Problem Possible Cause Solution
10. Residual regenerant being
delivered to service
a. Low water pressure
b. Plugged, fouled, or incorrect
injector size
c. Restricted drain line
d. Damaged seal/ stack assembly or
piston allowing leakage during
draw
e. Draw time too short
f. Excessive re
fi ll
g. Vacuum leak in draw line / elbow
a. Check incoming water pressure – water
pressure must remain at minimum of
25 psi
b. Inspect and clean or replace injector,
or replace injector with correct size for
the application
c. Check drain line for restrictions or
debris and clean
d. Check seal/ stack assembly and piston
for damage and replace
e. Program proper draw time needed
f. Program proper re
fi ll time needed
g. Locate vacuum leak and fi x
11. Excessive water in
regenerant tank
1) Tank is being over fi lled
a) Improper program settings
b) Missing re
fi ll fl ow controller
2) Previous regenerant is not being
drawn out
1) Excess from fi ll cycle
a) Verify program settings
b) Visual inspection / measure
volume output into container
2) See Troubleshooting Guide #12
12. Control valve fails to draw in
regenerant
a. Injector is plugged
b. Faulty regenerant piston
c. Regenerant line connection leak
d. Drain line restriction or debris cause
excess back pressure
e. Drain line too long or too high
f. Low water pressure
g. Damaged seal/ stack assembly
a. Remove injector and clean or replace
b. Replace regenerant piston
c. Inspect regenerant line for air leak
d. Inspect drain line and clean to correct
restriction
e. Shorten length and/or height
f. Check incoming water pressure – water
pressure must remain at minimum of
25 psi
g. Inspect seal stack assembly for damage
and replace
13. Water running to drain
a. Power outage during regenera tion
or unit is currently in regeneration
b. Damaged seal/ stack assembly
c. Piston assembly failure
d. Drive cap assembly not tightened
properly
a. Upon power being restored control will
fi nish the remaining regeneration time.
Reset time of day.
b. Replace seal/ stack assembly
c. Replace piston assembly
d. Re-tighten the drive cap assembly
14. Motor drives intermittently
during regeneration.
a. Low power a. See Table 2 Software and Power Supply
