Things to Do When Cleaning a Dishwasher Filter
Maintaining a clean dishwasher filter is essential for peak performance and preventing unpleasant odors in your appliance.
A well-maintained filter guarantees proper water drainage, better cleaning results, and extends the lifespan of your dishwasher by preventing debris from clogging the system and potentially damaging internal components.
- Remove bottom rack – Clear the dishwasher's bottom rack to easily access the filter assembly located in the tub's base.
- Locate and remove filter – Twist the filter counter-clockwise to release it, then lift it straight up.
- Separate filter components – If applicable, separate the upper and lower filter assemblies for thorough cleaning.
- Rinse under water – Use warm running water to remove loose debris and food particles.
- Brush and clean – Scrub the filter with a soft brush and dish soap to remove stubborn residue.
- Soak if needed – Place filter in hot, soapy water for 10-15 minutes to loosen tough buildup.
- Rinse thoroughly – Verify all soap residue is completely rinsed away.
- Inspect filter – Check for damage or wear before reinstalling.
- Reinstall properly – Align and twist clockwise until the filter secures firmly in place.
- Schedule maintenance – Mark calendar for regular cleaning every 1-3 months.
Things to Avoid When Cleaning a Dishwasher Filter
Maintaining your dishwasher filter requires careful attention to proper cleaning techniques to guarantee its longevity and effectiveness. While regular cleaning is essential, certain practices can damage the filter or compromise its functionality, potentially leading to costly repairs or the need for premature replacement.
- Wire brushes and scouring pads – These abrasive tools can create scratches and tears in the filter material, reducing its effectiveness and creating spaces where debris can accumulate.
- Direct application of cleaning solutions – Pouring cleaners into the dishwasher bottom can damage internal components; always use a container on the top rack.
- Irregular maintenance – Skipping routine filter cleaning allows buildup of food particles and grease, causing unpleasant odors and poor cleaning performance.
- Forceful handling – Aggressive attempts to remove stuck debris can crack or break the filter components, making proper reinstallation impossible.
- Harsh chemical cleaners – Non-dishwasher-specific cleaning products can corrode or deteriorate the filter material and surrounding parts.
