PROBLEM HARD WATER (WHITE RESIDUE ON DISHWASHER INTERIOR OR GLASSWARE) ODORS NOISY FOOD SOILS REMAIN ON DISHES DISHES DIRTY/SUDS IN DISHWASHER/CYCLE NOT COMPLETE DID NOT SANITIZE DAMAGE TO DISHWARE BLINKING LIGHTS SOLUTION NOTE: Extremely hard water mineral deposits can cause damage to your dishwasher and make it difficult to achieve good cleaning. A water softener is strongly recommended if your hardness is 15 grains or more. If a water softener is not installed, the following steps may help: Use a commercial cleaner (affresh®† dishwasher cleaner recommended) 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 2-cup 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. 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. 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 the "Dishwasher Use" section. Select the proper cycle and option for the type of soils. The PowerBlast® cycle with the High Temp Wash 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 detergent, or hand soap. ■■ Not replacing the rinse aid dispenser cap after filling (or refilling) the rinse aid. ■■ Using an excessive amount of dishwasher detergent. ■■ Inadequate rinsing off detergent from dishes washed by hand before loading them into the dishwasher. 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 indicator 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 indicators will occur when the cycle is paused or when the cycle has been interrupted by opening the door. If the START light is blinking, press the START keypad and close the door within 4 seconds. See START a Cycle in the "Dishwasher Use" section. If the Clean light or any other lights are blinking and the dishwasher will not run, call for service. †affresh® is a registered trademark of Whirlpool U.S.A. 14
