Step-by-Step Filter Cleaning Guide
Step 1: Preparation
Turn off the dishwasher and ensure it's completely cool. Remove the bottom rack to access the filter assembly at the bottom of the tub.
Step 2: Locate Filter Assembly
Identify the cylindrical filter assembly in the center of the dishwasher floor. This typically consists of an upper and lower filter component.
Step 3: Remove Filter Components
Turn the filter assembly counterclockwise to unlock it. Gently lift out the entire filter unit. Some models may have separate upper and lower filters.
Step 4: Clean Filter Components
Rinse filters under warm running water. Use a soft brush to remove stuck-on debris. For tough buildup, soak in warm soapy water for 10-15 minutes.
Step 5: Clean Filter Housing
Wipe down the filter housing area in the dishwasher bottom. Remove any debris or food particles that may have accumulated around the edges.
Step 6: Reassemble Filters
Ensure all components are completely dry. Reinsert the filters in the correct order and orientation. Turn clockwise until they lock into place securely.
Detailed Cleaning Process
Upper Filter Cleaning
Fine mesh filter that catches small food particles. Requires gentle brushing to avoid damage to mesh.
Lower Filter Cleaning
Coarse filter for larger debris. Can be scrubbed more vigorously to remove stuck-on food.
Spray Arm Inspection
Check spray arm holes for clogs while filter is removed. Use toothpick to clear any blocked holes.
Drain Area Cleaning
Clear any debris from the drain area at the back of the dishwasher tub to ensure proper drainage.
