Dishwasher Filter Care: What You Can Clean—and When to Call a Technician
Learn how to identify a removable dishwasher filter, clean it safely, and recognize when a pump problem needs professional service.
Check the filter type for your model
A dishwasher may have a filter that needs manual cleaning or a self-cleaning system. Find the model number and read its instructions before removing anything. The location and locking arrangement vary; do not assume the same assembly is fitted to every appliance.
When cleaning may help
Visible food residue, gritty dishes, an unpleasant smell or declining cleaning performance are reasons to inspect a user-removable filter. These symptoms do not establish that the pump has failed. Choose the cleaning interval in the model instructions rather than a universal schedule.
Clean and reinstall the removable filter
Stop the appliance and follow the manual’s safety and removal instructions. Allow hot surfaces and water to cool. Rinse the removable filter under running water; use a soft brush for stubborn residue. Avoid wire brushes, abrasive pads and harsh scrubbing. Reinstall every filter part in its proper position and check that it locks as instructed. Do not run the dishwasher with its filter missing or incorrectly fitted.
When to use service
Filter cleaning is routine maintenance, not a method for diagnosing internal electrical or pump faults. If the filter cannot be removed as shown in the manual, is damaged, will not lock, or the problem persists, contact the manufacturer or qualified service. Keep the full model number, any displayed code and a record of the checks you completed.
Frequently asked questions
Can I use a wire brush?
