How to clean a clogged dishwasher filter?

 

Understanding Why Your Dishwasher Filter Gets Clogged

 

Dishwasher filters can easily become clogged due to accumulated debris, food particles, soap residues, and even small objects. Regularly cleaning the filter ensures smooth functionality and prevents dishwasher odors or inefficient cleaning cycles.

 

Identify and Locate Your Dishwasher Filter

 

The filter is generally located at the base of your dishwasher interior, near the bottom spray arm. Carefully remove the lower dish rack to expose it. Most dishwasher models in homes from St Louis to Nashville come equipped with one or two filters: a primary cylindrical filter (removable mesh cylindrical unit) and sometimes a secondary flat filter beneath it.

 

Gather the Necessary Tools and Supplies

 

Before starting, ensure you have:

  • Mild dish soap or vinegar
  • Soft bristle toothbrush or sponge
  • Warm water
  • Towel or cloth
  • Rubber gloves (optional)

 

Remove and Clean the Dishwasher Filter Thoroughly

 

Carefully twist and lift the cylindrical filter out. If there is an additional flat filter beneath, remove that as well. Rinse both filters with warm water to clear away visible debris. Then, soak the filters briefly (15-30 minutes) in warm, soapy water or in a solution of vinegar and water for tougher, stuck-on grime. Use your soft bristle brush or sponge to gently scrub away residue and buildup. Avoid using harsh brushes or abrasive pads to prevent damaging the filter mesh.

 

Address Larger or Stubborn Debris

 

Small bits of debris can lodge themselves deep inside parts of the dishwasher, contributing to clogs. Inspect the bottom of your dishwasher, the sump, and the spray arms for any visible particles or debris. Gently remove these obstructions to ensure water freely circulates during washing cycles.

 

Inspect and Wipe the Area Around the Dishwasher Filter

 

After filter removal, clean around the filter seating at the dishwasher bottom with a damp cloth. Removing accumulated grime improves the dishwasher's efficiency significantly.

 

Rinse and Dry Thoroughly Before Reinstallation

 

Rinse both filters thoroughly under warm running water until clean. Pat dry or air-dry completely before placing them back into your dishwasher. Filters should fit securely back into their original position, twisted or locked into place to ensure correct alignment.

 

Run a Short Dishwasher Cycle for Verification

 

After reinstallation, run a brief or rinse cycle without dishes. This ensures everything is securely placed and allows you to check water flow and drainage. Listen closely during the cycle to confirm that water streams freely and efficiently drains, signaling a successful cleaning.

 

Regular Maintenance to Prevent Future Clogs

 

Setting a monthly reminder to clean your dishwasher filters will keep your dishwasher operating effectively. This routine maintenance can prevent inconvenient clogs and reduces the chances of requiring more extensive repairs down the line, whether you're residing in St Louis or Nashville.

By following these straightforward, detailed instructions, you'll maintain optimal dishwasher performance, extend equipment lifespan, and enjoy sparkling clean dishes after every wash.
