Dryer Rack Installation Instructions
Open the door.
Hold the dryer rack
with both hands.
Put the dryer rack into
the drum
Check and be sure that the
front of the rack is properly
seated behind the lint filter.

Use the instructions under option 1 if your home
homehas a 4-wire receptacle (NEMA type 14-30R).
Use the instructions under option 2 or 3 if your
home has a 3-wire receptacle (NEMA type 10-30R).
Use option 2 if local codes and ordinances permit
the connection of a chassis ground to the neutral
connector. If this is not permitted, use option 3.
4-wire receptacle
Review the following options to determine
the appropriate electrical connection for
your home:
(NEMA type14-30R)
(NEMA type10-30R)
3-wire receptacle
1. Connect the neutral wire (white) of the power
cord to the center terminal block screw.
2. Connect the red and black wires to the left and
right terminal block screws.
3. Connect the ground wire (green) of the power
cord to the external ground screw. Remove the
neutral ground wire of appliance and connect it to
center screw.
4. Make sure that the strain relief screw is tightened
and that all terminal block nuts are tight and the
power cord is in the right position.
• If your local codes or ordinances do not allow the
use of a 3 wire connection, or you are installing
your dryer in a mobile home, you must use a 4-
wire connection.

lf your local codes or ordinances permit the
connection of a frame-grounding conductor to the
neutral wire, use these instructions. If your local
codes or ordinances do not allow the connection of
a frame-grounding conductor to the neutral wire,
use the instructions under Section 3: Optional
3-wire connection.
1. Connect the neutral (white or center) wire (B) to
the center, silver colored, screw (A) and tighten
securely.
2. Connect the other two power cord wires (red and
black) to the left and right terminal block screws
and tighten securely.
3. Tighten the strain relief screws (C) securely.

For further assistance, refer to section on Gas Requirements.
1. Make certain your dryer is equipped for use with the
type of gas in your laundry room. Dryer is equipped
at the factory for natural gas with a 3/8” N.P.T. gas
connection.
3-2. Connect Gas Supply Pipe (Gas Dryer ONLY)
2. Remove the shipping cap from the gas connection
at the rear of the dryer. Make sure you do not
damage the pipe thread when removing the cap.

5 3/8” N.P.T. Gas Connection
3. Connect to gas supply pipe using a new flexible
stainless steel connector.
4. Tighten all connections securely. Turn on gas and
check all pipe connections (internal & external) for
gas leaks with a non-corrosive leak detection fluid.
5. For LP (Liquefied Petroleum) gas connection, refer
to section on Gas Requirements.

• The steam feeder must be filled with water up to the MAX line. Otherwise, an error message
will be displayed.
•If the lint filter or exhaust duct is clogged, the Steam options will not give proper results.
•For best results, load articles of similar size and fabric type.
Do not overload.
•Water only - Do not add any additives or other materials as these will damage your dryer.
•Before moving the dryer, make sure the steam feeder is empty.
•Best results are obtained with cotton/poly blend fabrics.

8-2. Troubleshooting for Steam Dryer
PROBLEM
ADD WATER indicator
light is on during the
drying cycle
•Water supply error.
•This is normal. •This is steam condensation. The dripping water
will stop after a short time.
•Water level error. •Unplug dryer and call for service.
•Too many or to different
types of garments in
dryer.
•Small loads of 1 to 5 items work best.
•Load fewer garments. Load similar-type garments.
•The function of this cycle
is to remove wrinkles
from fabric.
•Use an iron to make creases.
•This is normal. •Depends on individual moisture level in skin.
•Correct drying options
not selected.
•Select load weight manually before starting
REDUCE STATIC option.
•This is normal. •Depends on the amount or type of garments.
•This is normal. •This is steam condensation on door surface.
Water drips from
orifice when Steam
Cycle starts.
Steam doesn’t
generate but no error
code is shown.
Garments still
wrinkled after
STEAM FRESH™.
There are no creases
left on garment after
STEAM FRESH™.
Garments have
static after REDUCE
STATIC.
Garments are too
damp or too dry after
REDUCE STATIC.
Garments are not
uniformly damp after
EASY IRON.
Water drips from door
during Steam Cycle.
•This is normal. •Steam vapor is difficult to see when the door is
closed.
Steam is not visible
during Steam Cycle.
•This is normal. •The drum is turned off so that the steam vapor
remains in the drum.
Drum does not turn
during Steam Cycle.
POSSIBLE CAUSES
•Check steam feeder drawer:
(1) Make sure steam feeder is filled with water to
MAX line.
(2) Make sure steam feeder is seated properly
and drawer is fully closed.
(3) Turn the dryer off then restart the Steam cycle.
•Do not use distilled water; the water level sensor in
steam generator will not work.
•Pump not working. Unplug dryer and call for service.
SOLUTIONS

PROBLEM
•This is normal. • Steam is released at different stages of the cycle
for each option.
Cannot see steam

beginning of cycle.
•MORE TIME button

•Pressing the MORE TIME button several times will
set the cycle for a large load such as a comforter.
The display shows

9FLOW SENSOR FUNCTION
This FlowSenseTM function detects the clogging or blocking of ducts.
Clogged duct vents or hoses decrease efficiency in drying clothes. Clogged vents can also cause fire.
This function alarms you, when to clean the ducts.
When the alarm about duct clogging is on display of the panel, your duct vents should be cleaned by
yourself or serviceman.
