Model Version Numbers Sample
• Version 02 of the WF328 has the pump in front
• Serial (S5) May 2009 and after have the new front mounted pump ass'y.
There may be other differences, like the hoses and DD Motor.
• DC31-00054A pump is used on ALL of our washers.
• If you have a DC96-01414A pump ass'y, you can take off the pump and
use it.
Sometimes the Version change is in the field before the parts
look-up is updated. If any doubt, call GPCA

Temperatures
Location considerations
Do not install your washer in areas where water
may freeze, since your washer will always
maintain some water in its water valve, pump, and
hose areas. This can cause damage the belts, the
pump, hoses and other components. Operating
temperature should be above 60°F.
![Page 6: ##Samsung Laundry Training](https://reader036.vdocuments.mx/reader036/viewer/2022082212/55cf976f550346d033919bf4/html5/thumbnails/6.jpg)
Extended Cycle Time
Sometimes No Spin
• What 3 things cause extended time Spin
issue?
– Out of Balance – 45 min. or more, at Spin Cycle
– Over Sudsing - 1 hour or more, at Spin Cycle
– Poor Drain - up to 15 minutes for each drain
cycle
– Any other thoughts?
![Page 7: ##Samsung Laundry Training](https://reader036.vdocuments.mx/reader036/viewer/2022082212/55cf976f550346d033919bf4/html5/thumbnails/7.jpg)
Out of Balance • When the unbalance time exceeds 15 minutes during the
spin cycle, it executes the untying operation to balance
the load. It will tumble at 50 RPM and add water and
pump out twice, then generate an error (dc) the third
time. This will last about 30 minutes.
• Temperatures under 60° may cause unit not to spin and
generate an error (dc)
– See bulletin on early WF218 for software change on Main PCB
• Installation issues – Not leveled, Not locking the lock
nuts, Bending legs or frame when lifting, Shipping bolts
in place, Springs or struts broken or loose.
• Installed on slippery floor without rubber foot pads.
• Not properly locked on pedestal.
![Page 8: ##Samsung Laundry Training](https://reader036.vdocuments.mx/reader036/viewer/2022082212/55cf976f550346d033919bf4/html5/thumbnails/8.jpg)
When installing a washer and dryer on
the first or second floor, leaving this
much of the leg bolt exposed is not
recommended.
Vibration/Balance Issues
Use on slippery floors for stability.
There is one in each package, so
order 4 of them
![Page 9: ##Samsung Laundry Training](https://reader036.vdocuments.mx/reader036/viewer/2022082212/55cf976f550346d033919bf4/html5/thumbnails/9.jpg)
Washer foot damage
Floor Model sale. Washer slid
across warehouse concrete floor
Washer sliding/walking on
consumer’s concrete floor over time.
This will cause the washer to “walk” during spin cycles
and may cause a no spin condition.
![Page 10: ##Samsung Laundry Training](https://reader036.vdocuments.mx/reader036/viewer/2022082212/55cf976f550346d033919bf4/html5/thumbnails/10.jpg)

1 Tighten the lock-nut up against the base frame.
2
Put a couple of articles of clothing inside and place
paper strips under each leg. And then, put the unit
into Spin Mode as follows.
1. Power ON press SIGNAL and EXTRA RINSE for 3
seconds
2. Press the Delay Start and Silver Care Keys for 3
seconds to enter Quick Spin Test Mode.
As its speed increases, try to pull out the paper
stripes.
Notice! If you find foot-print on the paper, or the
paper is slipped out, lower the regarding leg slightly
and tighten up its lock-nut against the bottom plate.
And, repeat the test until there is no slip-out or foot-
print.
Notice! Partial circle footprint on paper could
indicate a bent leg or frame.

Over Sudsing
ALWAYS USE HE Detergents
• When using the proper amount of
detergent in soft water with “clean”
clothes, it is possible to get oversudsing.
• Unless clothing is “dirty”, in soft water use
½ or less of the recommended detergent.
![Page 12: ##Samsung Laundry Training](https://reader036.vdocuments.mx/reader036/viewer/2022082212/55cf976f550346d033919bf4/html5/thumbnails/12.jpg)
Over Sudsing Example 1
Consumers wash “clean” clothes in soft
water, no “soil” for the detergent to hold
in suspension, creating over sudsing.
![Page 13: ##Samsung Laundry Training](https://reader036.vdocuments.mx/reader036/viewer/2022082212/55cf976f550346d033919bf4/html5/thumbnails/13.jpg)
Over Sudsing Example 2
![Page 14: ##Samsung Laundry Training](https://reader036.vdocuments.mx/reader036/viewer/2022082212/55cf976f550346d033919bf4/html5/thumbnails/14.jpg)
Small puddle under the drawer usually means over sudsing
Over Sudsing Example 3
![Page 15: ##Samsung Laundry Training](https://reader036.vdocuments.mx/reader036/viewer/2022082212/55cf976f550346d033919bf4/html5/thumbnails/15.jpg)
Even when using
the recommended
“HE” detergent, if
too much
detergent is used
suds will be
created.

