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.
