How to Clean the Dishwasher Filter
A dishwasher is a lifesaver in the kitchen, but like any appliance, it needs regular care to perform at its best. One of the most overlooked yet essential maintenance tasks is cleaning the dishwasher filter. A clogged or dirty filter can lead to poor cleaning results, funky odors, and even costly repairs. In this guide, we’ll walk you through the step-by-step process of cleaning your dishwasher filter, share expert tips, and dive into related maintenance advice to keep your machine running smoothly.
Why Cleaning the Dishwasher Filter Matters
Before we get into the how-to, let’s understand why this task is so important. The filter in your dishwasher traps food particles, grease, and debris to prevent them from clogging the drain or redepositing onto your dishes. Over time, this buildup can reduce efficiency, harbor bacteria, and cause unpleasant smells. According to Whirlpool, “Regularly cleaning the filter improves dishwasher performance and ensures your dishes come out spotless every time” [(( Whirlpool ))]. Neglecting it might even void your warranty on some models, so let’s get started!
Step-by-Step Guide to Cleaning Your Dishwasher Filter
Step 1: Locate the Filter
The first thing you need to do is find the filter. Most dishwashers have it at the bottom of the tub, either under the lower spray arm or in a cylindrical housing near the base. Check your owner’s manual if you’re unsure—every model is a bit different. For example, Bosch dishwashers often have a two-part system with a flat filter and a cylindrical one beneath it.
Step 2: Turn Off the Dishwasher
Safety first! Unplug the dishwasher or switch it off at the circuit breaker to avoid any accidental starts while you’re working. This step is especially crucial if your filter requires tools to remove.
Step 3: Remove the Filter
Gently twist or pull the filter out, depending on your model. The Spruce advises, “Look for a twist-off cap or a latch—most filters are designed to come out easily without forcing it” [(( The Spruce ))]. If it’s stuck, don’t yank—check for screws or clips and refer to your manual.
Step 4: Rinse the Filter
Take the filter to your sink and rinse it under warm running water. Use a soft brush (like an old toothbrush) to scrub away stubborn bits of food or grease. Avoid harsh chemicals unless specified by the manufacturer—plain water and a mild dish soap usually do the trick. For caked-on grime, Bob Vila suggests soaking it in warm, soapy water for 10 minutes before scrubbing [(( Bob Vila ))].
Step 5: Inspect and Clean the Filter Housing
While the filter is out, peek into the housing area. Wipe away any debris with a damp cloth or sponge. This spot can get slimy, so a quick clean prevents buildup from affecting the filter’s performance later.
Step 6: Reinstall the Filter
Once everything’s clean and dry, pop the filter back into place. Make sure it’s secure—twist or lock it as needed. A loose filter can let debris sneak through, undoing all your hard work.
Step 7: Run a Test Cycle
Run a short rinse cycle with an empty dishwasher to ensure everything’s working correctly. This also flushes out any leftover particles you might have missed.
How Often Should You Clean the Filter?
Experts recommend cleaning your dishwasher filter every month if you use it daily. However, if you rinse your dishes thoroughly before loading, you might stretch it to every two months. GE Appliances notes, “Check your filter after every 10-15 cycles if you notice residue on dishes—it’s a sign it’s time to clean” [(( GE Appliances ))]. Adjust based on your household’s habits!
Extra Tips for Dishwasher Filter Maintenance
- Vinegar Hack: For a deep clean, soak the filter in white vinegar for 15-20 minutes to dissolve mineral deposits or grease. Rinse thoroughly afterward.
- Check for Damage: Inspect the filter for cracks or tears while cleaning. A damaged filter should be replaced—check your manufacturer’s website for the right part number.
- Pre-Rinse Dishes: Scraping food off plates before loading reduces the filter’s workload, extending its life.
Beyond the Filter: Holistic Dishwasher Care
Cleaning the filter is just one piece of the puzzle. To keep your dishwasher in top shape, consider these additional steps:
- Wipe the Door Gasket: Use a damp cloth with vinegar to clean the rubber seal around the door—it’s a hotspot for mold.
- Run a Cleaning Cycle: Once a month, run an empty cycle with a dishwasher cleaner (like Affresh) or a cup of vinegar on the top rack to descale the interior.
- Clear the Spray Arms: Remove and rinse the spray arms if water flow seems weak—clogged holes can mimic a dirty filter’s symptoms.
Common Mistakes to Avoid
- Using Bleach: Unless your manual says it’s safe, skip bleach—it can damage stainless steel or rubber parts.
- Forgetting to Dry: Reinstalling a wet filter can trap moisture and encourage mold growth.
- Ignoring Odors: A smelly dishwasher often points to a filthy filter—don’t mask it with air fresheners; clean it instead.
FAQ: Your Dishwasher Filter Questions Answered
Q: How do I know if my dishwasher has a filter?
A: Most modern dishwashers have a manual filter you can remove and clean. Check your manual or look at the bottom of the tub. Some older or budget models have self-cleaning filters, but these still benefit from occasional checks.
Q: Can I run my dishwasher without the filter?
A: No! The filter protects the pump and drain from clogs. Running it without one risks damage and voids warranties on many models.
Q: Why does my filter keep clogging so fast?
A: You might be loading heavily soiled dishes without scraping them first. Hard water or greasy foods can also speed up buildup—try a descaling agent monthly.
Q: Is it okay to put the filter in the dishwasher to clean it?
A: Nope, that’s a bad idea. The heat and detergent can warp or degrade it. Stick to hand-washing.
Q: How long does a dishwasher filter last?
A: With proper care, it can last the life of your dishwasher. Replace it only if it’s damaged—otherwise, cleaning keeps it functional.
