an automatic dishwasher. If you have any doubts about
a particular item, check with the manufacturer to see if it
is dishwasher safe. If that isn’t possible, you might wash
one item of a set a few times and compare it to the rest
of the set to determine if washing it in the dishwasher
had any affect on it.
NOTE: ASKO has no control over what is put in our
dishwashers once installed in a customer’s home. You
are solely responsible for what you wash in your
ASKO dishwasher.
