WASHING SPECIAL ITEMS
Most common dishware items can be safely washed in 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.
