   • Do not load items that are not heat resistant or have decorative metal trim.

2. Add the detergent.
   • Using the guidelines in this manual, fill the detergent cup with the recommended amount of detergent and close the lid. If a prewash is desired, the recess on top of the lid should also be filled with detergent.

3. Turn on the dishwasher.
   • To turn on the display panel, press the Power button.

Adding Cleaning Products

Adding Detergent to the Dispenser

• Remove the label on the dispenser prior to running the dishwasher for the first time

• The amount of detergent needed depends on the cycle, load size, and soil level of dishes.

• Put detergent into the detergent compartment before starting any cycle, except the Rinse (Download Cycle: P3) cycle.
  WARNING

• Dishwasher detergent and rinse aid contain chemical components, like all other household detergent. So, they must be kept out of the reach of children.

CAUTION

• Use only detergent intended for dishwashers. Incorrect detergent may cause the dishwasher to fill with suds during operation. Excess suds may reduce wash performance and may cause the dishwasher to leak.
• To avoid damaging the dispenser and blower cover, do not use them to pull up and close the dishwasher door.
  

NOTE

• After completion of the wash program, check whether the detergent was completely washed out.
• Some dishwasher detergent tablets may become stuck in the dispenser due to their excessive size. Tablets can be placed onto the base of the wash tub next to the filter before starting the cycle.
• Too much detergent can leave a film on dishes and in the dishwasher, resulting in poor wash performance.
• If dishwasher detergent tablets are used without liquid rinse aid, the dishes and dishwasher interior will have excessive moisture. Select the Dry Boost option for bette drying performance.
• Using liquid rinse aid improves drying performance by allowing water to drain off of dishes after the final rinse.
• Do not use detergent tablets for shorter wash cycles. The tablet may not dissolve completely, causing detergent residue on dishes and inefficient cleaning.
• Using a wash booster helps remove spots, residue, and the white film caused by hard water. It does not help remove excess detergent residue.

1. Push the button on the dispenser lid to open the cover.

2. Add dishwashing detergent to the main wash compartment until the level is between the lines marked 15 and 25.
   • Fill to over the 25 line for hard water or heavily soiled loads.
   • Fill to the 15 line for soft water or lightly soiled loads.
   

3. Slide the detergent lid closed until it clicks.
   

4. If a prewash is desired, fill the recessed prewash compartment area on the lid with detergent.

Adding Rinse Aid to the Dispenser
The Rinse Aid Refill LED appears in the display when more rinse aid is needed.
The use of rinse aid is recommended to prevent water spots on dishes and to enhance drying performance.

NOTE

• Only use liquid rinse aid in the dishwasher.
• Do not overfill the rinse aid dispenser.
• Wipe off any spilled rinse aid around the dispenser.

1. Open the rinse aid lid by lifting up the flap.
   

2. Add a liquid rinse aid to the maximum fill level. Allow the rinse aid to settle in the dispenser while filling, or air bubbles may result in poor drying performance. Avoid overfilling the dispenser.
   

3. Close the lid to lock the dispenser. Rinse aid is dispensed automatically during the final rinse cycle.
   

Rinse Aid Dispenser Adjustment
The dispenser has five adjustment levels. The dishwasher is programmed at the factory for a rinse aid dispenser level of 2. This can be checked and adjusted from the control panel.
NOTE

• Adjust the setting higher if you have hard water and notice calcium buildup on your dishes.
• Setting the rinse aid control too low will contribute to spotting and streaking on dishes and poor drying performance.
• Setting the control too high can cause foaming, which will cause poor wash performance.

1. Ensure the appliance is off.
2. Press Power and Remote Start simultaneously to enter the Option Setting Mode.
3. Press Dry Boost to change the rinse aid dispenser setting. Each press of the button changes the setting one step from L0 to L4.
4. Once the desired rinse aid dispenser setting is selected, press Start to save.

Refilling the Rinse Aid
How often the dispenser needs to be refilled depends on how often dishes are washed and the rinse aid setting used.

• The Rinse Aid Refill LED flashes when more rinse aid is needed, unless the rinse aid dispenser setting is set to L0.
