• Check inlet hose for a kink.
• Check water valve inlet for sediment and clean if necessary.
Dishwasher will not drain/ Water in tub bottom• If hooked up to a food waste disposer, be sure the knock-out is removed from the disposer inlet
• Check for food obstruction in the drain or disposer.
• Check drain hose for a kink.
• Check your home's circuit breaker or fuse box.
• Check that the cycle is completed.
Dishwasher adds water at end of cycle• This is normal. The sensor (select models) in the pump must stay submerged so a short fill of water is added after the cycle's last drain.
Detergent cup is not empty• Check that the cycle is completed.
• Be sure dispenser is not blocked.
• Use fresh detergent stored in a cool, dry place.
Detergent cup is not empty• Check that the cycle is completed.
• Be sure dispenser is not blocked.
• Use fresh detergent stored in a cool, dry place.
Dishwasher seems noisy• A water valve hiss during fill is normal.
• Water circulation sounds are normal.
• A thumping sound may be a wash arm bumping an item that is extending beyond the racks. Readjust load to avoid obstructing wash arm.
• Chopping or grinding sounds may be heard as the internal food disposer chops hard items like fruit seeds, nuts, etc.
• Humming during the drain is normal.
• A snap noise is the detergent cup lid hitting the door liner when the dishwasher door is opened at the end of the cycle. This is normal.
• Proper installation affects the noise level.
Cycle takes too long (Heating light stays on)• High Temp or Sanitize has been selected and the cycle is extended to heat water.
• Check to see that the incoming water temperature is 120° F (49° C).
Dishwasher has an odor• Run dishes being held in the dishwasher through a Rinse Only cycle.
• Many dishwashers have a “new" smell when first installed. This will dissipate with use.
• Dishwasher may not be draining properly.
• For a strong odor, place baking soda in both sides of the detergent cup. Select Light Wash cycle and allow the water to circulate for about 10 minutes. Interrupt the cycle by unlatching the door and let it stand overnight. Restart the dishwasher by latching the door and allow it to complete the cycle. Another alternative is to use a dishwasher cleaning product such as Jet-Dry Dishwasher Cleaner.
Dishwasher leaks• Check that the dishwasher is level.
• Suds can cause the dishwasher to overflow. Measure the detergent carefully 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.
• Follow directions closely on how to add a forgotten item.
• To avoid rinse aid leaking from the dispenser, be sure the lid is securely attached.
Display time suddenly drops or increases by several minutes (select models)• This is normal when the Auto Clean (select models) or Normal Wash cycle is selected and the dishwasher decides to skip or add a drain and refill.

• The lock indicator flashes and the countdown display (selected models) flashes an “L" if a pad is pressed while the control lock is enabled.
Glasses are cloudy/spotted• Select Extra Rinse (select models).
• Check water temperature. Incoming water should be 120° F (49° C).
• Always use a rinse aid.
• Confirm that the cloudiness is removable by soaking the item in white vinegar for approximately 5 minutes. If removed, the problem is due to hard water. Adjust detergent amount being used to match water hardness. Be sure detergent is fresh, stored properly and is a high quality brand.
• If cloudiness is not removable, it is etching. This is an erosion of the surface of the glassware and can be caused by water that is too hot from using too much detergent or by prewashing. Detergent needs food soil to act upon. If etching has occurred, the glassware is permanently damaged. To prevent further etching, adjust the detergent amount to match the water hardness, stop prewashing, and use water heating options only when incoming water temperature is below 120° F (49° C).
Food soil remains on dishes• Check water temperature.
• Run hot water at the sink before starting the dishwasher.
• Select High Temp option.
• Check water hardness and adjust detergent amount accordingly .
• Use fresh detergent stored in a cool dry place.

• Load the utensil basket with knife handles up and spoon and fork handles down through the slots in the covers.
• Do not place glasses over tines.
• Prior to loading, scrape off burnt on foods and wipe the starchy film from utensils used with pasta, rice and oatmeal. These soils require more energy than the rest of the load to clean.
Items washed in the dishwasher or the dishwasher tub itself are stained/ discolored• Aluminum utensils or pans can leave marks when they rub against other items. Leave a slight space between items.
• Iron deposits in the water can leave a yellow, brown or orange film on dishes or the dishwasher tub. A rust filter may be needed, check with a water treatment company.
• Separate silver or silver-plated silverware from stainless steel. These metals can be damaged by contact with each other during washing.
• Color from tomato sauces may adhere to the interior parts of the dishwasher . If light staining has occurred, leave the door open to oxidize the stain away. Change dishwasher detergent and be sure to use a dishwasher detergent that contains chlorine to better fight staining.
• Certain dishwasher detergents may stain silver. Try another brand of detergent.
Items not properly dried/ moisture is present on the dishwasher interior after the dry cycle• Be sure Heated Dry is selected.
• Water droplets may form on the inner door as part of the drying process.
• Use a rinse aid separate from the detergent like Jet Dry* or Cascade Rinse Aid* regularly, to improve drying. Turn the rinse aid selector toward the MAX setting.
• Check water temperature.
• Select Sanitize.
• Increase detergent amount to match water hardness .
• Load properly
• Plastic and items with non-stick surfaces are difficult to dry because they have a porous surface which tends to collect water droplets. Towel diying may be necessary.
• Glasses and cups with concave bottoms hold water and require towel drying. Locate these items on the more slanted side of the rack for improved results.
Dishware is chipped• Load dishes according to instructions so they do not strike each other .
• Washing fine antique china/crystal in the dishwasher is not recommended.
• Do not load glasses over the tines.
