The best way to eliminate spots on your dishes is to install a whole house water softener in your home.
If a water softener is already installed or you do not plan on installing one,
try adding an “Extra Rinse” option as part of the wash cycle to help minimize this condition.
To add an Extra Rinse to the cycle, select the wash cycle then press extra rinse.
Note:
When selecting the “Extra Rinse” cycle times and water usage will be increased from normal use.
To remove hard water build up in tub
Remove all dishes, silverware and silverware holder from the dishwasher. Only the racks should remain
in the tub.
Fill a measuring cup with white vinegar approximately 14~17ounces(400~500mL), place the measuring
cup in the lower rack.
Run a “Normal” cycle and select “Extra Rinse” and “Sanitary”, then close the door.
DO NOT USE ANY DETERGENT
Note:
Make sure to let the dishwasher complete the entire cycle. The cleaning method should only be
done as needed.
