NOTE: DO NOT USE HAND DISH DETERGENT
Using a detergent that is not specifically designed for dishwashers will
cause the dishwasher to fill with suds. During operation, these suds will
spill out of the dishwasher vents.
Since so many detergent containers look similar, store the dishwasher
detergent in a separate space from all other cleaners. Show anyone who
may use the dishwasher where the correct detergent is stored.
While there may be no lasting damage to the dishwasher by using
dishwashing detergent that is not formulated to work with dishwashers,
your dishes may not get fully clean.
