DIAGN STIC SYSTEM – FFL(E/G)3911QW and FFL(E/G)4033QW (Washer)

This information is intended for Qualified Technicians Only.

CAUTION: DISCONNECT ELECTRICAL POWER BEFORE SERVICING

1 Diagnostic Mode

This mode is used in several conditions:

•In factory assembly line to perform a manual test of the machine functionality (final

assembly test).

•By service to check for faults and repair the machine.

•In the labs to check the machine functions.

2 Entering Diagnostic Mode

1. Set the cycle selector to pre-soak on both models (near 9 o’clock position) and the temperature

knob at the far left CCW position (hot for both models). The other knobs and switches do not

matter.

2. If the unit is not plugged in, plug in and skip to step 6 or do a full control reset as in steps 3 to 5.

3. Hold the selector knob for 6 to 8 seconds and within 5 seconds complete steps 4 and 5.

4. Move the temperature knob to the far right position CW and push the selector knob

momentarily (<1 second)

5. The unit will indicate a full control reset by beeping 3 times, then move the temperature

knob to the far left CCW position (hot for both models)

6. Within 5 seconds complete the following to enter diagnostic mode.

7. Move the temperature knob to the far right CW position and push the selector knob momentarily

(<1 second)

8. Move the temperature selector to the far left CCW and push the selector knob momentarily (<1

second)

9. There will be a long beep signalling the entry into diagnostic / line test mode, if not start over with

an effort to perform the series faster or with more precision.

3 Diagnostic Program Definition

1. Cycle Selector knob in the Normal position 12 o’clock is the zero position where the switches can be

checked.

2. Turn the Cycle Selector knob (1) click clockwise from Normal position.

•The lid lock will activate and the hot water solenoid will activate and hot water shall enter the

tub.

•Note: Clutch actuator starts rotating to find the "disengaged" position, when there it stops.

3. Turn the Cycle Selector knob (2) clicks clockwise from Normal position.

•The cold water solenoid will activate and cold water shall enter the tub.

•Note: Clutch actuator rotates to find the "disengaged" position, when there it stops.

4. Turn the Cycle Selector knob (3) clicks clockwise from Normal position.

•The lid lock will deactivate and the lid can be opened.

5. Turn the Cycle Selector knob (4) clicks clockwise from Normal position.

•The lid lock will activate and both the hot and cold water solenoids will turn on and fill up to a

certain level. After the Pressure Sensor has been satisfied, agitation will begin.

•If softener option is available on the machine, then the softener solenoid will also activate and

the softener compartment will be filling up and siphoning cold water at the same time.

6. Turn the Cycle Selector knob (5) clicks clockwise from Normal position.

•The drum will stop and the drain pump will activate, draining out any water in the tub.

•After draining the clutch actuator will start moving continuously, for about 1 minute

7. Turn the Cycle Selector knob (6) clicks clockwise from Normal position.

•The Drain Pump turns on until no water is detected on the sensor, the clutch actuator rotates

to find the "engaged" position

•The Drain Pump turns off just before the drum starts its rotation to a high speed spin.

8. Turn the Cycle Selector knob (7) clicks clockwise from Normal position.

•The control will signal the last 3 error codes. Press the cycle Selector to scroll through them.

(See the part about reading error codes)

•Press and hold the selector knob for at least 5 seconds in this position to clear the alarm

history.

4 Exiting Diagnostics Mode

Any one of the following methods may be used to exit DM:

•Disconnect power and wait 5-8 seconds then reconnect power.

•Press and hold the knob for at least 5 seconds in selector position modes 1 to 6 CW.

•The machine exits diagnostic mode after 15 minutes of no UI activity.

N TE

The machine configuration for electrical test mode at the next power on after diagnostic mode, is not

active. So it is not necessary to power off the machine again.

1 User Interface Test

Selector position: Position 0, 12 o’clock, top center, the normal wash position

Purpose of test: Function of switches and buzzer.

Activated components: Buzzer with a switch change

UI behaviour Change switch positions and the buzzer beeps

Working conditions: Drum stopped, door unlocked

2 Hot Water Valve Test

Selector position: Turn 1 click clockwise from the top.

Purpose of test: Water loading from the hot water valve.

Activated components: Door lock, hot water valve, clutch motor

UI behaviour None

Working conditions: Door locked, water level lower then 140mm, for max. 5 minutes. The clutch

moves to the agitate position, if it was in spin.

3 Cold Water Valve Test

Selector position: Turn 2 clicks clockwise from the top.

Purpose of test: Water loading from the cold water valve.

Activated components: Door lock and cold water valve, clutch actuator

UI behaviour None

Working conditions: Door locked, water level lower then 140mm, for max. 5 minutes. The clutch

moves to the agitate position, if it was in spin.

4 Door Lid Unlock Test

Selector position: Turn 3 clicks clockwise from the top.

Purpose of test: Deactivate the door lock.

Activated components: Door lock.

UI behaviour None

Working conditions: Drum stopped

Page 4 of 11

5 Three Water Valves Test

Selector position: Turn 4 clicks clockwise from the top.

Purpose of test: To test both hot and cold and, if present, softener water valves and the

softener siphon drains fully, agitate function.

Activated components: Door lock, three water valves, main motor

UI behaviour None

Working conditions: Door locked, Add while water level lower than 55mm, for max. 5 minutes.

The clutch moves to the agitate position, if it was in spin. Agitate begins

6 Drain and Clutch Test

Selector position: Turn 5 clicks clockwise from the top.

Purpose of test: Drain system with the clutch mechanism

Activated components: Door lock, drain pump, clutch actuator

UI behaviour None

Working conditions: Door locked, drum stop, run clutch to spin mode and drain until empty +10

seconds more. Run clutch actuator for about 100 seconds

7 Drain and Spin Test

Selector position: Turn 6 clicks clockwise from the top.

Purpose of test: Verify drain system, and Pressure Sensor calibration procedure

Activated components: Door lock, main motor, drain pump.

UI behaviour None

Working conditions: Door locked, empty tub water level <5mm, if not the drain will run, if not in

spin mode the clutch actuator will run to spin position, spin up to maximum

speed.

8 Alarm History Test

Selector position: Turn 7 clicks clockwise from the top.

Purpose of test: Communicate alarm history
