48 TROUBLESHOOTING
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. Room temperature air is also drawn into the duct
to help the air cool down faster. When this moisture condenses into a liquid, it is drained out.
NOTE
• Rinse aid is required to enhance the drying performance. If no rinse aid is used, water may
remain on the dishes and the tub.
Q: Why am I hearing a whistling sound from the dishwasher?
A: It is important to determine the duration of the noise and when it happens (what part of the cycle).
When water is drawn into the dishwasher, a whistling noise can be heard. This is normal. If the water
pressure is too high, it will be louder, so it may be necessary to adjust the water valve to lower the
pressure if the noise is too loud.
Q: What kinds of dishes can be placed in the dishwasher?
A: Ensure that the dishes you place in the dishwasher are dishwasher safe. Plastic dishware will not dry
as effectively as glass and metal dishware. Plastic items do not retain heat as well as glass and metal
dishware. Plastic cups and dishes may require some hand drying before being put away at the end of
the cycle.
Q: Can I run a drain only cycle?
A: To drain standing water, press and hold Start for three seconds until the cycle stops. Once the
dishwasher finishes draining, the power turns off.
Q: Why does my dishwasher continuously chime if I open the door during a cycle or right after the
cycle has finished?
A: This is normal. The dishwasher is letting you know that the interior temperatures of the unit are hot
and to use caution when reaching inside. Once the unit has cooled down, the chiming will stop.
Q: 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 Dual Zone for three seconds.
Q: Can I add an extension to the drain hose?
A: If a drain hose extension is required, use a 5/8" or 7/8" inside diameter, 2 ft ~ 3 ft. length hose and a
coupler to connect the two hose ends.
Q: An LED is blinking, the machine is chiming, and the dishwasher won't start. What is wrong with
the dishwasher?
A: This is a safety feature. The door must be closed within four seconds of pressing the Start button. If
the door is not closed within four seconds, an LED flashes, an audible alert sounds, and the
dishwasher does not operate. To start the dishwasher, open the door and either close the door and
press Start (front controls) or press Start and close the door within four seconds (top controls).
Q: Should I pre-rinse dishes before loading them?
A: No, you don't need to pre-rinse the dishes before loading especially if using the Normal and Auto
cycles. The dishwasher washes dishes clean without pre-rinsing.
