PROBLEM
No soft water
Water hard sometimes
Motor stalled or clicking
Error code Err01, Err02,
Err03 or Err04 displayed.
Error code Err05 dis-
played.
TROUBLESHOOTING - INITIAL CHECKS
Always make these initial checks first:
1. Is display blank? Check power source.
2. Is Error code displayed? If so, go to "Automatic
Electronic Diagnostics."
3. Is correct time displayed? If not, recharges occur at
the wrong time. Set present time.
4. Is there salt in the brine tank? If not, refill.
5. Is salt "bridged"?
6. Are plumbing bypass valve(s) in service position?
7. Are inlet and outlet pipes connected to the True Blue
water softener inlet and outlet respectively?
Troubleshooting Guide
CAUSE
No salt in the storage tank.
Salt is "bridged" (a layer of salt in the
salt storage tank has hardened).
If display is blank, power supply may be
unplugged at wall outlet, power cable
leads may be disconnected from the
electronic control board, fuse may be
blown, circuit breaker may be popped,
or power supply may be plugged into a
switched outlet which is "off."
Manual bypass valve(s) in bypass
position.
Dirty, plugged or damaged nozzle &
venturi.
Valve drain hose plugged or restricted.
Bypassed hard water being used dur-
ing recharge, due to present time or
recharge time settings being incorrect.
Hardness number setting is too low.
Hot water being used when softener is
recharging.
Increase in actual hardness of water
supply.
Turbine is not turning freely.
Motor malfunction or internal valve
fault causing high torque on motor.
Fault in wiring harness, connections to
position switch, switch, valve or motor.
Electronic timer (PWA) malfunction.
Add salt and then initiate a "Recharge Now".
Break salt bridge, as described on the previous
page, and then initiate a "Recharge Now".
Check for power loss due to any of these and
correct. When power is restored, if the display
shows the "Present Time" setting screen, it
means time was lost during the outage. Set the
present time. Other settings such as hardness
are retained in memory during a power loss.
Place bypass valve(s) in service position.
Take apart, clean and inspect the nozzle & ven-
turi assembly.
Drain hose must not have any kinks, sharp
bends, or be raised too high above the softener.
Check the time displayed. If not correct, refer
to "Set Present Time of Day". Check the regen-
eration starting time.
Referring to "Set Water Hardness Number",
check the current hardness setting and increase
if needed.
Avoid using hot water during recharges,
because water heater refills with hard water.
Have unsoftened water sample tested. Check
the current "Hardness" setting and increase if
needed.
Check turbine, as described on the next page.
Contact your dealer for service.

Contact your dealer for service.
8. Is valve drain hose free of kinks and sharp bends,
and not elevated over 8 feet above the floor.
9. Is the brine tube connected?
10. Check the hardness setting (See "Set Water
Hardness Number"). Be sure it is correct for the
household's water supply. Perform a hardness test
on a raw water sample to compare with the setting.
11. Perform a hardness test on a conditioned water
sample to determine whether a problem exists.
If no problem is found after making the initial checks,
proceed to "Troubleshooting - Manual Diagnostics" and
"Manual Advance Recharge Check" on the next two
pages.
