How to Clean a Dishwasher Filter – Ka Pai Plumbing’s Easy Guide
If your dishwasher has been leaving dishes less than sparkling, taking longer to run, or giving off an unpleasant smell, there’s a good chance the filter needs a clean.
It’s a simple job that can make a big difference - and you don’t need to be a plumber to do it. At Ka Pai Plumbing, we love helping our Wellington community with all kinds of plumbing jobs, big or small. Here’s our step-by-step guide to how to clean a dishwasher filter and get your appliance running smoothly again.
Why Your Dishwasher Filter Matters
Your dishwasher filter traps food particles and debris, stopping them from recirculating onto your clean dishes. But over time, that trapped food can build up, leading to:
Clogs that prevent proper drainage
Bad smells
Reduced cleaning performance
Extra strain on your dishwasher’s pump
Cleaning it regularly not only helps your dishwasher last longer but also keeps your dishes truly clean.
Step-by-Step: How to Clean a Dishwasher Filter
1. Turn off and empty your dishwasher
Safety first - make sure the dishwasher is off and cool. Remove any dishes.
2. Find the filter
In most dishwashers, the filter is located at the bottom, beneath the lower spray arm. You may need to remove the bottom rack to get a clear view.
3. Remove the filter
Most filters twist out counterclockwise. Some models have two parts - a cylindrical filter and a flat mesh screen.
4. Rinse under warm water
Hold the filter under warm running water. Use a soft brush or old toothbrush to gently scrub away stuck-on debris. Avoid harsh scrubbing to prevent damage.
5. Soak for stubborn grime
If there’s greasy buildup, soak the filter in warm soapy water for 10-15 minutes, then rinse.
6. Clean the filter housing
Before putting the filter back, wipe inside the housing with a damp cloth to remove any hidden debris.
7. Replace the filter
Twist the filter back in until it locks into place. Make sure it’s secure - running the dishwasher without the filter installed properly can damage it.

How to get rid of smell in dishwasher
A smelly dishwasher is often caused by trapped food particles. Clean the filter, wipe down the door seals, and run an empty cycle with vinegar and baking soda:
Place a cup of white vinegar on the top rack and run a hot cycle.
Sprinkle a cup of baking soda on the bottom and run a short cycle.
This natural combo deodorises and helps break down buildup.Can I use vinegar and baking soda together?
Yes - just don’t put them in at the same time in the same compartment, or you’ll have a fizzy overflow before the cycle even starts. Use vinegar first, then baking soda.
