1-1. Safety Instructions for Service Engineers
Make sure to observe the following instructions to operate the product correctly and safely and prevent possibleሪ
accidents and hazards while servicing.
Two types of safety symbols, Warning and Caution, are used in the safety instructions.ሪ
Warning Hazards or unsafe practices that may result in severe personal injury or death.
Caution Hazards or unsafe practices that may result in minor personal injury or property damage.
Warning
Before Servicing
(When servicing electrical parts or harnesses) Make sure to disconnect the circuitࣃ
breaker or power cable before servicing.
Failing to do so may result in a risk of electric shock.¯
Do not allow consumers to connect several appliances to a single power outlet at the
ࣃ
same time.
There is a risk of fire due to overheating.¯
When removing the power cord, make sure to hold the power plug when pulling the plugࣃ
from the outlet.
Failing to do so may damage the plug and result in fire or electric shock.¯
When the dishwasher is not being used, make sure to disconnect the circuit breaker orࣃ
power cable from the power outlet.
Failing to do so may result in electric shock or fire due to lightning.¯
Do not place or use gasoline, thinners, alcohol, or other flammable or explosiveࣃ
substances near the dishwasher.
There is a risk of explosion and fire caused from electric sparks.¯

1-2
1. Safety Instructions
While Servicing
Check if the power cable is damaged, flattened, cut or otherwise degraded.ࣃ
If faulty, replace it immediately.¯
Failing to do so may result in electric shock or fire.
Completely remove any dust or foreign material from the housing, wiring and connection
ࣃ
parts.
This will prevent a risk of fire due to arcing and short circuits in advance.¯
When connecting wires, make sure to connect them using the relevant connectors and
ࣃ
check that they are completely connected.
If tape is used instead of the connectors, it may cause fire due to arcing.¯
Make sure to disconnect the PBA power terminals before starting the service.
ࣃ
Failing to do so may result in a high voltage electric shock.¯
When replacing the heater, make sure to fasten the nut after ensuring that it is inserted
ࣃ
into the bracket-heater.
If not fasten the nut of the heater, it cause water and electric leakage.¯
After Servicing
Check for any water leakage.ࣃ
Perform a test run for the dishwasher using the standard(normal) cycle and check¯
whether there is any water leakage through the floor section or the pipes.
Do not allow consumers to repair or service any part of the dishwasher themselves.
ࣃ
This may result in personal injury and shorten the product lifetime.¯
If it seems that grounding is needed due to water or moisture, make sure to runࣃ
grounding wires.
Failing to do so may result in electric shock due to electric leakage.¯

1-3
1. Safety Instructions
Caution
Before Servicing
Do not sprinkle water onto the dishwasher directly when cleaning it.ࣃ
This may result in electric shock or fire, and may shorten the product lifetime.¯
Do not place any containers with water on the dishwasher.
ࣃ
If the water is spilled, it may result in electric shock or fire. This will also shorten the¯
product lifetime.
Do not install the dishwasher in a location exposed to snow or rain.ࣃ
This may result in electric shock or fire, and shorten the product lifetime.¯
Do not press a control button using a sharp tool or object.ࣃ
This may result in electric shock or damage to the product.¯
During Servicing
When wiring a harness, make sure to seal it completely so no liquid can enter.ࣃ
Make sure that they do not break when force is exerted.¯
Check if there is any residue that shows that liquid entered the electric parts or
ࣃ
harnesses.
If any liquid has entered into a part, replace it or completely remove any remaining¯
moisture from it.
If you need to place the dishwasher on its back for servicing purposes, place a support(s)
ࣃ
on the floor and lay it down carefully so the back is on the floor.
Do not lay it down on its front or side. This may result in scratches to the surface or¯
damage to the parts.

1-4
1. Safety Instructions
After Servicing
Check the assembled status of the parts.ࣃ
They must be the same as before servicing.¯
Check whether the product is level with the floor. Check if there are any deformations in
ࣃ
the sink. Check that the dishwasher is firmly installed to the sink.
Vibrations can shorten the lifetime of the product.¯

Features Description Remarks
Extra large capacity
The upper rack is slanted for larger dishes. The spaceሪ
has been maximized to accommodate a variety of dish
sizes.
Elegant design with digital
touch sensors
Digital touch sensors are used in the control panel for moreሪ
simple operation, with a touch of elegance.
Increased convenience
The smart auto cycle determines the level of soil on theሪ
dishes and initiates the optimal cycle using this feature
saving water, energy and time.
Extremely quiet operation
Efficient noise control technology is used for the quietestሪ
possible operation. Your new Samsung dishwasher will be
quieter than ever.
Self-cleaning filter
Cleaning the filter yourself is a thing of the past! This productሪ
keeps food waste internally while operating, then drains it
automatically with the water.
Storm wash
(For DMT800 & DMT700
series)
With a jet stream like a geyser, Storm Wash effectivelyሪ
cleans big, heavily soiled pots with ease. Look for the built-in
extra nozzle and spray in the specialized Storm Washing
Zone.
Twin fan condensing drying
Two fans connected to one motor make for better dryingሪ
performance. Still better, your dishwasher emits no hot
steam. Instead, it mixes external fresh air with the internal
hot steam during drying to eliminate the steam, making your
dishwasher safer and easier to use.
