How to Clean a Dishwasher Filter: Step-by-Step Guide
A dirty dishwasher filter is one of the most common reasons dishes come out cloudy, smelly, or still dirty after a cycle. The good news: cleaning your dishwasher filter takes less than five minutes and should be done every month. Here's exactly how to do it.
Why the Filter Gets Dirty
Your dishwasher filter traps food particles, grease and debris during every wash cycle. Over time, this buildup can clog the filter, reducing water flow and leaving residue on your dishes. A blocked filter can also cause unpleasant odours inside the machine.
How Often Should You Clean the Filter?
For average household use (once per day), clean the filter every 2–4 weeks. If you run the dishwasher more frequently or wash heavily soiled pots and pans regularly, clean it every 2 weeks.
What You Need
- Running warm water
- An old soft toothbrush or nail brush
- Mild dish soap
- A towel or dish rack for drying
Step-by-Step: How to Remove and Clean Your Dishwasher Filter
Step 1: Empty the Dishwasher and Remove the Bottom Rack
Pull out the bottom rack completely and set it aside. You need clear access to the floor of the dishwasher tub.
Step 2: Locate the Filter
The filter is usually located at the bottom of the dishwasher tub, beneath the lower spray arm. It typically consists of two parts: a cylindrical fine mesh filter and a flat coarse filter underneath it.
Step 3: Twist and Remove
Most filters are removed by twisting anti-clockwise about a quarter turn, then lifting out. Consult your manual if the filter doesn't release easily — some models have a clip or latch.
Step 4: Rinse Under Running Water
Hold the filter under warm running water and rinse away loose debris. Avoid hot water as it can warp some plastic filters.
Step 5: Scrub with a Soft Brush
Use a soft toothbrush and a small amount of dish soap to gently scrub the mesh. Pay attention to any clogged holes in the fine mesh filter — these are the most important to clear.
Step 6: Rinse Again and Inspect
Rinse the filter thoroughly under running water until the water runs clear. Hold it up to the light to check the mesh holes are all clear.
Step 7: Reinstall the Filter
Align the filter and twist clockwise until it locks into place. It should sit flush with the floor of the tub. Replace the bottom rack.
Bonus: How to Deodorise Your Dishwasher
After cleaning the filter, run a short hot cycle with a cup of white vinegar in the bottom of the tub (no dishes, no detergent). This removes grease and neutralises odours throughout the machine. Finish with a sprinkle of baking soda on the floor of the tub and run another short cycle.
