Brine System Analysis
1) WATER LEVEL in the brine tank
a) Empty
b) Below level of safety valve
c) At level of safety valve float
If the brine system is functioning properly, there will be water in the brine tank, but the level should be below the safety valve
float and the fiberglass rod should travel freely. If these conditions do not exist, one of the following conditions will indicate the
nature of the problem:
1. NO WATER IN BRINE TANK – ROD TRAVELS FREELY. The flow control is plugged. Remove refill flow control. Clean or
replace.
2. NO WATER IN BRINE TANK – ROD IS RIGID. Air or water slammed the safety valve closed before water could enter the
tank. Clean parts at the base of the brine safety valve and also make sure that the seat of the check valve in the brine line
is clean. Check for possible air leaks in the brining system.
3. WATER IN BRINE TANK UP TO SAFETY VALVE FLOAT – ROD IS RIGID. There are three possible causes:
a. Brine piston is not in service position when control is in service or brine piston seals are defective. Remove brine line
while in service. There should be no flow to brine tank.
b. Refill flow rate is too high or refill time length is too long. Check refill flow rate and compare to specification in Appendix
A, Table 3 - Flow Rates.
Aqua-Sensor Troubleshooting
®
The following procedure will help you diagnose problems in units equipped with Aqua-Sensor® sensing device. Because many
"sensor problems" are actually regeneration problems, it contains a combination of sensor diagnostics and routine control valve
and brine system checks. Refer to the Troubleshooting Flow chart on page 50 for the recommended sequence and Appendix B
for suggested Aqua-Sensor® application guidelines.
Circuit Board Test
1. Verify there is 2.5 VAC power supply at the Culligan Gold Series™ circuit board for the Aqua-Sensor®.
2. Record program, DIP switch settings and statistical information (last slow rinse, Z ratio, Z minute and Z increase %) before
beginning this procedure.
3. Unplug the unit.
4. Remove the Aqua-Sensor® cable from the board.
5. Move DIP switch(es) to Test Mode. DIP switch 1 ON, all others OFF
6. Connect Soft-Minder® Meter/Aqua-Sensor® Tester (same as the Aqua-Sensor®, P/N 01017705) to board. The color of the
wire on the far right as you look at the back of the board should be white.
7. Move toggle to Balanced position.
8. Apply power; all segments should be lit on display.
9. Press any key. The software version should be displayed.
10. Press any key. Display should go blank except for solid "regen" icon and "OK" indicator. The "Regen" icon should stop
flashing within 30 seconds. The "OK" indicator means the control has sucessfully self-tested the Aqua-Sensor circuitry. If
"OK" does not appear, then replace the circuit borard.
11. Toggle to unbalanced position. Regen icon should flash.
12. If regeneration icon does not flash when balanced and flashes when unbalanced, then the board is good.
2) SAFETY VALVE in brine tank
a) Fiberglass rod travels up and down freely (approximately 1/2")
b) Fiberglass rod is rigid
