Loading" section. Use a liquid rinse aid to speed drying.

Chipping of dishes
Did you load the dishwasher properly? Load the dishes and
glasses so they are stable and do not strike together from

out slowly.
NOTE: Antiques, feather-edged crystal, and similar types of
china and glassware might be too delicate for automatic
dishwashing. Wash by hand.
