TICE explanation: Water supply → ice making → ice dropping → reset

．
Exceptional operation
1) When the consumer input stops in off-ice and water supply
If the "off" and "ice" is just in operation when the ice-making mode is cancelled in "off"
and "ice" and water supply, stop is executed after it is end. Stop is executed immediately in water supply.
2 ) When the freezer door is open in "off" and "ice" and water supply
Stop the ice making running immediately, and execute the rest operation after the door is OFF.(The cycle
time of ice maker is closed)
3) Full ice is sensed by the ice probe rod
When full ice is normally sensed by the ice probe rod, the ice maker returned to the normal position. Water
supply is stopped before full ice is relieved.
※
"off" and "ice" attempt is done at an interval of 30 min.
3. Motion specification of water supply pump
Water shall be supplied for 5.5 seconds after normal "off" and "ice" ends and then the water valve motion
for water supply shall be stopped.
4. Specification of water supply pipe heating wire
1) When the ice maker is working, the ice-making cycle is Tice.
Working time of water supply pipe heater T
T=Tice×40%
2) When the ice maker stops working, the water supply pipe heating wire is OFF.
5. Operation of ice maker
1) When there is error of signal input error at the "off" and "ice" position and the ice maker position is
impossible to grasp, rotation is made in opposite to the rotation direction at that
time. It is abnormity if there are 3 errors of sensing position, and motion shall be stopped at this time. The
ice maker shall be initiated in 20 min after abnormity occurs, "off" and "ice" shall be
conducted continuously when the initiation is completed without any error.
2) When the ice maker cannot be reset normally, ice maker fault is indicated and the freezer temperature
display area in the locked state displays EO fault, which will disappear after 5 min.
3) Each time the freezer door is closed from open after the ice maker fault, the ice maker is re-initialized.
Meanwhile, the fault is removed when the ice maker returned to the normal position.
4) When the eye detection is entered, the ice maker is re-initialized by itself. Meanwhile, the fault is
removed when the ice maker returned to the normal position.
Entry conditions: refrigerator and freezing door open, meanwhile enter the ice and lock button can be four
beeps
Load action: ice machine action once after the water pump for continuous switching action (open 2s, off 2s)
Discharge conditions: refrigerator and freezing door closed
