• 01 • • 02 •
GROUNDING INSTRUCTIONS
• This dishwasher must be grounded. In the event of a malfunction or breakdown, grounding
will reduce the risk of electrical shock by providing a path of least resistance for the electric
current. This dishwasher is equipped with a cord with a grounding conductor and a
grounding plug. DO NOT, under any circumstances, cut or remove the grounding plug from
the power cord.
• The plug must be plugged into an outlet that has been installed and grounded in
accordance with all local codes and ordinances.
• Improper connection of the grounding conductor can result in risk of electrical shock.
• Check with a qualified electrician or service representative if you are unsure as to whether
the dishwasher is properly grounded. Do not modify the plug provided with the dishwasher.
If it does not fit the outlet, have a qualified electrician install a proper outlet.
ELECTRICAL REQUIREMENTS
Look at the rating label for the voltage rating (120 V) and connect the dishwasher to the
appropriate power supply. If the supply cord is damaged, it must be replaced by the
manufacturer, service agent, or a similarly qualified person in order to avoid any hazards.
ELECTRICAL CONNECTION
Ensure that the voltage and frequency of the dishwasher corresponds to those on the rating
plate. Only insert the plug into an electrical socket that is grounded properly. If your electrical
sockets are not appropriate for the plug, replace the sockets rather than using an adapter.
GETTING TO KNOW YOUR DISHWASHER
IMPORTANT: To get the best performance from your dishwasher, read all operating
instructions for the dishwasher prior to first use.

Connecting the Drain Hose to a Sewer
1. There are three options for sewer connection, A (sink), B (sink drainpipe), and C (drainage
pipe). For options B and C, it is required to drill a hole on or under the counter so that the
pipe can go through the counter.
2. The drain hose must be property fitted to its containment source (such as a sink, bucket,
etc.) to avoid water leaks. Ensure that the drain hose is not kinked or impeded in any way.
Adding Water to Dishwasher
NOTE: This machine supports two water supply modes, including faucet mode and
water tank mode .
Faucet Mode
1. Remove the silica gel plug from the water inlet on the back of the machine. Then, attach
one end of the water inlet hose onto water inlet of the machine.
2. Connect the other end of the water inlet hose to your faucet and make sure it is fastened
tightly in place. The included water inlet hose has a 3/4" GHT female connector, so it
matches the faucet with a 3/4" GHT male connector.
NOTE: If the included water inlet hose does not fit your faucet, you may need to buy a
3/4" GHT threaded faucet adapter from a plumbing supply manufacturer. If you are
unsure of what to do, please feel free to contact our after-sales service team.
3. Turn on the dishwasher and press the Mode button to choose a wash cycle. Then, press
the Start/Pause button to start the wash cycle. The panel will display a white indicator ,
meaning the faucet is properly connected and turned on.

NOTES:
1. While in the faucet mode, DO NOT disconnect the faucet. Otherwise, the wash cycle
cannot be completed.
2. A red flashing water shortage indicator means that this machine is not connected
to a faucet, the faucet is not turned on, and/or the water tank is not full. If the water tank is
full, the panel will display a white indicator .
Water Tank Mode
Reminder: If the machine is being used for the first time or has not been used in a long time,
insufficient water flow may occur when the water tank is filled due to trapped air in the
machine’s water pipe system, which prevents the water from flowing into the machine
interior. In this case, you can slightly shake the machine 5-6 times to exhaust all trapped air.
This will ensure a smooth water flow.
1. Open the water tank lid and fill with about 1.3 gallons (5 L) of water, or approximately 3
pitchers. When the tank is full, beeps will be heard. There is no need to add more water
during the washing process.
NOTE: To prevent loss of the tank lid, attach it to the water tank.
2. If the water tank is not full when you start a wash cycle, a red flashing water shortage
indicator will display on the panel and the buzzer will beep. When the water tank is
full, a white water tank mode indicator will appear.
3. Before starting any wash cycle, if the machine detects that the water tank is full, it will
automatically switch to the water tank mode.
4. To drain the water tank by hand, pause the wash cycle and press and hold both the Dry
button and Power button simultaneously for 3 seconds. If the water tank will not be used
for a long time, it is recommended to empty the water tank.
5. The system will automatically check all water supplies. If the red water shortage indicator
appears, you will need to fill the water tank or turn on the faucet. Once the water tank is filled,
the machine will automatically start the wash cycle you selected with no need to press the
Start/Pause button again. In the faucet mode, it is required to press the Start/Pause button
again to start the wash cycle after you open the faucet.
NOTE: In the case of a water shortage, if you press the Start/Pause button 5 times and
there is still no adequate water supply, the machine will automatically enter standby mode.
Or, if there is no user operation or water supply for 10 minutes, the machine will automatically
enter standby mode.

