3a.Main Solenoid Valve (SV
0
) Circuit.
Check the main solenoid if error indicator
“11” is displayed.
a.)
Disconnect Main Solenoid connector and
measure resistance between Pink and
Black.
Normal:
1.5~1.9k
Ω
If normal, proceed to
b
.
Faulty:
Replace Main Solenoid.
b.)
Measure voltage between Pink-Black of
Main Solenoid connector.
Normal:
DC80~100V
If normal, proceed to Solenoid Valve
SV
1
Faulty:
Replace PCB.
3b.Solenoid Valve 1 (SV
1
) Circuit.
Check Solenoid 1 if error indicator “11” is
displayed.
a.)
Disconnect Solenoid 1 connector and
measure resistance between Red and
Black.
Normal:
1.8~2.2k
Ω
If normal, proceed to
b
.
Faulty:
Replace Solenoid 1.
b.)
Measure voltage between Red and Black
of Solenoid 1 connector.
Normal:
DC80~100V
If normal, proceed to Solenoid Valve 2
(SV
2
) Circuit
Faulty:
Replace PCB.
3c. Solenoid Valve 2 (SV
2
) Circuit.
a.)
Disconnect Solenoid Valve 2 connector
and measure resistance between Orange
and Black.
Normal:
1.8~2.2k
Ω
If normal,, proceed to
b
.
Faulty:
Replace Solenoid Valve 2.
b.)
Measure voltage between Orange and
Black of Solenoid Valve connector.
Normal:
DC80~100V
If normal, proceed to Thermal fuse Cir-
cuit.
Faulty:
Replace PCB.
