Filter Maintenance 101: The Ultimate Guide to Cleaning Your Dishwasher Filter

March 4, 2024 | Dishwashers

Your dishwasher is a true hero in your kitchen. It diligently tackles the aftermath of family dinners, dinner parties and a sink full of chaos with ease. In our ultimate guide to cleaning your dishwasher filter, we show you how a little maintenance can help your dishwasher churn out spotless dishes time and time again!

What does a dishwasher filter do?

The filter keeps the dishwasher working efficiently by catching and trapping leftover food and debris from dishes after washing.

Filters particles

The filter stops food particles and debris from going back into the dishwasher’s water system. This in turn helps prevent clogs and damage to the dishwasher’s pump and other parts.

Prevents clogging of drain

The filter stops food particles from getting into the dishwasher drain, lowering the chance of drain clogs. A clogged drain can cause water to back up in the dishwasher, leading to potential water damage.

Improves cleaning performance

A clean filter allows water to circulate and clean dishes effectively. A blocked filter may lead to dirty dishes, re-depositing food particles on plates, glasses, and utensils.

Protects dishwasher spray arm and pump

The filter protects the dishwasher’s pump and spray arm by capturing large particles. If these parts get clogged with debris, it can cause low water flow, ineffective cleaning, and possible damage to the appliance.

Controls odours

The filter also helps avoid the buildup of food residues that can create unpleasant odours in the dishwasher. Keeping the filter clean through regular maintenance ensures a fresh-smelling appliance.

Extends dishwasher life span

Taking care of the filter through proper maintenance contributes to the overall health and longevity of the dishwasher. The filter prevents damage to components and ensures your dishwasher works well.


Dishwasher do’s and don’ts

Before we get our hands dirty, let’s establish some ground rules – the do’s and don’ts of dishwasher filter maintenance!

Do’s

  • Regular check-ups: Make it a habit to inspect the filter at least once a month. This helps you catch any issues before they escalate.
  • Follow manufacturer guidelines: Every dishwasher is different. Consult your appliance’s manual for specific instructions on filter maintenance.
  • Pre-rinse solid debris: Scrape off excess food scraps before loading dishes to prevent unnecessary strain on the filter.
  • Use appropriate cleaners: Stick to dishwasher-safe cleaners when tackling the filter to avoid damage to essential components. We recommend the range of Aktivo cleaning products for best results.

Dont’s

  • Avoid harsh chemicals: Skip the heavy-duty chemicals that could harm the filter or the dishwasher’s interior.
  • Don’t skip regular maintenance: Regularly clean your filter so that your dishwasher works efficiently.
  • Don’t overload the dishwasher: Overloading can lead to poor cleaning and put extra stress on the filter.

How to clean your dishwasher filter

Step 1: Safety first

Before you start any maintenance, make sure your dishwasher is turned off and unplugged.

Step 2: Locate the filter

The filter is typically found at the bottom of your dishwasher. The exact location can vary depending on the model, so refer to your dishwasher’s manual for guidance. It’s often at the base of the dishwasher, underneath the bottom spray arm.

Detaching dishwasher filter

Step 3: Remove the bottom rack

Gently pull out the bottom rack to access the filter. This will give you a clear view and better reach to the filter components.

Step 4: Detach the filter assembly

Depending on your dishwasher model, there might be a combination of parts that make up the filter assembly. Common elements include a cylindrical filter, a fine mesh screen, and a coarse mesh screen. Detach these components carefully.

Washing dishwasher filter

Step 5: Rinse off loose debris

Take the components to the sink and rinse them under warm, running water. Use a soft brush, or an old toothbrush, to gently scrub away any stubborn debris. This initial rinse will make the deep cleaning more effective.

Step 6: Soak in warm, soapy water

Fill your sink or a basin with warm water and add a small amount of mild dish soap. Let the filter components soak for 15-20 minutes. This will help break down grease and grime, making it easier to clean.

Scrub dishwasher filter

Step 7: Scrub away residue

After the soak, use the soft brush to scrub away any remaining residue on the filter components. Be thorough but gentle, ensuring not to damage any delicate parts.

Step 8: Inspect for damage

While cleaning, keep an eye out for any signs of damage to the filter components. Cracks, tears, or warping can compromise the effectiveness of the filter, and damaged parts may need replacement.

Step 9: Check the drain area

Inspect the drain area beneath the filter for any lodged debris. Remove any foreign objects carefully to prevent potential clogs.

Step 10: Reassemble the filter

Once you’re satisfied that the filter components are clean and in good condition, reassemble them as per the manufacturer’s instructions. Double-check that everything fits snugly and securely.

Step 11: Run a test cycle

Before putting the filter back in place, run a short test cycle without any dishes. This ensures that everything is in working order and that there are no leaks or issues.

Step 12: Wipe down the exterior

While you have the bottom rack pulled out, take a moment to wipe down the interior of the dishwasher. Use a damp cloth to remove any lingering residue.

Step 13: Replace the bottom rack

Slide the bottom rack back into place.

Step 14: Run a cleaning cycle

Consider running a dishwasher cleaning cycle with dishwasher descaler to ensure the entire system is free from mineral deposits and lingering odours.

Step 15: Regular check-ups

Set a reminder for monthly filter check-ups. Consistency is key to maintaining a smoothly running dishwasher.

By following these steps, you’ll ensure your dishwasher continues to be the reliable kitchen assistant you’ve come to depend on. Happy dishwashing!
