How to Clean a Dishwasher Filter
A dirty dishwasher filter is one of the most common reasons dishes come out smelling bad, looking cloudy or not properly cleaned. The filter collects food particles and grease over time and needs regular cleaning. The good news: it takes about 5 minutes.
How Often Should You Clean the Filter?
Once a month is the recommended frequency for a household that runs the dishwasher daily. If you pre-rinse dishes before loading, every 6–8 weeks is sufficient. If you notice dishes coming out with an odour or feel gritty, clean the filter immediately regardless of when you last did it.
How to Find the Filter
The filter is located at the bottom of the dishwasher, typically under the lower spray arm. It is usually a cylindrical component that sits inside a flat mesh screen. Remove the lower rack to access it.
Step-by-Step: Cleaning the Dishwasher Filter
Step 1: Turn Off the Dishwasher
Make sure the dishwasher is not running and is cool to the touch before you start.
Step 2: Remove the Lower Rack
Pull out the lower dish rack and set it aside.
Step 3: Twist Out the Cylindrical Filter
Most filters twist counter-clockwise to unlock. Turn it about 90 degrees and lift it straight up. It should come out easily. Some models have a two-part filter: the cylindrical filter lifts out first, then the flat mesh underneath lifts out separately.
Step 4: Rinse Under Running Water
Hold the filter under warm running water and rinse away loose food particles. Use a soft brush (an old toothbrush works perfectly) to scrub the mesh surface. Pay attention to the inside of the cylindrical section where grease can accumulate.
Step 5: Soak in Warm Soapy Water
For a heavily soiled filter, soak in warm water with a small amount of dish soap for 10–15 minutes, then scrub and rinse. Avoid steel wool or abrasive pads, which can damage the mesh.
Step 6: Wipe the Filter Housing
While the filter is out, wipe around the filter housing with a damp cloth to remove any debris that has accumulated in the base of the dishwasher. Check the drain area for any large food pieces.
Step 7: Reinstall the Filter
Place the flat mesh screen back first (if your model has one), then insert the cylindrical filter and twist clockwise until it locks. It should sit flush with the base of the dishwasher with no wobble.
Step 8: Run a Cleaning Cycle
Place a dishwasher cleaning tablet or a cup of white vinegar in the bottom of the dishwasher and run a hot cycle with no dishes. This cleans the spray arms, internal walls and door seal.

- Dishes feel gritty or look dirty after washing
- Unusual odour from inside the dishwasher when you open it
- Spray arms appear blocked (remove and clean the holes with a toothpick)
