b.) Measure the voltage of the connector on the PCB.
Normal: Between Brown and Grey AC 30~50V
Between Yellow and Grey AC 180~220V
If normal, proceed to
c.).
Faulty: Replace transformer.
c.)
Measure voltage between White and Black of connector (F) on PCB.
Normal: AC 90~110V
If normal, proceed to 4.
Faulty: Replace transformer.
Note) The above transformer voltages are measured while the appliance is in standby mode - not
while it is operating.
14. Bypass Servo Circuit 15.
a.)
Disconnect relay connector (G
1
) and measure resistance.
If normal, proceed to
b
.).
Faulty: Replace PCB.
b.)
Measure working voltage while relay connector (G
1
) is connected.
Faulty: Replace Bypass Servo.
15.Remote Control
Check the voltage between the 2-core remote control cable.
Measure the voltage between terminals on the remote control terminal (D
1
).
Normal: DC 11~13V
If normal, replace the remote control after confirming that the cable hasn’t been
damaged or shorted.
Faulty : Because normal voltage is not given due a short circuit, despite the PCB being in
normal state, check Water Flow Servo circuit.
If solution is not given from the above replace PCB.
