The Best Method for Cleaning Your Dishwasher's Filter, According to Experts

Have you ever waited patiently for your dishwasher to ding, only to open the door and find cloudy glassware or be hit with a mildew smell? Your dishwasher filter might be the culprit. Over time, food particles, grease, and soap scum can accumulate in this part of the machine, affecting your dishwasher’s performance and leaving you with less-than-perfect results. Fortunately, learning how to clean your dishwasher filter is easier than you may think. 

Whether you’re dealing with dull dishes or are looking for maintenance tips for keeping your dishwasher running smoothly for years to come, we’ve got you covered with expert advice, step-by-step instructions, and how regularly to tackle the task of caring for the filter. With a few simple steps, you’ll be well on your way to a nearly new dishwasher again.

Here's how to clean your dishwasher filter, according to a cleaning professional and a home appliance specialist.

How Often to Clean Your Dishwasher Filter

Your dishwasher filter should be cleaned regularly to maintain efficacy. But just how regularly? According to cleaning professional Melissa Maker, this depends on how often you run your appliance. At a minimum, the task should be undertaken every one to two months.

“Even if you clean your dishwasher filter regularly, you might need to clean it more often if you’re using it more frequently,” agrees Jeff Sweet, an appliance specialist. This applies to those with large families who may be running their dishwasher daily, or during the holidays when the kitchen typically sees an increase in entertaining. A dishwasher cleaning tablet can help maintain the filter between cleanings, adds Maker.

Signs That You Should Clean Your Dishwasher Filter

Keep an eye out for a few signs that your dishwasher filter is due for a deep clean outside of its regularly scheduled maintenance. According to Sweet, the biggest red flags include unpleasant or mildew-like odors coming from the dishwasher and dishes that come out dirty, spotty, or cloudy after a cycle.

Another clue? Water pooling at the bottom of your dishwasher. As Maker points out, this is a common indication that the filter may be clogged and needs cleaning.

2. Remove the lower rack of the dishwasher to access the filter.
3. Consulting your model's manual for specific removal instructions, take out the filter. (This usually involves turning it counterclockwise.) 
4. Rinse the filter under warm water to remove loose debris.
5. In a sink or basin, mix warm water with about a teaspoon of dish soap.
6. Add the filter to the soapy solution and let soak for 10-15 minutes.
7. Using a soft scrub brush or toothbrush, gently scrub the filter to dislodge any remaining particles.
8. Rinse thoroughly to ensure all soap and debris are removed.
9. Wipe the filter dry with a microfiber cloth.
10. Reinstall the filter and lower rack into the dishwasher.

How to Maintain Your Dishwasher Filter

To keep your dishwasher filter cleaner for longer, there are a few simple habits to adopt. First, Maker suggests ensuring dishes are, if not rinsed, at least scraped clean of large food particles before loading them in. This small step can go a long way in keeping food debris from clogging up your filter.

You should also avoid overloading your dishwasher. Giving your dishes a little breathing room helps everything get cleaned more effectively. Also, opt for a high-quality dishwashing detergent. A good detergent is better at breaking down food particles and leaves less residue behind. It's a worthy investment!