A fault is detected in the water level sensor. Data
(frequency) shows the water level is at or above the

Troubleshooting Tips
• Liquid detergent seeping from main wash
cup into prewash
• Leak at Detergent Drawer
• Pump Noise
• Intermittent stopping in cycle
• Siphoning faults
• Fabric Softener Dispensing
• Steam Operation
![Page 21: ##Samsung Laundry Training](https://reader036.vdocuments.mx/reader036/viewer/2022082212/55cf976f550346d033919bf4/html5/thumbnails/21.jpg)
Liquid detergent seeping from main wash cup into prewash after filling cup is
normal and is necessary by design to prevent water standing in cup when cycle is
complete. This will not effect normal operation and some of the detergent will enter
during prewash, selections without prewash will see no difference. If the customer
wants to use the pre wash option recommend using a powder detergent.
Notice the notch in between the arrows.
This allows water to bleed out of cup
after dispensing preventing cup from
being full of water after cycle.

clogged with power
detergent due using
too much or wrong

The hose from the

may be clogged with
various items. Bleach or
detergent caps may act like
butterfly valves and cause
intermittent leaking from

1) Place the Assy-Pump Drain into the
unit.
2) Insert the pump cushion into the
opening at the base of the unit.
3) Once the pump cushion is inserted
into the opening slide the assembly
forward to lock.
4) After the Assy-Pump is locked in
place secure the pump bracket to
the base of the unit.
If the Assy-Pump is installed without placing the
pump cushion into the opening at the base of
the unit. The filter assembly will hit against the
metal bracket at the front of the unit, causing
the pump assembly to make noise.

Water Fill WATER PRESSURE - 7.25 to 116 PSI
On the large capacity washer models the water pressure requirements are 20 to 116 PSI
Depending on the washer model there may be a 2, 3 or 4 valve assembly for the
cold water. There is always only one hot water valve.

Drain Pump Changes
Older drain pump – mounted
in the rear of the machine.
No clean out plug. Found in the
2006 and 2007 models.
New drain/circulation pump mounted
in the front of the machine. Clean out plug
and water release hose to empty the tub.
Found in the 2008 models WF338/448
that have the steam feature.

Troubleshooting the Drum Motor
The red, white and blue wires go directly from
CN5* to the stator of the drum motor.
Motor Windings Check:
Resistance at Pin # 1 and # 2 of CN5 = ~ 12Ω
Resistance at Pin # 1 and # 3 of CN5 = ~ 12Ω
Resistance at Pin # 2 and # 3 of CN5 = ~ 12Ω

Testing the Water Valves
Water Valve Check
Check the Voltage at Pin #1 of CN2 and Pin #1, 2, 7, 8 and 9 of CN3
When each valve operates the measured voltage is 120VAC When checking the resistance of the water valve solenoids they should all measure ~ 1200-

the Drain Pump: Should be ~14 Ω
1. Unplug the unit.
2. Remove Back Cover.
3. Remove the wire connector.
4. Remove Clamp and Drain Hose.
5. Remove Clamp and Pump Hose.
6. Remove the bolts (3 - 13mm) securing Drain
Pump to Cabinet Bottom.
7. Remove the screw securing Drain Pump to
the support bracket. Twist Drain Pump
clockwise to remove.
** Make sure to put an empty container under
Drain Pump to catch the water still inside
the pump.

Drain Pump Error
This is a typical error indicating a drain error but not necessarily a drain pump error.
Items that should be checked to correct drain errors are:
• Connections
• 120VAC from the main board to the pump motor
• Pump motor resistance
• Restriction in the pump or drain hose

After checking for 120VAC on the connectors and checking the wiring harness,
remove the connectors from the valves and measure the resistance of the
solenoid coils. A good valve solenoid will measure approximately 1.5 kΩ

Sensor Bar Touch Data Mode
Press Temp + Signal for 3 seconds during the drying cycle (same for all
Frontier models). When there are wet items being dried, data will change
from 0 to 1200 as the wet clothes touch the sensor bars. This procedure
checks the moisture sensor bars ability to detect moisture. If the readings do
not change with wet clothes inside, check the sensor bars.
