System Reset _________________________
After the microprocessor determines that the situation is under
control and shuts the water being injected into the basket
(tumbler) off, the microprocessor display will read “F.S.S. WAS
ACTIVATED”, and the horn/tone will sound until reset manually.
To reset the microprocessor once the control displays “F.S.S.
WAS ACTIVATED”, press the red “Stop/Clear” key on the
keyboard (touch pad).
F.S.S. Water Valve Check _____________
The operation of the water solenoid valve can be tested to
ensure that the water supply system and valve are functional.
Before attempting a system check, be sure that all water
supply shutoff valves to the dryer are in the Open position; the
dryer must be in the “READY” mode with no cycle loaded or in
progress.
• Press and hold the red “Stop/Clear” key (while in “READY”
mode and no cycle is in progress).
• Press and hold the “A” key.
• Water valve will open and water will be dispensed into
basket (tumbler) area as long as both keys are held.
The Phase 7 non-coin microprocessor controller (computer)
will prompt the user to perform a F.S.S. valve check at every
4000 hours to ensure proper functionality. At the 4000 hour
mark, the control will wait for end of the cycle and then will
prompt the user to “PLEASE EMPTY TUMBLER, THEN PRESS
THE ‘STOP/CLEAR’ AND ‘A’ KEYS TO TEST THE WATER
VALVE.” When the ‘STOP/CLEAR’ and ‘A’ keys are pressed,
the control will activate the F.S.S. water valve for 2 seconds, at
which point the control will prompt the user with the following
message: “IF WATER DID NOT TURN ON, CALL FOR
SERVICE. THANK YOU.”
Note
The control will not let the user continue until the valve
test has been completed.
F.S.S. Diagnostics _____________________
In the event that the Phase 7 non-coin microprocessor
controller (computer) detects a fault in the F.S.S. system, the
control will display the message “F.S.S. DISABLED…READY.”
To find out why the F.S.S. is disabling, press and hold the red
“Stop/Clear” and green “Start” keys. This will cause the control
to display a diagnostic message, as detailed in the “F.S.S.
Diagnostics Messages” section.
F.S.S. Diagnostics Messages __________
Open Thermistor Probe
This message indicates that the F.S.S. thermistor probe either
is not connected or is damaged. If this condition is detected,
the Phase 7 non-coin control will immediately enter F.S.S.
DISABLED mode.
Shorted Thermistor Probe
This message indicates that the F.S.S. thermistor probe is
damaged or the wiring is shorted. If this condition is detected,
the Phase 7 non-coin control will immediately enter F.S.S.
DISABLED mode.
Disconnected Water Valve
This message indicates that the water valve is open or that it
is not connected to the control. If this condition is detected,
the Phase 7 non-coin control will continue to monitor the
condition for a period of 5 minutes before entering F.S.S.
DISABLED mode. Once the condition is corrected, the control
will continue to monitor the condition for 1 minute before exiting
F.S.S. DISABLED mode.
Shorted Water Valve
This message indicates that the water valve is shorted or
that the wiring to the valve is shorted. If this condition is
detected, the Phase 7 non-coin control will continue to monitor
the condition for a period of 5 minutes before entering F.S.S.
DISABLED mode. Once the condition is corrected, the control
will continue to monitor the condition for 1 minute before exiting
F.S.S. DISABLED mode.
Water Not Connected
This indicates that there is no water pressure at the water
valve. This will occur if water is not connected to the dryer, or
if there is low water pressure in the water line coming to the
dryer. This could also signify a defective pressure switch or
defective wiring to the pressure switch. If this condition is
detected, the Phase 7 non-coin control will continue to monitor
the condition for a period of 5 minutes before entering F.S.S.
DISABLED mode. Once the condition is corrected, the control
will continue to monitor the condition for 1 minute before exiting
F.S.S. DISABLED mode.
Starting a Cycle When Computer is in
“F.S.S. is Disabled” Mode_______________
When the F.S.S. is disabled, the user can still start a cycle.
However, when a cycle is started, the control will display the
following message: “F.S.S. IS DISABLED. PRESS ‘START’
TO CONTINUE.” This message will be displayed every time
a cycle is started, until the disabling condition has been
corrected.
