NOTES:
• Surging sounds can occur periodically throughout the cycle while the dishwasher is draining.
• Normal water valve hissing may be heard periodically.
• A normal snap sound may be heard when the detergent dispenser opens during the cycle and
when the door is opened at the end of the cycle.
• Improper installation will affect noise levels.
Press and hold HI TEMP WASH for 3 seconds to turn the audible tones on or off.
Be sure the filters are properly installed.
A thumping sound may be heard if items extend beyond the racks and interfere with the wash arms.
Readjust the dishware and resume the cycle.
Be sure the dishwasher is loaded correctly. Improper loading can greatly decrease the washing
performance (see "Prepare and Load the Dishwasher").
Select the proper cycle and option for the type of soils. The Jet Clean Plus Steam cycle with the
Steam Sanitize option can be used for tougher loads.
Be sure the incoming water temperature is at least 120°F (49°C).
Use the proper amount of fresh detergent. More detergent is needed for heavier-soiled loads and
hard water conditions.
Scrape food from dishes prior to loading (do not prerinse).
If the sanitized light is blinking, the load is NOT sanitized. The cycle was interrupted in the final
rinse, or your water heater is set too low. Set your water heater to 120°F (49°C).
Improper loading can cause dishes to become chipped or damaged. (See specific loading
instructions within this guide.)
If the START/RESUME light is blinking, press START/RESUME and close the door within 3 seconds.
If the Clean light or any other lights are blinking and the dishwasher will not run, call for service.
NOTES:
• Liquid rinse aid is necessary for drying and to reduce spotting.
• Use the correct amount of detergent.
Confirm that the cloudiness is removable by soaking the item in white vinegar for 5 minutes. 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
"Troubleshooting." 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 Hi Temp and Steam Sanitize options.
To remove spotting, run a vinegar rinse through the dishwasher.
• Wash and rinse the affected dishware and load into dishwasher. Remove all silverware and
metal items. Put 2 cups (500 mL) of white vinegar in a glass measuring cup in the lower rack.
Run a normal cycle with the Heated Dry option turned off. No detergent is needed.
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.
TUB IS DISCOLORED NOTES:
• High iron content in the water can discolor the tub.
• Tomato-based foods can discolor the tub or dishware.
A citrus-based cleaner can be used to clean.
