Operation

NoiseSome level of noise is normal during operation.Detergent cover opening.Drain pump at the beginning of drain cycle.The appliance is not level.Adjust leveling feet.Nozzle arm knocking against dishes.Reposition the dishes.Water pressure is too high.Adjust water pressure.Is the amount of cutlery in the cutlery basket or cutlery rack small?There is no problem with the product due to noise generated by the small amount of tableware, so use it with confidence.Appliance will not operate.Door is not completely closed.Level the appliance again.Power supply or power cord is not connected.Connect the power supply or cord properly.When the Control Lock feature is activated, the display code CL will show on the display.Deactivate the Control Lock button.Press and hold Half Load and Energy Saver simultaneously for 3 seconds to activate or deactivate this feature.Fuse is blown or circuit breaker tripped.Replace the fuse or reset the circuit breaker.Appliance continuously beeps when the door is opened, during or right after a cycle has completed.The contents of the appliance are hot and care should be used when placing your hands inside the appliance.Close the door until the appliance and dishes have cooled down. The beeping will stop if the door is closed or the interior temperature has cooled.Water remains in sump after completion of cycle.Drain hose is kinked or clogged.Adjust hose or clear blockage.Water may remain if the power supply was lost before normal end of the course or was manually disconnected.Re-start the course.Sprays arms do not rotate smoothly.Holes of spray arms are blocked by food particles.Clean the holes of spray arms.Upper rack is crooked.Rack is poorly adjusted.See the Height Adjustable Upper Rack section.Lamps do not illuminate.Power is not connected.Connect power supply.There is excessive foam inside the appliance.Failure to use the detergent exclusive for appliance.Use the detergent exclusive for appliance.An excessive amount of rinse may cause foam.Reduce the rinse aid dispensing level.Detergent is left in the detergent dispenser.Unbalanced upper rack.Adjust the left/right height of the upper rack.Detergent may not be dispensed because poor stacking of the dishes prevent automatic opening of the detergent dispenser.Correctly arrange the dishes and always dry out the dispenser before adding new detergent so that it does not clump together.Water leaks outside the appliance.The door may not be closed due to tilted appliance. In this case a water leak may occur.Check the levelling by adjust the leg.Wrong installation of drainage hose may cause water leak.Check the connecting part of drainage hose.If the power is off, a water leak may be caused by a poor connection to the tap.Check the connection water supply hose.Drops of water forming under the sink shelf.Is there moisture accumulation under the bench top?During the automatic door opening function, high temperature steam will be emitted from the tub and will condense on the surfaces directly above the washer.Condensation that has formed under the bench top naturally evaporates and disappears after a certain period of time.However, if the bench top is made of wood or MDF, then aluminum tape must be attached to its underside at the location of the washer to prevent the timber from swelling and long term damage such as rot.

Performance

Cloudiness on glasswareCombination of excessive detergent and hard waterUse less detergent and use a rinse aid to minimize the problem.Check the setting of softening system.Black or gray marks on dishesAluminum items rubbing dishes during cycleReposition the dishes.Yellow or brown film on inside surfaces of applianceCoffee or tea stainsEliminate the stain by using a stain removal product.Yellow water remains inside the dishwasher.When initially using the appliance, Yellow water may generate in the water softener tank.This is a normal condition, and it is harmless to humans. It disappears after 1 - 3 cycles.Spots and filming on dishesWrong amount of detergent usedUse the recommended amount of detergent.OverloadingDo not overload the appliance.Improper loadingSee the OPERATION section.Insufficient water pressureWater pressure should be between 0.05 - 1.0 MPa.Insufficient detergentAdd the recommended amount of detergent. See the OPERATION section.Rinse aid dispenser is empty.Refill rinse aid dispenser.The water softener has no salt or insufficient the salt.Check whether there is the salt in the water softener.Water hardness level may be set too low.Increase the hardness level setting value.The rinse aid may be insufficient.Refill the rinse aid or increase the dispensing level.Hard water buildup in the tubRemove all dishes, cutlery basket and cutlery basket holder from appliance. Only racks should remain in tub. For best results, use citric acid powder (can be found in canning sections of most grocery stores or online). Measure 3 tablespoons (45 g) of citric acid powder. Fill main wash compartment with measured powder. If you cannot find citric acid powder, pour approximately 3/4 - 1 1/4 cups (200 - 300 mL) of white vinegar into shallow bowl and place in upper rack. Run Auto cycle. Do not use detergent. When the cycle finish, run it again.OdourThe previous cycle was stopped before completion and residual water remains in the appliance.Turn on the power, run the Cancel cycle option to remove the residual water, then run the Turbo cycle using detergent but with the appliance empty.There is food in the bottom of the unit or in the filter.Clean the filter and the interior according to the MAINTENANCE section of the owner’s manual.Unwashed dishes are left in the unit for a long time.Cycle with one cup of white vinegar in a appliance safe glass or bowl placed on the upper rack. (Vinegar is an acid, and with constant use it could damage your appliance.)Food soil remains on dishes.Improper cycle selectionSelect correct cycle based on soil level and type of dishware being washed.Water temperature is too low.Check water supply connection or water heater setting.Dishwashing detergent was not used.Use recommended detergent.Low inlet water pressureWater pressure should be between 0.05 - 1.0 MPa.Water jet holes on spray arms blocked.Clean the spray arms.Improper loading of dishes.Make sure dishes do not block spray arm rotation or interfere with detergent dispenser.Filters are clogged.Clean filters.Too much unremoved food debris on dishes.Large particles of food residues should be removed from the dishes before starting wash.

Drying

Dishes don’t dry.Rinse agent dispenser empty.Check and refill the rinse agent dispenser if empty. For better drying result, slightly open the door after operation.Tablets used may not have a built in rinse aid. This will reduce the drying performance.Change to a tablet that includes a rinse agent (contact the tablet manufacturer if unsure). Alternatively, you can use a liquid rinse agent in the dispenser if the tablets don’t have a rinse agent built in.A cycle without the Extra Dry option was selected.Select a cycle that defaults to the Extra Dry option.
