Purge the System: Top Control Models

• Purging the system helps clear out detergent stuck in the SmartDispense tank. Select the "Pre-Wash," "Added Heat" and "TempBoost" buttons, if so equipped, until the LEDs above go out. Hold down the "Heated Dry" and "Down" arrow buttons together for three seconds; all LEDs should come on. Select the "Added Heat" or "TempBoost" buttons, depending on the model, along with the "Up" arrow button for three seconds. The "Anti Bacteria" LED should come on. Push "Start," then select "Normal" and make sure the "Pre-Wash," "Added Heat," "TempBoost" and "Heated Dry" lights are off. Push "Start" to run a full cycle without using the main motor -- this process takes about an hour and is complete when the "Clean" light illuminates. Open the dishwasher, wipe up any detergent from the door and tub then wash them off with warm water. Open the SmartDispense cap and fill the container with water. Repeat the cleaning instructions then perform a third purge cycle by following the instructions up to the hour-long, main motor off cycle.
