Troubleshooting Guide
PROBLEM CAUSE CORRECTION
No soft water 1. No salt in the storage tank. Refill with salt and then use RECHARGE NOW feature.
No soft water & dis-
play is blank
1. Transformer unplugged at wall outlet, or
power cable disconnected from back of
electronic board or transformer malfunction.
Check for loss of power and correct. Reset electronic
controls and then use RECHARGE NOW feature.
2. Fuse blown, circuit breaker popped, or cir-
cuit switched off (See “Power Outage
Memory” on Page 14).
Replace fuse, reset circuit breaker, or switch circuit on,
and then use RECHARGE NOW feature.
3. Electronic control board malfunction. Replace electronic control board (See Page 23).
No soft water & salt
level not dropping
1. Salt storage tank “bridged”. Refer to “Breaking a Salt Bridge” section to break.
2. Bypass valve(s) in “bypass” position. Move bypass valve(s) to “service” position.
No soft water & salt
storage tank full of
water,
water running to
drain while unit is in
the soft water cycle
1. Dirty, plugged or damaged nozzle & venturi
assembly
Take apart, clean and inspect nozzle & venturi (See
“Cleaning the Nozzle & Venturi” section.
2. Inner valve fault causing leak. Replace seals and rotor.
3. Valve drain hose is plugged. Hose must not have any kinks, sharp bends or any water
flow blockage (See “Valve Drain Requirements” section.
4. Valve drain line and Salt Storage Tank
overflow drain connected together by a tee.
Disconnect tee and run separate drain lines.
5. Low or high system water pressure (low
pressure may disrupt brine draw during
recharge, high pressure may cause inner
valve parts failure).
If pressure is low, increase well pump output to a mini-
mum 20 psi. If daytime pressure is over 100 psi, add a
pressure reducing valve in the supply pipe to the soften-
er. Contact a licensed plumber.
6. Brine float dirty or broken. Clean or replace Brine Valve Float Assembly.*
7. Leak between valve and resin tank. Replace o-rings between resin tank and valve.
Water hard some-
times
1. Incorrect time set. Check and change time setting.
2. Incorrect water hardness set. Refer to “Set Water Hardness” section to set correctly.
3. Incorrect model code programmed. Refer to “Program the Water Softener” section to set cor-
rectly.
4. Hot water being used when softener is
regenerating.
Avoid using hot water while the softener is regenerating,
as the water heater will fill with hard water.
5. Possible increase in water hardness. Test untreated water for hardness and iron, and program
the water softener accordingly (See “Set Water
Hardness”) section to set.
6. Leaking faucet or toilet valve. Excessive
water usage.
A small leak can waste hundreds of gallons of water in a
few days. Fix all leaks and always fully close faucets.
Iron in water 1. Clear water iron in water supply. Test untreated water for hardness and iron, and program
the water softener accordingly (See “Set Water
Hardness”) section to set.
2. Iron in soft water. Clean resin bed with Resin Bed Cleaner. Follow instruc-
tions on package.
3. Bacterial or organic bound iron. Cannot be treated by water softener.
Resin in house hold
plumbing
1. Crack in distributor or riser tube. Replace resin tank assembly.
Salt storage tank
leaking
1. Crack in brine tank. Replace salt storage tank assembly.
Motor stalled or
clicking
1. Motor malfunction or internal valve fault
causing high torque on motor.
a. Replace rotor/seal.
b. Replace motor & switch.
Error code E1, E3 or
E4 appears
1. Fault in wiring harness or connections to
position switch.
Replace wiring harness or connections to position switch.
2. Fault in switch. Replace switch.
3. Fault in valve causing high torque. Replace rotor/seal.
4. Motor inoperative. Replace motor.
Error code E5 1. Electronic control malfunction. Replace electronic control board.
