleaning your dishwasher filter is essential for ensuring that your dishes come out sparkling clean and that your appliance operates efficiently. If you have ever noticed murky water pooling at the bottom of your dishwasher or found grit on your freshly washed glasses, a dirty filter could very well be to blame. Surprisingly, a clogged filter can not only impact the cleanliness of your dishes but also lead to costly repairs if left unchecked. In this post, we will guide you through the step-by-step process of removing, cleaning, and reinstalling your dishwasher filter while sharing maintenance tips to keep it operating at its best.
By the time you finish reading, you will have all the tools and knowledge necessary to keep your dishwasher filter clean and your dishes shining like new. Let’s dive in and ensure your dishwasher works as effectively as possible!
Dirty dishes, clogged drains, and a squeaky-clean finish all start with one simple habit: keeping your dishwasher filter clean. If you’ve ever opened the door to a murky bottom or noticed grit on your glasses, the culprit is often a starved, clogged filter. In this guide, you’ll find practical, model-spanning steps to remove, clean, and reinstall the filter, plus smart maintenance habits to keep buildup from returning.
The filter sits at the bottom of the tub and acts as a barrier to trap food particles before water is pumped through the spray arms and out the jets. If debris accumulates, drainage slows, cleaning performance drops, and the pump can struggle. Many dishwashers use a two-part filtration system—an Ultra Fine Filter and a Fine Filter—that both require attention to maintain peak performance.

Most guidelines suggest inspecting and cleaning the filter every one to four months, or more frequently if you have hard water or you routinely wash loads with heavy food soil. For households with heavy usage, visible debris, or mineral buildup, clean the filter more often to maintain peak performance.
Some dishwashers feature a two-part removable filtration system that must be cleaned separately. In these cases, the Ultra Fine Filter is removed first, then the Fine Filter, rinsed, and reassembled in reverse order. Always check your manufacturer’s guidance for exact steps to avoid damage.
While steps vary, most major brands outline similar processes:
If you’ve cleaned the filter but drainage remains slow or dishes still come out less-than-sparkling, check these areas as well:

Regular maintenance matters because a clean filter preserves drainage efficiency, prevents food particle buildup in the sump, and extends the life of the pump and motor. A systematic approach—removing, rinsing, reassembling, and then testing with an empty cycle—helps you spot issues before they become costly repairs. A practical maintenance cadence, adapted to your water hardness and load level, yields tangible results in energy and water use, scrub-free dishes, and longer appliance life.
