Empty liquids from glasses and cups. Foods such as mustard, mayonnaise, vinegar, lemon juice and tomato based products may cause discoloration of stainless steel and plastics if allowed to sit for a long period of time. Unless the dishwasher is to be operated at once, it is best to rinse off these food soils. • Load racks so that large items do not prevent the detergent dispenser from opening. • Check manufacturer’s recommendations before washing items in question. • If the dishwasher drains into a food disposer, be sure disposer is completely empty before starting dishwasher. 6 Dishwasher Dispenser & Detergents (continued) Rinse Aid Rinse aid greatly improves drying and reduces water spots and filming. Water “sheets” off dishes rather than forming water droplets that cling and leave spots. A dispenser, located next to the detergent cup, automatically releases a measured amount of rinse aid during the last rinse. If spotting and poor drying are problems, increase the amount of rinse aid dispensed by rotating the dial to a higher number. The dial is located under the dispenser cap. The indicator will be dark when full and will show clear when it is time to refill. To add liquid rinse aid, turn dispenser cap 1/4 turn counterclockwise and lift out. Pour in rinse aid until liquid touches the indicated fill level. Replace cap. Do not overfill since this can cause oversudsing. Wipe up any spills with a damp cloth. The dispenser holds enough for 35 to 140 washes, depending on setting. Factors Affecting Performance Water Pressure The hot water line to dishwasher must provide water pressure between 20 and 120 psi. Low water pressure may occur when laundry or showers are in operation. Wait until water use is reduced before starting dishwasher. Water Temperature Hot water is needed for best dishwashing and drying results. Water entering dishwasher should be at least 120°F (49°C) to give satisfactory results. To check water temperature entering dishwasher: • Turn on hot water faucet nearest dishwasher for several minutes to clear cool water from pipes. • Hold a candy or meat thermometer in stream of water to check the temperature. • If temperature is below 120°F (49°C), have a qualified person raise the hot water heater thermostat setting. Important: Before starting a cycle, run hot water to clear cool water from pipe.

This list includes common experiences that are not the result of defective workmanship or material in your dishwasher. Food Soils Left on Dishes • Choose another cycle for longer washing time. • Check rack loading section for proper loading—avoid nesting items. • Home water pressure may be too low— should be 20 to 120 pounds per square inch (psi). • Check incoming water temperature. It should be at least 120°F (49°C). (See Factors Affecting Performance.) • Select HI-TEMP WASH option. • Check water hardness. For extremely hard water, it may be necessary to install a water softener. (See Detergent Chart.) • Use fresh detergent. • Check to make sure funnel in top rack is not blocked. • Make sure items are not blocking the spray arms, preventing them from rotating. Dishes not Dry • Select heat dry option. • Make sure the rinse aid dispenser is filled. • Increase the amount of rinse aid. (See Rinse Aid.) • Check the incoming water temperature. Be sure it is at least 120°F (49°C). • Check for proper loading—avoid nesting items. • Plastic items may need to be towel dried. • Cups with a concave bottom will collect water. Glassware/Flatware Spotted or Cloudy • Check water hardness. For extremely hard water, it may be necessary to install a water softener. (See Detergent Chart.) • Water temperature may be low. Avoid extremely low or high temperatures. (See Factors Affecting Performance.) • Avoid overloading and improper loading. (See Preparing and Loading Dishes.) • Use fresh detergent. Old detergent is ineffective. • Make sure rinse aid dispenser is filled. • Check to see that proper amount of detergent is being used for cycle selected. Also, check phosphate level. (See Detergent Dispenser.) • Home water pressure may be too low—it should be 20 to 120 pounds per square inch (psi). Dishware Chipped • Load with care and do not overload. (See Preparing and Loading Dishes.) • Place delicate items in top rack. • Place glasses securely against pins and not over pins. • Load items so they are secure and don’t jar loose when moving racks in and out. Move racks in and out slowly. • Make sure tall glasses and stemware will clear top of tub when rack is pushed in. • Fine antique china and crystal should be hand-washed. 13 Solutions to Common Dishwashing Problems (continued) Dishware Stained or Discolored • Tea and coffee can stain cups. Remove the stains by hand washing in a solution of 1/2 cup (120 ml) bleach and one quart (1 L) of warm ...
