6. If the valve is silent, measure the continuity of its solenoid coil as shown below.
Measure the DC resistance
between pins 1 & 2.
It is approx. 12 to 15
Ω
.
7. If the resistance value is abnormal (shorted or open), then replace the Valve.
8.
If resistance value is OK, then measure the DC voltage at the connector, pins between 1 & 2.
This should be 12V.
9.
If the voltage is 0 on the step above, measure a DC voltage on the terminals marked as
“3WAY” on the Control Circuit board. If there is 12V present, then check the connecting
cable between the Valve and Circuit board.
10.
If no voltage indication on the terminals, check to see if the “3-WAY VALVE” LED is
illuminated on the board. If it is off, then replace the Control board.
Fresh Water Flush Adjustment
1. Disassemble the Controller Enclosure and open it by removing 4 screws.
2.
Press the “Start” switch, then the “Stop” switch.
3.
