2. Disconnect the plug from J2 on the Main Control Board and
check for continuity between the pins in the plug. Open, check
the door strike. If good, replace the door switch assembly.
Closed replace the Main Control Board.
Swap hot and cold hoses.
Unplug machine for a few seconds then re-connect power.
Select a wash cycle and start cycle. If F01 reappears, replace
the Main Control Board as there is likely an internal problem
in the board. If the cycle performs without displaying F01, the
fault was temporary, no repair is required at this time.
The problem could be in the temperature sensor or the inlet
hoses may be reversed. In either case, the control will try to
resolve the error and the washer will continue to run. Before
testing the sensor, fi rst check the wiring to make sure it is
properly connected. To test the temperature sensor, unplug
the washer and disconnect wiring to the sensor. Use an
ohmmeter to measure the resistance of the sensor. A reading
below about 3K ohm or above about 163K indicates the sensor
may be bad and should be replaced.
This type of fault could be temporary or permanent. If this
fault occurs, the control will stop the washer and display F03.
For the fi ll system, the problem could be the inlet water is
turned off. To test the fi lling fault, run the washer with no load
and check if the tub fi lls to the proper level. If the tub over
fi lls or the water does not shut off, check the pressure switch
wiring and the pressure tube connection to the air dome and
pressure switch. If these check out, the problem could be in
the pressure switch or water valve. If the tub fi lls correctly,
run the washer in the Drain/Spin cycle to assure the pump
operates and pumps out water. If the pump is not running,
check the wiring connections. If the wiring is proper and
seated, measure the voltage across pins 1 and 2 on the pump
connector, it should be about 120VAC. If it is not, check the
voltage between pin 3 of the 4-pin connector (JX) and pin 3 of
the 8-pin connector (J11)(NEUTRAL). Voltage should measure
about 120VAC.

To test this fault, select and start the Heavy Duty cycle with
the heavy soil/stain option deactivated. The tub should be
rotating and begin fi lling with water. If the tub is not turning,
but is fi lling with water, wait about 30 seconds after the tub
is full and confi rm the washer is agitating. If the motor is
running and the tub fi lled, let the washer run for at least 6
minutes while measuring the voltage between pin 1 of the
8-pin connector(J11) and pin 7 of the 7-pin connector(J6). The
voltage should be below 50VAC when the timer advance is off
and should measure at line voltage when the timer advance
is on. Constantly monitor the volt meter throughout this 6
minute run time to be certain to observe the voltage change
as “timer advance on” is only on for a short time and could be
missed when it reverts to the lower voltage reading when timer
advance is off.

