2 Connect the water supply hoses to the HOT and
COLD water faucets tightly by hand and then tighten
another 2/3 turn with pliers.
- Connect the blue hose to a cold water faucet and
the red hose to a hot water faucet.
WARNING
y Do not overtighten. Damage to the coupling can
result.
3 After connecting the inlet hoses to the water faucets,
turn on the water faucets to flush out foreign
substances (dirt, sand or sawdust) in the water lines.
Let the water drain into a bucket, and check the
water temperature.
4 Connect the hoses to the water inlets tightly by hand
and then tighten another 2/3 turn with pliers.
- Connect the blue hose to the cold water inlet and the
red hose to the hot water inlet.

damage the valves resulting in leaking and property
damage.
5 Check for leaks by turning on the faucets.
- If water leaks, check steps 1 to 4 again.
NOTE
y For your safety, and for extended product life, use
only authorized components. The manufacturer
is not responsible for product malfunction
or accidents caused by the use of separately
purchased unauthorized parts.
y Use new hoses when you install the washing
machine. Do not reuse old hoses. Use only the
inlet hoses provided with the washer. LG does not
recommend the use of aftermarket hoses.
y Periodically check the hoses for cracks, leaks and
wear, and replace the hoses every 5 years.
y Do not stretch the water hoses intentionally, and
make sure that they are not crushed by other
objects.
y Water supply pressure must be between 14.5 PSI
and 142 PSI (100 – 980 kpa). If the water supply
pressure is more than 142 PSI, a pressure reducing
valve must be installed.
y To provide optimum washing performance the hot
water temperature should be set at 120-135°F (48-
57°C) and the cold at 60°F (15°C).
