Solutions
• Water supply should be at least 120 °F
for best wash performance.
• Do not overload the dishwasher.
• See the Operation section.
• Water pressure should be between 20
and 80 psi.
• Add the recommended amount of
detergent. See the Operation section.
• Refill rinse aid dispenser.
• Remove all dishes, silverware and
silverware holder from dishwasher.
Only racks should remain in tub. For
best results, use citric acid powder (can
be found in canning sections of most
grocery stores or online). Measure 3
tablespoons (40 g) of citric acid powder.
Fill main wash compartment with
measured powder. If you cannot find
citric acid powder, pour approximately
one cup (200-300 mL) of white vinegar
into shallow bowl and place in upper
rack. Run Machine Clean cycle. Do not
use detergent.
• Detergent cover opening.
• Drain pump at the beginning of drain
cycle.
• Adjust leveling feet.
• Reposition the dishes.
• Check and refill the rinse agent
dispenser if empty.
• Connect power supply.
• Clean the holes of spray arms.
• See the Height Adjustable Upper Rack
section.
• Close the door until the dishwasher and
dishes have cooled down. The chiming
will stop if the door is closed or the
interior temperature has cooled.
