- Press the Start key 5 times: "HA" is displayed
=> Weight Detection (This should be performed right after the motor stops and the pulse value and
the water level are displayed)
- Press the Start key 6 times: END (Auto power S/W operation) => The Auto Power S/Wshould initiate
within 2 seconds (for mechanical switches).
※ Error detection should initiate within 3 seconds of all operations mentioned above.
(Water Level, Door/UNB, Hall-Sensor, Other Sensors)
《 Operation A 》
When a key is
entered, the
mechanical part
operates separately
=> When the water supply cycle is being performed, the Ag+ test should be available.
The "ㅂE'" error occurs when any kind of disconnection between the KIT PCB and the
terminal occurs, or in the overcurrent.
Check the KIT PCB and terminal for any disconnections before proceeding with the water
supply. If the silver kit is operating normally, "All Display" blinks for 10 seconds. (However, the
over- and low current sensors should all be set to HIGH)
(3) PCB Test Mode
a. Initial Access Mode: This is accessed by turning on the water level, reservation and power keys
at the same time and "All" is displayed.
b. After Initial Access Mode starts, the EEPROM is checked
c. EEPROM I/O Test
- Any EEPROM I/O error will display a blinking "Et" and an alarm beep. When no error is
detected, "Eg" appears.
※ When an EEPROM error occurs, only the power key can deactivate the test mode (no other
keystrokes are allowed).
d. Mode Switch: Use the Silver Nano key ( 01 → 02 → 03)
e. Displaying and controlling in Initial Access Mode
Pulsator
Selection Key
Mechanical Part

⑨ Water Supply
Hot water => Off
Each keystroke should perform the corresponding operation.
⑧ Water Level

⑦ Manual
Drainage Motor (On/Off)
The operations above should be initiated for the corresponding modes; while the
motor is running (Washing, Hydrating), the ⑧ key should not be activated.
