NON-COIN 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 “S.A.F.E. System activated,” and the horn/tone will
sound until reset manually.
To reset the microprocessor once the control displays “S.A.F.E. System activated,” press the red
key on the
keyboard (touch pad).
NON-COIN S.A.F.E. SYSTEM CHECK PROCEDURE
The operation of the water solenoid valve can be tested to ensure that the water supply system and valve are
functional. Before attempting system check, be sure that ALL water supply shutoff valves to the dryer are in
the OPEN position, and the dryer must be in the “READY” mode where no cycle is loaded or in progress.
The procedure is as follows:
1. Press and hold the RED STOP key (while in “READY” mode and no cycle 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.
IMPORTANT: This is a test function only and the keys should be held and system activated for only
a second or so, otherwise water will accumulate in various places in the dryer.
COIN SYSTEM RESET
To reset the microprocessor once the control displays “S.A.F.E. System activated,” press and hold the “PAUSE”
key for 3-seconds.
S.A.F.E. DIAGNOSTIC MESSAGES
Open S.A.F.E. Probe Fault: This message indicates that the fire suppression probe is either not connected or
is damaged.
Shorted S.A.F.E. Probe Fault: This message indicates that the fire suppression probe is damaged or the
wiring is shorted.
Open S.A.F.E. Valve Fault: This indicates that the water valve coil is open, the resistance of the coil is too
high, or that it is not connected to the control.
Shorted S.A.F.E. Valve Fault: This indicates the water valve coil is shorted or the wiring to the valve is
shorted.
Water Not Connected: This indicates that there is no water pressure at the water valve. This will occur if
water is not connected to dryer or if there is low water pressure in the water line coming to the dryer. This could
also be a defective pressure switch or wiring to the pressure switch.
