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.
