PROBLEM CLOUDY OR SPOTTED DISHWARE (AND HARD WATER SOLUTION) ETCHING (PERMANENT CLOUDINESS) LEAKING WATER TUB IS DISCOLORED SOLUTION Add or adjust the amount of liquid rinse aid for better drying and to reduce spotting. See the "Detergent and Rinse Aid" section. Use the correct amount of detergent. Confirm that the cloudiness is removable by soaking the item in white vinegar for 5 minutes. Dry the item. If the cloudiness disappears, it is due to hard water. Adjust the amount of detergent and rinse aid. See "Hard Water (White Residue on Dishwasher Interior or Glassware)" in the "Troubleshooting" section. If it does not come clear, it is due to etching (see below). Be sure the incoming water temperature is set at 120°F (49°C). Try using the High Temp Wash and Sani Rinse options. To remove spotting run a vinegar rinse through the dishwasher using the description in the Cleaning and Maintaining the Interior section. This is an erosion of the surface of the glassware and can be caused by a combination of water that is too hot, from using too much detergent with soft water, or by pre-washing. Detergent needs food soil to act upon. If etching has occurred, the glassware is permanently damaged. To avoid further etching, adjust the detergent amount to match the water hardness, stop pre-washing, and use water heating options only when incoming water temperature is below 120°F (49°C). Be sure dishwasher has been installed properly and is level. Suds can cause the dishwasher to overflow. Measure the detergent accurately and use only detergents designed for use in a dishwasher. Less detergent is needed in soft water. Try another brand of detergent if sudsing continues. To avoid rinse aid leaking from the dispenser, be sure the lid is securely attached and avoid overfilling. High iron content in the water can discolor the tub. Tomato-based and other foods, can discolor the tub or dishware. Large amounts of food with curry, chili powder, paprika, mustard and similar spices and tomato-based foods should be removed from the dishes before loading. A citrus-based cleaner can be used to clean the tub. 15

PROBLEM
SOLUTION
CLOUDY OR SPOTTED DISHWARE
(AND HARD WATER SOLUTION)
Add or adjust the amount of liquid rinse aid for better drying and to reduce spotting. See
the “Detergent and Rinse Aid” section.
Use the correct amount of detergent.
Confirm that the cloudiness is removable by soaking the item in white vinegar for 5
minutes. Dry the item. If the cloudiness disappears, it is due to hard water. Adjust the
amount of detergent and rinse aid. See “Hard Water (White Residue on Dishwasher
Interior or Glassware)” in the “Troubleshooting” section. If it does not come clear, it is
due to etching (see below).
Be sure the incoming water temperature is set at 120°F (49°C).
Try using the High Temp Wash and Sani Rinse options.
To remove spotting run a vinegar rinse through the dishwasher using the description in
the Cleaning and Maintaining the Interior section.
ETCHING (PERMANENT
CLOUDINESS)
This is an erosion of the surface of the glassware and can be caused by a combination of
water that is too hot, from using too much detergent with soft water, or by
pre-washing. Detergent needs food soil to act upon. If etching has occurred, the
glassware is permanently damaged. To avoid further etching, adjust the detergent
amount to match the water hardness, stop pre-washing, and use water heating options
only when incoming water temperature is below 120°F (49°C).
LEAKING WATER
Be sure dishwasher has been installed properly and is level.
Suds can cause the dishwasher to overflow. Measure the detergent accurately and use
only detergents designed for use in a dishwasher. Less detergent is needed in soft water.
Try another brand of detergent if sudsing continues.
To avoid rinse aid leaking from the dispenser, be sure the lid is securely attached and
avoid overfilling.
TUB IS DISCOLORED
High iron content in the water can discolor the tub.
Tomato-based and other foods, can discolor the tub or dishware. Large amounts of food
with curry, chili powder, paprika, mustard and similar spices and tomato-based foods
should be removed from the dishes before loading.
A citrus-based cleaner can be used to clean the tub.
