Troubleshooting Guide
SYMPTOM PROBABLE CAUSE CORRECTION
1.Softener Fails to
Regenerate
Automatically
Power supply plugged into
intermittent or dead power source
Connect to constant power source
Disconnected meter cable Reconnect cable
Improper control valve
programming
Reset program settings
Defective power supply Replace power supply
Meter is dirty or defective Clean or replace meter assembly
Defective Drive motor Replace motor
2. Regeneration at
Wrong Time
Time of day improperly set, due to
power failure
Reset time of day programming and
install 9-volt battery.
Regeneration time set improperly Reset regeneration time programming
3. Loss of Capacity
Increased raw water hardness Increase hardness setting or decrease
days between regeneration
Brine concentration and or / quantity Keep brine tank full of salt at all times.
Clean it yearly. Salt may be bridged.
If using a salt grid plate, ensure refill
water is over it.
Resin fouling Call dealer. Find out how to confirm
it. Clean the resin and prevent future
fouling.
Poor distribution, channeling (uneven
bed surface)
Call dealer. Check backwash flow.
Regenerate more frequently
Internal valve leak Call dealer. Replace spacers, seals
and / or piston
Resin age Call dealer. Check for resin oxidation
caused by chlorine. Mushy resin.
Resin loss Call dealer. Check for correct bed
depth. Broken distributor tube. Air or
gas in bed: well gas eliminator. Loose
brine line.
4. Poor Water
Quality
Check items listed in #1, #2, and #3
Bypass valve open Close bypass valve.
Channeling Check for too slow or high service
flow. Check for media fouling.
5. High Salt Usage
High salt setting Lower brine tank refill time
Excessive water in brine tank See symptom #7
Constant flow through the unit Indicates plumbing leak (e.g. toilet
tank)
Regenerating too frequently Lower hardness setting or increase
days between regeneration.
6. Loss of Water
Pressure
Scaling / fouling of inlet pipe Clean or replace pipline. Pretreat to
prevent.
Fouled resin Clean resin. Pretreat to prevent.
Improper backwash setting Backwash more frequently
