Power failure
Softener delivers By-pass valve is open
hard water
No salt is in brine tank
Injector screen plugged
Insufficient water flowing into brine tank
Hot water tank hardness
Leak at distributor tube
Internal valve leak
Reserve capacity has been exceeded
Meter is not measuring flow
Unit used too Improper salt setting
much salt
Excessive water in brine tank
Loss of water Iron buildup in line to water conditioner
pressure
Iron buildup in water conditioner
Inlet of control plugged due to foreign
material broken loose from pipes by
recent work done on plumbing system
Loss of mineral Air in water system
through drain line
Improperly sized drain line flow control
Iron in conditioned Fouled mineral bed
water
Excessive water in Plugged drain line flow control

Foreign material in brine valve
Foreign material in brine line flow control
Softener fails to Drain line flow control is plugged
draw brine
Injector is plugged
Injector screen plugged
Line pressure is too low
Internal control leak
Service adapter did not cycle
Control cycles Misadjusted, broken, or shorted switch
continuously
Resin and gravel Damaged lower distributor screen

Correction
Assure permanent electrical service (check circuit breaker, GFCI,
fuse, plug, pull chain, or switch)
Replace controller
Reset time of day
Close by-pass valve
Add salt to brine tank and maintain salt level above water level
Clean injector screen
Check brine tank fill time and clean brine line flow control if plugged
Repeated flushings of the hot water tank is required
Make sure distributor tube is not cracked. Check O-ring and
tube pilot
Replace seals and spacers and/or piston
Check salt dosage requirements and adjust program to provide
additional reserve
Clean meter of foreign debris. Replace meter dome
Check salt usage and salt setting
See- Problem "Excessive water in brine tank"
Clean line to water conditioner
Clean control and add mineral cleaner to mineral bed. Increase
frequency of regeneration
Remove piston and clean control valve
Assure that well system has proper air eliminator control. Check
for dry well condition
Check for proper drain rate
Check backwash, brine draw, and brine tank fill.
Increase frequency of regeneration. Increase backwash time.
Clean flow control
Clean injector and screen
Replace controller
Replace brine valve seat and clean valve
Clean brine line flow control
Clean drain line flow control
Clean injector
Clean screen
Increase line pressure to 20psi
Change seals, spacers, and piston assembly
Check drive motor and switches
Determine if switch or controller is faulty and replace it, or
replace complete power head
Replace distributor screen
Replace resin
