The humble dishwasher is one of the modern world’s greatest marvels. Clean dishes without having to do basically anything? Sign us up. However, these appliances involve one crucial maintenance task that often flies under the radar.
Many newer dishwashers include filters that keep food debris from entering your water lines, but these filters also require regular cleaning. Failing to do so can lead to costly dishwasher repairs and icky post-wash dishes. Luckily, this cleaning process is DIY-friendly and takes just a few minutes.
Prepping to Clean a Dishwasher Filter
The most important thing to do before cleaning your dishwasher’s filter is, well, figuring out if the filter requires cleaning. Many older models include self-cleaning filters of various types. As a general rule of thumb, newer dishwashers manufactured in the past decade include filters that require manual cleaning. Manufacturers made the switch away from self-cleaning filters in 2010 as part of an industry redesign to make dishwashers quieter during use.
If you are unsure, check the instructions that accompanied the dishwasher when you purchased it. Still not sure? Perform a quick web search with your exact make and model.
Find the Filter

A dishwasher filter location rests on the bottom of the interior of the unit, directly underneath the spray arms. As a note, self-cleaning filters feature a circular plastic grid or a series of holes covering the exterior. Those that need manual cleaning are round and resemble the filters included with water pitches.
Remove the Bottom Rack and Filter

Start by removing the bottom dish rack to provide an unrestricted view of the filter casing. The vast majority of these filters are round with arrows indicating which way to turn the cylinder to remove it. If so, simply twist and pull to remove the filter.
A small minority of filters include both a cylinder removed via twisting and a secondary flat filter below this cylinder. Flat filters do not lock in place, so grab the hole in the middle and simply pull it out. For more unusual designs, consult the instructions or contact the manufacturer directly.
Clean the Area Surrounding the Filter

If you spot any large chunks of debris, remove them and toss them in the trash. This area is highly susceptible to debris not just because of its proximity to the filter, but because it is located at the bottom of the dishwasher.

Once rinsed, gently scrub the exterior of the filter with a soft cloth or brush to remove accumulated debris and complete the cleaning process. Once you’re done scrubbing, give it another quick rinse. As a warning, avoid wire brushes and scrubby pads here as they are harsh and could damage the filter.
Reinsert the Filter
Now that the filter is all fresh and sparkly, reinsert the component back inside the dishwasher. Locate the relevant compartment and follow the steps in reverse to reattach the filter. There is no need to allow the filter to dry, as these dishwasher filters deal with plenty of liquids with each and every wash. Once reattached, load the dishwasher and marvel at the results.
DIY Dishwasher Cleaning vs. Hiring a Pro
This job is DIY-friendly, requiring just rags, brushes, and hot water. Buying a new dishwasher costs $400, on average, and performing regular maintenance like this can help you put off that expense as long as possible. However, if you already have a pro looking at the dishwasher while conducting repairs, they may clean the filter as part of a troubleshooting routine or just as a courtesy.
Additionally, if you regularly hire a local house cleaning service, you can ask them to add cleaning your dishwasher filter to their deep-cleaning routine.
This depends on how often you use the dishwasher and how clean the dishes are before entering the appliance. If you run the dishwasher daily and don’t scrape or rinse items before loading, for instance, clean the filter every month. If you use it just once or twice a week and rinse dishes before loading, clean the filter every three to six months. Jot this simple maintenance task on a calendar and stick to the schedule.
Yes, if your filter is damaged or simply too debris-filled to be of use, replace it with a new component. Check the instruction manual that accompanied the dishwasher for information as to the specific part. There are many online marketplaces that sell these parts, but perform due diligence to ensure you buy the right one.
