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.
