Changes

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

Model Version Numbers

0001 = 02

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.

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?

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.

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

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.

No Description Image

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.

Washer Vibration Testing

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.

Over Sudsing Example 1

Consumers wash “clean” clothes in soft

water, no “soil” for the detergent to hold

in suspension, creating over sudsing.

Small puddle under the drawer usually means over sudsing


Even when using

the recommended

“HE” detergent, if

too much

detergent is used

suds will be

created.

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

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.

Detergent Drawer Leaks

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.

2. Once in Continuous Run Mode, 7-Segment will toggle display “cc” and the

remaining time.

3. The previous cycle will restart during Continuous Run Mode until continuous run

mode is disabled.

4. During Continuous Run Mode, press Signal + Dryness Level for 3 seconds to

return to normal user mode 7-segment will no long display “cc” and only

display the remaining time.

Water Valve Troubleshooting

The Water valves can be tested by

measuring the output voltage at the

connector. This should measure 120VAC

Main Board

What may seem like a water valve problem may be a

clogged spray nozzle. Dirt or mineral build up can clog

t h e n o z z l e a s i t h a s a v e r y f i n e o p e n i n g

70


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

How to Enter:

Start Dryer tumbling, Press Temp + Signal for 3 seconds during the

drying process (same for all Frontier models.)

Open door, touch both sensor bars with wet cloth,

sensor hit numbers show in display. Note: Test subject to change without notice

DV448 Service Mode

Continuous Run Mode

1. Press Dry Level + Signal for 3 sec during Power On State (normal user mode).

2. Once in Continuous Run Mode, “total cycle” and the remaining time will blink in

the display.

3. The previous cycle will restart during Continuous Run Mode until the mode is

deactivated.

4. During Continuous Run Mode, press Dry Level + Signal for 3 seconds to go

back to normal user mode, “total cycle” will go off and the remaining time will

stop blinking and the cycle will complete.

DV448 Service Mode

System check mode

Special test mode:

While in Power Off, pressing the Dry Level + Power buttons simultaneously

will put the dryer into the System Check mode “t2” will display.

System Check Mode Progress in the t2 mode function turns on the Motor

(CW) relay, turns the Heater relay on and off, Motor (CW) Relay Off

79

Special Test Mode

To enter Service Mode, press Temp + Signal for 3

seconds, or until it sends out a beeping sound 3 times.

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.
