Unplug the water tank, power on the
oven, put oven into test mode 00.
Fill the tank with water to the water
level 2 and plug tank into oven.
Did water transfer from tank to Water
Level unit?
Are there disconnection and short circuit in the water level sensor
connectors, connecting between the board and the sensor section?
Are there disconnection and short circuit in the water level sensor
connectors, connecting between the board and the sensor section?
Measure resistance of a set of the three (3) water level sensors with the
sensor connecting connector pulled out of the board.
Measure resistance of a set of the three (3) water level
sensors with the sensor connecting connector pulled out of
the board. (with the water tank filled with water)
Is the measured resistance value of
the set infinite?
Is the measured resistance value
of the set infinite?
Replace the control board or
the display board.
Replace the control board or the display board.
Check/replace the connection between the tank and the
Water Level unit.
Do the H-side and L-side water level sensors
indicate 01 or more in the test mode?
Is ion-changed or pure water being used?
Use common tap water.
After confirming that the water level sensor wiring of
the water tank is OK, replace the Water Level unit.
After confirming that the water level sensor wiring of the water tank is OK,
replace the Water Level unit.
Is the oven in the following conditions?
Test mode: 00 (see [9] TEST MODE page 21,22)
H-side water level sensor: 00 h
L-side water level sensor: 00 h
Is the unit in the following conditions?
Test mode: 00 (see [9] TEST MODE page 21,22)
H-side water level sensor: 80 (h) or more
L-side water level sensor: 80 (h) or more
Repair connector.
Repair connector.
If there is water touching/ covering the
three water level sensors it is NOT infinite.
You get anywhere from a few M ohms to a
few hundreds of K ohms.
