PROBLEM HARD WATER (WHITE RESIDUE ON DISHWASHER INTERIOR OR GLASSWARE) ODORS NOISY FOOD SOILS REMAIN ON DISHES DID NOT SANITIZE DAMAGE TO DISHWARE BLINKING LIGHTS CLOUDY OR SPOTTED DISHWARE (AND HARD WATER SOLUTION) SOLUTION NOTE: Extremely hard water mineral deposits can cause damage to the dishwasher and make it difficult to achieve good cleaning. A water softener is strongly recommended if the hardness is 15 grains or more. If a water softener is not installed, the following steps may help: Use a commercial cleaner designed for dishwashers once per month. Always use a rinse aid. Always use a high-quality, fresh detergent. Use a detergent booster/water softener additive designed for dishwashers. NOTE: If the dishwasher is not used daily, you can run a rinse cycle with the partial load until a full load is ready to run. 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 Heated 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 "Troubleshooting." 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. 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" in the "Dishwasher Use" section. Select the proper cycle and option for the type of soils. PowerBlast® with the Sanitize option can be used for tougher loads. Be sure the incoming water temperature is at least 120°F (49ºC). 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 the water heater is set too low. Set the water heater to 120ºF (49ºC). 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 4 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 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 (49ºC). Try using the Hi Temp and 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. 13