CLEANING & MAINTENANCE
Filter System
NOTES:
• Never run the dishwasher without the filters in place. Improper placement of the filters may
reduce the performance level of the dishwasher and damage dishes and utensils.
• Make sure the filters are properly assembled.
• The entire filter system should be cleaned once a week. Remove food remnants and clean
the filters under running water.
• When cleaning the filters, do not knock them against surfaces. This can contort the filters
and affect the performance of your dishwasher.
The filters prevent larger remnants of food or other objects from getting inside the pump.
For best performance and results, regularly clean the filter system.
The filter system consists of a coarse filter, a flat filter (main filter), and a micro filter (fine filter).
① Coarse filter: This filter traps larger items, such as pieces of bone or glass that could block
the drain.
①
③
②
② Fine filter: This filter catches soil and food residue in the cylindrical base and prevents the
soil from being redeposited on the dishes during wash cycle.
③ Main filter: Food and soil particles trapped by this filter are broken down by a special jet on
the spray arm and flushed down the drain.
To Remove the Filter System
1. Turn the fine filter counterclockwise to remove it from the machine.
2. Push the tabs at the bottom center of the fine filter to separate the coarse filter from the
fine filter.
3. Remove the main filter by pulling upwards.
To Clean the Filter System
1. Rinse the filter system under running water. Use a soft cleaning brush to clean the coarse
filter and the fine filter.
2. To reinstall the filter system, position the main filter on its seat and push downwards, align
the tabs on the bottom of the coarse filter with the corresponding hole of the fine filter,
and then insert the coarse filter into the fine filter. Then, place the fine filter into its seat
and rotate clockwise to tighten.

Dishwasher Care and Maintenance
Daily Maintenance
• The control panel and exterior should be cleaned by using a lightly damp cloth. After
cleaning, make sure to dry thoroughly. Never use sharp objects, scouring pads, or harsh
cleaners on any part of the dishwasher. To remove spots or stains from the surface of the
interior, use a cloth dampened with water and a little vinegar.
• There may be some oil stains left on the edge of the dishwasher’s interior wall or door after
heavily soiled loads have been washed. To clean the edge around the door, only use a soft,
warm, damp cloth. Avoid getting water inside the door lock and electrical components.
• Regularly clean the door seals with a damp sponge to prevent odors from trapped food
particles in the door seal.
WARNING: Never use a spray cleaner to clean the door panel, as it may damage the door
lock and electrical components. Abrasive agents or paper towels should not be used due to
risk of scratching or leaving spots on the stainless-steel surface.
Protecting the Dishwasher from Freezing
Please take frost protection measures during the wintertime. After every wash cycle, take
the following steps:
1. Turn off the dishwasher. Cut off electrical power from the dishwasher.
2. Turn off the water supply and disconnect the water inlet hose from the back of the unit.
3. Drain the water from the inlet hose and inlet port (Use a pan or bucket to catch the water).
4. Reconnect the water inlet hose to the inlet port.

area.
If your dishwasher no longer works due to freezing or ice, please contact our after-sales service team.
General Tips
In order to keep your dishwasher in good working order, the following suggestions should be
observed:
• Before cleaning or performing maintenance, always remove the plug.
• After every wash - Turn off the water supply to the appliance and leave the door slightly
ajar so that moisture and odors are not trapped inside.
Spray Arms
The upper and lower spray arms can be easily removed for periodic cleaning of the nozzles,
preventing potential clogging. Wash them under running water and carefully replace them in
their seats, checking that rotary movement is in no way impeded.
To Remove and Clean the Spray Arms
1. Open the door and take out the basket.
2. Remove the lower spray arm by grasping the middle arm and pulling upwards. Unscrew the
upper spray arm by rotating counterclockwise.
3. Wash the arms under running water and brush each spray arm. Use tools with a sharp
point, such as a needle, to clean nozzles if needed.
4. Replace the lower spray arm to its seat by pushing downward until it clicks into place.
Replace the upper spray arm by screwing clockwise into its seat. Ensure that the spray arm
movement is not impeded before running another cycle.

• If the dishwasher will not be used for an extended period of time - It is recommended
that you run a wash cycle with the dishwasher empty, then power off the dishwasher,
remove the plug from the socket, turn off the water supply, force drain the water tank, and
leave the appliance door slightly open. This will help the door seals to last longer and
prevent odors.
• Moving the appliance - If the appliance must be moved, try to keep it in a vertical position.
Do not transport the unit on its side or upside down.
• Water connection - Our water hose has a 3/4" GHT female connector, so it matches with
faucets with a 3/4" GHT male connector. Connect the female connector to your faucet and
make sure it is fastened tightly in place. Please Note: If the supplied water inlet hose does
not fit your faucet, you may need to buy a 3/4" GHT threaded faucet adapter from a
plumbing supply manufacturer. If you are unsure of what to do, please feel free to contact
our after-sales service team.
• Water drainage - The drain hose must be properly fitted to avoid water leaks. Ensure that
the water drain hose is not kinked or in any way impeded. If the sink is higher than the
surface where you have placed your dishwasher, it will be necessary to drain excess water
into a bucket that is in a lower position than the dishwasher. If you need a drain hose
extension, be sure to use a similar drain hose, and that it is no longer than 12 feet long.
Otherwise, the cleaning effect of the dishwasher could be reduced.
