Coin – To reset the microprocessor once the control displays
"S.A.F.E. System Was Activated", press and hold the red
"Pause" key for 3-seconds on the keypad.
S.A.F.E. System 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.
Non-Coin
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
tumbler area as long as both keys are held.
The Phase 7 non-coin microprocessor controller (computer)
will prompt the user to perform a S.A.F.E. system 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 S.A.F.E. system 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.
Coin
While the control is in the program mode, press and hold the
"Pause" key for 3-seconds to get into the valve test mode.
Valve test mode: The control will display "Press and Hold
Medium to Open Water Valve". When the "Medium" key is
pressed, the control will activate the water output.
S.A.F.E. System Diagnostics
Non-Coin – In the event that the Phase 7 non-coin
microprocessor controller (computer) detects a fault in the
S.A.F.E. system, the control will display the message "S.A.F.E.
System Disabled...Ready". To find out why the S.A.F.E.
system 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 "S.A.F.E. System
Diagnostics Messages" section.
Coin – In the event that the Phase 7 microprocessor controller
(computer) detects a fault in the S.A.F.E. system, the control
will display the message "S.A.F.E. System Disabled...Ready,
Insert XX To Start". To find out the reason for the S.A.F.E.
system disabling, press and hold the red "Pause" and "Low"
keys. This will cause the control to display a diagnostic
message, as detailed in the following section.

S.A.F.E. System Diagnostics Messages
Open Thermistor Probe – This message indicates that the
S.A.F.E. system thermistor probe either is not connected or
is damaged. If this condition is detected, the Phase 7 non-
coin control will immediately enter S.A.F.E. System Disabled
mode.
Shorted Thermistor Probe – This message indicates that
the S.A.F.E. system thermistor probe is damaged or the wiring
is shorted. If this condition is detected, the Phase 7 non-
coin control will immediately enter S.A.F.E. System 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 S.A.F.E. System Disabled mode. Once the
condition is corrected, the control will continue to monitor the
condition for 1 minute before exiting S.A.F.E. System 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 S.A.F.E. System Disabled mode. Once the
condition is corrected, the control will continue to monitor the
condition for 1 minute before exiting S.A.F.E. System 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 S.A.F.E. System Disabled mode.
Once the condition is corrected, the control will continue to
monitor the condition for 1 minute before exiting S.A.F.E.
System Disabled mode.
Starting A Cycle When Computer Is In
"S.A.F.E. System Is Disabled" Mode
Non-Coin – When the S.A.F.E. system is disabled, the user
can still start a cycle. However, when a cycle is started, the
control will display the following message: "S.A.F.E. System
Is Disabled. Press 'Start' to Continue". This message will
be displayed every time a cycle is started, until the disabling
condition has been corrected.
Coin – When the S.A.F.E. system is disabled, the user can
still start a cycle. Simply insert credit and select a cycle to
start.
