It is recommended that the spray arms be cleaned once every two weeks. 3 Remove food particles by rinsing or shaking the spray arm. 4 If any food residue blocks the spray arm holes, remove it with a pin or any sharp tool. 5 After removing the food residue, clean the spray arms holes under running water.
TROUBLESHOOTING 45 TROUBLESHOOTING Q: Does this dishwasher require a rinse aid to be used? A: Rinse aid is strongly recommended to enhance the drying performance of the dishwasher. In order to be more energy efficient, the hybrid drying system does not use a heating element to assist in drying, so a rinse aid plays an integral role in the drying process. If a rinse aid is not used, water may remain on the dishes and the tub.
TROUBLESHOOTING Q: What is the hybrid drying system? A: The dishwasher does not rely on a heating element for the drying process; instead, it relies on the heat that is retained by the dishes and the tub during the wash and rinse cycles to turn the moisture in the tub into humidity. Warm, moist air in the dishwasher is then pulled into a condensing duct in the door by a fan. The air then cools, which causes the humidity to condense.
TROUBLESHOOTING 47 What is Control Lock and how is it activated? A: Control Lock is a feature that prevents the controls from being changed during the cycle. It does not prevent the door from being opened or the unit from being powered off. To activate or deactivate, press and hold Half Load and Energy Saver simultaneously for three seconds. Q: Can I add an extension to the drain hose? A: If an extension drain hose is required, use 5/8" or 7/8" inside diameter, 2-3 ft.
TROUBLESHOOTING Before Calling for Service The appliance is equipped with an automatic error-monitoring system to detect and diagnose problems at an early stage. If the appliance does not function properly or does not function at all, check the following before you call for service.

TROUBLESHOOTING Problem Dishwasher chimes if panel is touched during operation. Possible Cause Bumping into or touching the control panel during operation may result in a disabled button sound. Only the Power, Start, and Control Lock buttons are enabled during operation to prevent cycle settings from being changed inadvertently. Solutions ••Button sounds can be turned off by pressing and holding Half Load for three seconds. ••The end of cycle chime and safety alert sounds will still sound.
