Main Solenoid Valve (F
1
) Circuit
Check the main solenoid if error indicator “11” is displayed.
a.) Disconnect Main Solenoid connector and measure resistance between Pink and Black.
Normal:
37~43
If normal, proceed to b).
Faulty:
Replace Main Solenoid.
b.) Measure voltage between Pink-Black of Main Solenoid connector.
Normal:
DC11~13V
If normal, proceed to Solenoid Valve F
2
Faulty:
Replace PCB.
4b.Solenoid Valve 1 (F
2
) Circuit
Check Solenoid 1 if error indicator “11” is displayed.
a.) Disconnect Solenoid 1 connector and measure resistance between Red and Black.
Normal:
37 ~ 43
If normal, proceed to b).
Faulty:
Replace Solenoid 1.
b.) Measure voltage between Red and Black of Solenoid 1 connector.
Normal:
DC 11 ~ 13V
If normal, proceed to Solenoid Valve 2 (F
3
) Circuit
Faulty:
Replace PCB.
4c. Solenoid Valve 2 (F
3
) Circuit
a.) Disconnect Solenoid Valve 2 connector and measure resistance between Orange and
Black.
Normal:
37 ~ 43
