Dishes are removed too soon:
Do not empty your dishwasher immediately after washing. Open the door slightly so that the steam can escape. Begin with unloading the dishwasher when the dishes are only hand warm. Empty the lower rack first. This prevents water from dripping off dishes in the upper rack.
Wrong program selection:
In short period programs, the wash temperature and therefore the cleaning performance is lower. Choose a program with a longer washing time.
Washing cutlery with worn surface:
Evaporation of water is more difficult with these items. Cutlery or dishes of this type are not suited for dishwashers.
Dishes are not cleanImproper loading:
Load the dishwasher as suggested in this manual. Wrong program selection:
Select a program that washes at a higher temperature or takes a longer amount of time.
Spray arms are not turning:
Check if the spray arms are blocked from moving freely.
Clogged filters:
Clean all filters as described in this manual.
Filters are not placed in their proper positions:
Check if all filters are placed in their proper positions.

The hardness is not selected properly; too little salt is being used:
Call water supplier and ask for local hardness in grains per gallon or ppm.
Salt loss (models with salt container):
Check whether the lid of the salt container is firmly closed. Use the funnel to pour in special salt. Begin the Rinse and Hold program right after filling in salt. After the program is complete, check whether the lid may have loosened.

The smell of a new machine disappears after a few wash cycles with detergent.
Filters are dirty:
Clean all filters as described in this manual.
Dirty dishes standing in the machine for a few days without being washed:

Food leftovers are staying on the dishes for too long: Remove coarse dirt under running water and carry out the Rinse and Hold program every two days without detergent.
The machine is not grounded properly:
Check the grounding of the system. Static electricity may eat holes into metal and cause irreparable damages to surfaces.
Cutlery parts from low-grade rust-free steel:

Spotting and filmingHard waterUse the maximum recommended amount (3 tablespoons of dish- washer detergent.
• Wash and rinse load as usual
• Remove all metal items from dishwasher.
• Do not add detergent.
• Pour two cups of vinegar into a bowl and set it on the bottom rack of the dishwasher.
• Run the dishes through an entire wash program. If the vinegar rinse doesn’t work, repeat the above process substituting cup citric crystals (available at most drug stores) for the vinegar.
Wiping with a damp cloth should remove spots from metal items. For sterling silver and silver plated flatware, rub with a towel, or use a good cream silver polish.
Filter systemCheck filter system to be sure it is clean and properly installed
No rinse aidDoes the rinse aid dispenser need to be filled? (NOTE: Use only in hard water areas.)
Too little water Dishwasher detergentCheck that the water valve is fully opened. Make sure that the water pressure is between 18 and 176psi. Check the filter inlet valve.
Use only the correct amount of dishwasher detergent according to the hardness of the water and the wash program you have selected. Do not use old or caked detergent. Store the detergent in a dry place and in a closed container.
Items not loaded properlyChange the dishwasher detergent if the results is still unsatisfactory
Check that you loaded the items according to the instructions in the owners guide. Do not overload. Make sure water can reach all soiled surfaces.
Wash arms rotate poorly or standing stillCheck that both wash arms can rotate freely and that items do not obstruct the movement of the wash arms. Lift the arms and make sure that no grains of dirt, etc., retard the rotation of the wash arms. If necessary, clear the obstruction, refit the arms and check that they rotate freely.
Strainer blockedMake sure that the holes in the wash arms are not blocked be dirt. If necessary, clear the holes with a pointed object.
Excess foam in the MachineCheck the strainer. Clean if necessary.
Flatware incorrectly loadedUse only dishwasher detergent.
Pay particular attention to spoons so they do not nest in each other and prevent water penetration.
Marks and discolorationAluminum utensils rubbing especially light weight foilBe sure aluminum utensils, type pans, do not touch dishes. To remove spots, use a nonabrasive cleaner.
Small particles deposited on itemsWash arm of arms not rotating freelyBe sure a utensil or handle has not prevented their turning.
DetergentUse only fresh detergent, store in a Tightly closed container in a cool dry place. Fill dispenser only when ready to start the dishwasher. Use the recommended amount of detergent, especially with hard water.
Low water pressure Improper loading of dishesCheck that the water valve is fully open. Make sure that the water pressure is between 18 and 176psi.
Load dishes to prevent water and detergent from being trapped in or between items. Water should circulate freely.
Yellow or brown marksIron or manganese in waterTemporary solution: Pour 1 teaspoon to 1 tablespoon of citric acid crystals in instead of the pre- wash detergent directly on the inside of the door. Follow this per- wash with a full detergent wash. Use the pots/pans or normal wash cycle. Permanent solution: install an iron removal system in the water supply.
Copper with sterling silverYellow film on sterling silver results when washing copper items in the same load. Silver polish usually removes the stain.
Tea or coffee (tannic acid)Tea or coffee can stain cups. Remove stains be hand, using a solution of /2 cup bleach and 3 cups warm water. (Do not use on sterling silver or silverplate.)
Discoloration of stainless steel, silverplate or sterling silverAllowing salty or acidic food to remain on flatewareRinse flatware that is to stand several hours before washing.
Stainless steel contacting silver.Do not put stainless steel and silver Flatware in the same silverware basket compartment. Direct contact between these metals can cause permanent damage to silver. Clean stained items with silver polish. Do not use abrasives on stainless steel or silver.
Distortion of plasticsPlastic item has low heat tolerancePlastics vary in their ability to tolerate heat. Check washing instructions for all plastic items to be sure they are dishwasher safe. If they are, place in upper rack away from the heating element.
Marks on melamine and plasticsPorous materialUse a special cleaner for plastic. DO NOT use bleach or scouring powder on these materials.
Detergent left in detergent compartmentCompartment cover blockedThe cover may not be opening be opening because of improperly loaded items. Move dishes that may be blocking it.
Old detergentIf detergent is hard or caked in the box, throw away. Use only fresh detergent. Add detergent just before starting the dishwasher.
Cloudy film on glass-ware-etching of glassToo much detergent, especially in soft waterIf vinegar or citric acid rinse doesn’t remove film, the cloudiness is “etching”. This is permanent. To prevent etching, use the least amount (one teaspoon) of recommended dishwasher detergent if you have soft water.
Use a good quality of dishwashing detergent and rinse aid. Do Not overload the machine. Water should circulate freely to assure adequate rinsing and draining. Use drying without heat.
Dishes not dryNon-heat dryingBe sure to select heated drying for best results. Allow more drying time when using non-heat drying.
No rinse aidFill rinse aid dispenser. Rinse aid helps dishes to dry faster. NOTE: Use rinse aid with hard water only.
Plastic items.Certain plastic materials are difficult to dry. Plastics may need towel drying.
Improper loading or unloadingDo not overload or nest items. Be sure all surfaces drain well. Load items with concave bases so as much water as possible can run off. Unload the lower rack first. Water from dishes in the upper rack may be spilling onto the lower rack.
Dry cycle interruptedIf the door is opened during the heated dry cycle, the heating element comes back on after the door is closed. If the dishwasher door is opened immediately after the dry cycle is completed and then shut again, the vent door is closed, trapping warm humid air. It is best then to leave door open slightly.
Chipping or breaking of glasswareImproper loadingDo not overload. Load between prongs, not over them. Glasses loaded over prongs are not supported and may break, make sure glassware is secure. Always use upper rack for delicate items. Use the light/china cycle.
