Troubleshooting Guide
Table 14 Troubleshooting Guide
System Display Fault Cause
(most likely to least)
Remedial Action
Very High Oxidant
Temp
Cell outlet
temperature exceeds
150° F
1. Low flow
through cell
2. Water solenoid
fuse failure
3. Oxidant
temperature
thermowell
fuse failure
1. Verify the
water flow is
within system
specs
2. Check fuse F10
on control
interface board
(Figure 34)
3. Check fuse F17
on control
interface board
(Figure 34)
High Brine Pump
Voltage
Brine proportion pump
control voltage
exceeds maximum
value for more than 60
seconds
1. Loss of brine
2. Brine solenoid
fuse failure
3. Brine
proportion
pump fuse
failure
4. Brine solenoid
failure
5. Cell fouled with
mineral
deposits
6. Worn out cell
1. Verify brine
supply to
system
2. Check fuse F9
on the control
interface board
(Figure 34)
3. Check fuse F6
on control
interface board
(Figure34)
4. Replace brine
solenoid
5. Verify water
softener is
functioning
correctly. Verify
salt meets
requirements
outlined in
Appendix B
6. Replace cell
Low Brine Pump
Voltage
Brine proportion pump
control voltage below
minimum value for
more than 60 sec.
1. Brine propotion
pump fuse
failure
2. Excessive brine
boost pressure
3. High Total
Dissolved
Solids (TDS) in
water
1. Check fuse F6
on the control
interface board
(Figure 34)
2. Adjust brine
boost pressure
to between 3-5
PSI
3. Verify feed
water meets
system
specifications
