Before You Begin

  1. Safety First: Turn off the dishwasher at the circuit breaker to prevent electrical shock.

  5. Prepare Containers: Place towels around the base and have your pan or bucket ready to collect water.
Warning: Always disconnect power before attempting any manual draining procedures to avoid electrical hazards.

Draining Methods

Method 1: Using the Drain Hose

  1. Locate Drain Hose: Find the drain hose at the back of the dishwasher or under the sink.
  2. Position Container: Place your bucket or pan under the drain hose connection point.
  3. Disconnect Hose: Carefully loosen the hose clamp and detach the drain hose from the air gap or garbage disposal.
  4. Drain Water: Allow water to flow into your container. You may need to guide the hose to ensure proper drainage.
  5. Reconnect Hose: Once drained, securely reattach the drain hose and tighten the clamp.

Method 2: Through the Filter System

  1. Remove Lower Rack: Pull out the bottom dish rack to access the filter area.
  2. Locate Filter Assembly: Find the cylindrical filter in the center of the dishwasher base.
  3. Remove Filter: Turn the filter counterclockwise and lift it out carefully.
  4. Collect Water: Use a wet/dry vacuum or turkey baster to remove standing water from the sump area.
  5. Clean and Replace: Clean the filter and reinstall it by turning clockwise until it locks in place.

Method 3: Emergency Drain Procedure

  1. Access Pump Area: Remove the kick plate at the bottom front of the dishwasher.
  2. Locate Drain Pump: Find the drain pump assembly at the front bottom of the unit.
  3. Emergency Drain Tube: Some models have a small emergency drain tube near the pump.
  4. Direct Drainage: Place a shallow pan and carefully direct the tube to drain water into the container.
  5. Replace Components: Once drained, ensure all components are properly replaced and secured.
