48 Maytag Co. 113395-6
Once the fire suppression system routine is activated, the microprocessor controller (computer) will display
“S.A.F.E. SYSTEM ACTIVATED” and water
will be injected into the basket (tumbler) chamber. Any time
water is being injected into the basket (tumbler), the basket (tumbler) drive will turn the load for 1-second every
15-seconds. This process will continue for a minimum of 2 minutes. After the 2 minutes have elapsed, the
microprocessor controller (computer) will check if the temperature remained above trip point; if so, the water
will remain on. The microprocessor controller (computer) will continue to check if the temperature is above trip
point every 30-seconds. If the water has been on for a constant 10 minutes, the water will be turned off,
regardless of the temperature, and the microprocessor controller (computer) will display “S.A.F.E. SYSTEM
WAS ACTIVATED”. If the temperature has dropped below trip point, the microprocessor controller (computer)
will turn off the water prior to 10 minutes.
SYSTEM RESET
After the microprocessor controller (computer) determines that the situation is under control and shuts the water
being injected into the basket (tumbler) off, the microprocessor controller (computer) display will read, “S.A.F.E.
SYSTEM WAS ACTIVATED”, and the horn/tone will sound until reset manually.
To reset the microprocessor controller (computer) once the microprocessor controller (computer) displays,
“S.A.F.E. SYSTEM WAS ACTIVATED”, press the red “STOP/CLEAR” key on the keypad.
FIRE SUPPRESSION 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.
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 microprocessor controller (computer) will prompt the user to perform a fire suppression system valve check
at every 4000 hours to ensure proper functionality. At the 4000 hour mark, the microprocessor controller
(computer) 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 microprocessor controller (computer) will activate the fire suppression
system water valve for 2-seconds, at which point the microprocessor controller (computer) will prompt the user
with the following message, “IF WATER DID NOT TURN ON, CALL FOR SERVICE. THANK YOU.”
NOTE: The microprocessor controller (computer) will not let the user continue until the valve test has
been completed.
FIRE SUPPRESSION SYSTEM DIAGNOSTICS
In the event that the non-coin microprocessor controller (computer) detects a fault in the fire suppression
system, the non-coin microprocessor controller (computer) will display the message, “S.A.F.E. SYSTEM
DISABLED…READY”. To find out why the fire suppression system is disabling, press and hold the red
“STOP/CLEAR” and green “START” keys. This will cause the microprocessor controller (computer) to display
a diagnostic message, as detailed in the “Fire Suppression System Diagnostics Messages” section.