Frigidaire Diagnostic Mode
* Better models have a digital readout display.
* Good models do not have a digital readout display.
The diagnostic test is performed by using the program knob. To start the test:
* On non-digital display models, turn the program knob to the start position, Drain/Spin.
* On digital display models, turn the program knob to the start position, Touch Up.
* Press Pause/Cancel to turn off LED’s.
* Within 5 seconds, press and hold the Option and Pause/Cancel buttons until LED’s start sequentially chasing, then
release buttons.
1. All the LED’s will sequentially light. Pressing a button below a light cluster will light all the LED’s in that cluster at one
time to confirm functionality.
2. Turn the program knob (1) click clockwise from the start position. The hot water solenoid will activate and hot water
should enter through the detergent compartment.
3. Turn the program knob (2) clicks from the start position. The bleach water solenoid will activate and cold water
should enter through the bleach compartment.
4. Turn the program knob (3) clicks from the start position. The bleach and the wash water solenoids will activate and
cold water should enter through the softener compartment.
5. Turn the program knob (4) clicks from the start position. The door lock solenoid will activate.
6. Turn the program knob (5) clicks from the start position. The door lock solenoid will deactivate and the loading door
can be opened.
7. Turn the program knob (6) clicks from the start position. The washer will fill and tumble.
8. Turn the program knob (7) clicks from the start position. The washer will fill and spin (leakage test).
9. Turn the program knob (8) clicks from the start position. The drain pump and door lock solenoid will activate and the
washer will operate in high spin. Safety warning: if power is removed during this test, the door can be opened. To
prevent injury, do not put your hands inside when the tub is rotating.
10. Turn the program knob (9) clicks from the start position. The control will signal the last error code.
Quick Check
If there is no error displayed and the washer momentarily starts then turns back off:
1. Listen for a relay closure inside the Speed Control Board shortly after the Start key is pressed. If this happens, the
motor control has power.
2. Check the 5-pin connector wiring between the Console Control and the Speed Control Board.
If the model has a timer dial that can be Rotated 360°, turn the program knob to the start position, Drain/Spin.
NOTE
Section 2 Washing Machines
2-12
Frigidaire Diagnostic Mode (continued)
In the Better models line, the failure codes will appear in the display as an E followed by two numbers, a number and
a letter, or two letters. The control will beep and the door lock, wash, rinse, final spin and control indicator lights will
flash.
Example: E14. To stop the flashing, the customer may touch the Pause/Cancel button. The error code
remains stored in the control but once the problem is corrected, it does not effect the operation of the washer. If the
failure is something that the customer can correct (such as the water faucets being turned off), the washer will operate
normally the next time it is started.
In the Good models line, the control signals the failure code by flashing the five indicator lights of door lock, wash,
rinse, final spin and control for the first number or letter after the E and the start indicator light for the second number
or letter after the E. When a failure occurs, the washer stops or pauses and the control beeps and flashes the five
indicator lights to tell the customer that a failure has occurred. To stop the flashing and beeping, the customer may
touch the Pause/Cancel button. The error code remains stored in the control but once the problem is corrected, it does
not effect the operation of the washer. If the failure is something that the customer can correct (such as the water
faucets being turned off), the washer will operate normally the next time it is started.
To Recall an Error Code
* Wake the washer by pressing any button.
* Wait 5 seconds.
* Press and hold the Start and Pause/Cancel buttons simultaneously.
* All LED’s will go blank and after a few seconds the control will signal the stored code using audible beeps and blinking
LED’s. The control will repeatedly signal the code, as long as the Start and Pause/Cancel buttons are pressed. A two
second pause between repeats affords you the ability to make accurate counts to identify the correct error codes.
Example code F1: the first digit would be 15 and the second would be 1. If this code would appear on a washer in the
Good model line, the five indicator lights would blink fifteen times and the Start indicator light would blink once.
Troubleshoot problem by using charts on the following pages.
On a small number of washers with serial number prefix XC4, if the previous procedure does not preform as
specified, follow the option below:
* Follow all previous steps but instead of pressing Start and Pause/Cancel buttons, press and hold Options and
Pause/Cancel buttons.
* The control will pause for 2 seconds, then repeat the code as long as the two buttons are pressed and held.
A letter appearing in the code stands for a number higher than nine: A=10 B=11 C=12 D=13 E=14 F=15

Exiting Diagnostic Mode
There are two options for exiting the diagnostic test mode and returning the washer to normal operation:
a) Unplug the power cord, wait 5-8 seconds, then reconnect the power cord, or
b) Turn the program knob clockwise 2 or 3 clicks after the start position. Press Options and Pause/Cancel buttons
simultaneously for a few seconds until wash cycle LED’s appear.
If a situation arises where you cannot exit the diagnostic mode as described above and the bank of 5 LED’s on the
right end remain on regardless of program knob position, a combination of pushed buttons may have caused the
control to enter a special factory test mode. Disconnect power to reset the control to return washer to normal
operation if this occurs.
To Clear The Last Stored Error Codes
Place the control into diagnostic mode.
* Turn the program knob clockwise 9 clicks from the start position. The control will signal the last error code.
* Press and hold the Options and Pause/Cancel buttons for 3 seconds. The code will be cleared.
* Exit diagnostic mode to return the washer to normal operations.
