ESD NOTICE
Some of the electronic in appliances are electrostatic discharge (ESD)
sensitive. ESD can weaken or damage the electronics in these appliances
in a manner that renders them inoperative or reduces the time until their
next failure. Connect an ESD wrist strap to a ground connection point or
unpainted metal in the appliance. Alternatively, you can touch your finger
repeatedly to a ground connection point or unpainted metal in the
appliance. Before removing a replacement part from its package, touch the
anti-static bag to a ground connection point or unpainted metal in the
appliance. Handle the electronic control assembly by its edges only. When
repackaging a failed electronic control assembly in an anti-static bag,
observe these same precautions.

Features
LARGE CAPACITY
The larger drum (4.0 cu. ft.) allows washing of
larger (heavier) loads and oversized items
(comforters, curtains, blankets, etc.) There is less
wrinkling and tangling of the laundry.
DIRECT DRIVE
The brushless DC motor drives the drum directly
WM2688H*M Steam Washer Training
without belts, pulleys, or transmissions. The
maximum spin speed of 1,320 RPM extracts more
water from the laundry, reducing drying times.
TILTED DRUM/LARGE DOOR
The tilted drum (10°) and large door opening allow
easier loading and unloading.

Features (continued)
STEAM WASHING/SteamFresh®
The steam feature works with the recirculating pump to
increase washing performance while maintaining low energy
and water usage. SteamFresh® removes wrinkles from dry
clothes.
ROLLER JETS and BALLS
The baffles pick up water as the drum turns and allow it to
pour through the clothing as it tumbles. The balls enhance
the washing performance while maintaining fabric care.
AUTOMATIC LOAD DETECTION
The microprocessor reads the current required to turn the
drum and determines the weight of the load. This input is
used to make numerous decisions during the wash cycle.

BUILT-IN HEATER
The internal heater helps maintain the water at
its optimal temperature for selected cycles.
The SANITARY cycle kills most common germs
and bacteria.
CHILD LOCK
This allows the user to lock the controls. Children
then cannot play with the buttons and disturb the
WM2688H*M Steam Washer Training
wash cycle.
REMOTE LAUNDRY MONITOR

Serial Number Identification
The serial number is
unique to each product.
It gives information
concerning the time and
place of manufacture. The
serial number is required to
be paid for warranty
service and to get the
correct part in the event a
running production change
was made. Some models
may have four (4) letters
instead of two (2) for the
product code number. The
third and fourth letters are
significant only to the
manufacturing facility.

Fuzzy Logic
To get the best washing performance, the user selects one of the standard
cycles. Sensors in the COMBO make an infinitely variable number of
adjustments as the cycle progresses. Adjustments are automatically made
for load size, incoming water temperature, soil level, rinses required, and
other variables.

Door Lock
The door has an automatic, electrically operated lock system. When the
machine is off or paused, the door can be opened by pulling it. When the
machine is operating, the electric latch keeps the door closed.
The door cannot be opened:
•When the COMBO is operating
•When the power failed or the washer is unplugged
(until the capacitor discharges and releases the lock)
•When the DOOR LOCK light is on
•When the drum is still turning

DOOR LOCKED LAMP
The DOOR LOCK lamp lights:
• When the COMBO is operating
• When the water level sensor frequency is lower than 22.9 kHz
• When the temperature inside the tub is over 45° C (113°F)

Water Circulation
The recirculation pump circulates the water during most of the cycle.
During the WASH cycle, it runs continuously for the first 3 minutes and
then intermittently throughout the cycle. During the RINSE cycle, it runs
continuously as soon as the appropriate amount of rinse water has been
added. This recirculated water enters the drum at the top of the door at a
small shower head. This spray not only keeps the window and gasket
clean, it allows the clothes to be soaked with detergent or rinse water more
quickly and can be used to control an oversudsing event.

Water Recirculation
The recirculation pump is separate
from the drain pump, but they are
attached to opposite sides of the filter
housing.
The steam is not pumped; it comes
into the washer drum under its own
pressure. When steam or the sanitary
cycle is used, the door will remain
locked until the laundry has cooled to
WM2688H*M Steam Washer Training
a safe temperature.
The pumps and filter are located at
the bottom left front corner. The filter
can be unscrewed, cleaned, and
replaced.

Water Circulation
Use the small drain hose to
evacuate the water
remaining in the bottom of
the tub before removing the
filter.
The drain pump is on the
left and exhausts the water
via the gray corrugated
hose.

The recirculating pump is
on the right and recirculates
water from the tub to the
shower spray at the top of
the door gasket via the
smaller black hose.

Air Vent
The air vent on the back of the machine must be left open and clear at all
times.
If the washer is installed in a closet or closed laundry alcove, there must be
sufficient clearance and ventilation. The closet should have a full louvered
door with at least 800 square inches (0.5 m2) of open area for ventilation.
The washer requires a space of at least 1 inch (2.5 cm) between the wall
and the machine on each side and at least 4 inches (10 cm) between the
back of the washer and the wall.
Additional space may be needed for servicing.

Accessories
The washer comes with the two input hoses. The blue stripe is for cold
water and the red stripe is for hot water. While the hoses are mechanically
identical, it is critical to the performance of the washer to have the hot and
cold hoses connected correctly.
The wrench is used to remove (and replace) the shipping bolts and to
adjust the leveling feet. Be sure to leave it and encourage the customer to
retain the wrench, the four shipping bolts, and the manual in a safe place
in the event the washer requires service or the customer moves.
The shipping bolts MUST BE REMOVED before operating the washer.

install the modem on the
back of the dryer.
Save the small socket cover
and screws in the event you
need to remove the modem
for some reason. The
socket should be covered at
