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.
NON-COIN
1. Press and hold the red “STOP/CLEAR” key (while in “READY” mode and no cycle is in progress).
2. Press and hold the “A” key.
3. 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.
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.
F.S.S. Diagnostics
NON-COIN – 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.
COIN – In the event that the Phase 7 microprocessor controller (computer) detects a fault in the F.S.S. system,
the control will display the message “F.S.S. DISABLED…READY, INSERT XX TO START”. To find out the
reason for the F.S.S. 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.
