SOLUTION
NOTE: If the dishwasher is not used daily, you can run a rinse cycle with the partial load daily until a
full load is ready to run, or use the Top Rack Only option (on some models) for partial loads.
Run a vinegar rinse through the dishwasher by putting 2 cups (500 mL) of white vinegar in an upright
glass measuring cup in the lower rack. Run a normal cycle with the Heat Dry option turned off. Do
not use detergent.
The dishwasher may not be draining properly, see "Water Remains In The Tub/Will Not Drain" in the
"Troubleshooting" section.
NOTES:
Surging sounds can occur periodically throughout the cycle while the dishwasher is draining.
I
Normal water valve hissing may be heard periodically.
I
A normal snap sound may be heard when the detergent dispenser opens during the cycle and
I
when the door is opened at the end of the cycle.
Improper installation will affect noise levels.
I
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 "Dishwasher Use" section).
Check filter to ensure it is properly installed. Clean it if needed. (See "Cleaning Instructions" in the
"Filtration System" section for details.)
Select the proper cycle and option for the type of soils. The ProWash™ or the Heavy Duty cycle with
the ProScrub (on some models) 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 foam or suds are detected by the dishwasher sensing system, the dishwasher may not operate
properly or may not fill with water.
Suds can come from:
Using the incorrect type of detergent, such as dish detergent for hand washing dishes, laundry
I
detergent, or hand soap.
Not replacing the rinse aid dispenser cap after filling (or refilling) the rinse aid.
I
Using an excessive amount of dishwasher detergent.
I
Call for service.
If no water was present in the machine at any time during a heated wash cycle, the cycle will end and
the Clean LED will not come on. See "Will Not Fill" in the "Troubleshooting" section.
If the sanitized light is blinking, the load is NOT sanitized. The cycle was interrupted in the final rinse,
or the temperature for your water heater is set too low. Set your water heater to 120ºF (49°C).
Improper loading can cause dishes to become chipped or damaged. (See specific loading
instructions within this guide.)
Blinking LED's will occur when the cycle is paused or when the cycle has been interrupted by
opening the door. In this case, the Start/Resume button LED, the Cycle Status Indicator LED(s), and
the countdown bars on the Cycle Status Display all blink together to indicate that attention is
needed. See "Start or Resume a Cycle" in the "Dishwasher Use" section.
Blinking LED's can also occur when certain errors have been detected. In this case, the Clean/
Complete LED will blink 4 times in a row with a pause in between each set of blinks. When this error
occurs, the controls will lock out and not allow another cycle to be started.
Call for service.
NOTES:
Liquid rinse aid is necessary for drying and to reduce spotting.
I
Use the correct amount of detergent.
I
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 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 and Sani Rinse 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
I
items. Put 2 cups (500 mL) of white vinegar in a glass measuring cup in the lower rack. Run a
normal cycle with the Heat Dry option turned off. No detergent is needed.
