SECTION 6: SYSTEM TROUBLESHOOTING GUIDE
Problem Possible Cause Solution
1. Hard water (unit not using salt; liquid level in
brine tank NOT too high)
A. Electrical service to unit interrupted A. Assure permanent electrical service is working properly (check
fuse, plug, pull chain, or switch)
B. Timer not working. B. Replace timer assembly.
C. Timer improperly set C. Check programming function
D. Safety brine valve not opening D. Replace safety brine valve
E. Salt “bridged” in brine tank E. Breakup salt
F. Meter not functioning F. Clean or replace as necessary
2. Hard water (unit using salt; liquid level in
brine tank NOT too high)
A. Bypass open A. Close bypass (replace if necessary)
B. Timer improperly set B. Increase frequency of regeneration
C. No salt in brine tank C. Add salt; maintain above water level
D. Excessive water usage D. Increase frequency of regeneration and/or salt setting (See HOW TO
SET TIME OF DAY)
E. Unit installed backwards E. Reinstall unit
F. Unit undersized F. Replace with larger unit
3. Liquid level in brine tank TOO high
A. Brine valve not closing A. Replace brine valve
B. Salt setting too high B. Reset timer
C. Injector or Injector screen plugged C. Clean injector and screen
D. Drain line frozen, plugged or restricted D. Free drain
E. Salt “mushed” or sand from salt plugging bottom of
brine tank
E. Clean out brine tank (see instructions on page 4-1)
F. Incorrect brine line fl ow control (BLFC) F. Replace with correct fl ow control valve (see component part list on
page 9-1)
4. System regenerates at wrong time
of day
A. Timer improperly set A. Reset timer
5. Water continuously fl ows to drain
A. Foreign material in control valve A. Remove piston assembly and inspect bore: remove foreign material
and check control in various regeneration positions
B. Internal control leak B. Replace seals and/or piston assembly
C. Control valve jammed in brine or backwash position C. Replace piston, seals and spacers
6. Water tastes salty
A. Salt setting too high A. Reset program cycle
B. Distributor tube too short B. Replace
7. White spots on glassware and dark surfaces
A. Sodium residual resulting from water having very high
hardness or total dissolved solids (TDS)
A. Installation of additional water treatment equipment such as
reverse osmosis or demineralization
8. Low water pressure (low fl ow rate)
A. Iron build-up in line to water softener A. Clean line to water softener
B. Iron build-up in water softener B. Clean control and add Iron Reduction Media to resin bed: increase
frequency of regeneration
C. Well pumping sand C. Install sand trap
D. Pump losing capacity D. Contact pump repair service
9. “Rotten egg” smell (from hot water only) A. Magnesium rod in water heater A. Replace with aluminum rod or remove
10. “Rotten egg” smell (from both hot and cold
water
A. Hydrogen sulfi de (“sulfur”) in water supply A. Install CSX Sulfur Reduction System
B. Bacterial iron in water supply B. Install APIF or APPM Iron Reduction System
C. Algae in water supply C. Pour approximately 1/2 cup unscented laundry bleach into brine
well just before regeneration as frequently as necessary
11. Loss of resin through drain
A. Air in water system A. Assure that well system has proper air eliminator control: check for
dry well condition
