3) The opening backup timer starts counting when the water pan starts to open. If the
hall IC does not turn on within 3 minutes, the display shows “EE” and the unit stops
for 60 minutes. If the error recurs after the unit resumes operation, the display shows
“EE” and the unit shuts down (recorded as “E3” in error history).
[c] DEFROST CYCLE
1) After the water pan opens, the hot gas valve opens until the defrost completion
temperature is reached.
2) If the defrost completion temperature is not reached even when the defrost backup
timer counts up (30 minutes after water pan starts to open), the display shows “E2”
and the unit stops.
If the hot gas valve fails to open, the unit may stop with the “E2” error.
* The defrost completion temperature is adjustable in the maintenance mode (see “3.
[b] MAINTENANCE MODE”).
[d] WATER PAN CLOSES
1) When the cube control thermistor senses the evaporator temperature above the
defrost completion temperature, the hot gas valve closes, the fan motor starts, and
the water pan starts to close.
2) The closing backup timer starts counting when the water pan starts to close. If the
hall IC does not turn on within 3 minutes, the display shows “EE” and the unit stops
for 60 minutes. If the error recurs after the unit resumes operation, the display shows
“EE” and the unit shuts down (recorded as “E4” in error history).
* In the initial cycle or when the water temperature is below 13°C, the water valve
opens to supply defrosting water for 10 seconds after the water pan starts to close.
