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

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
