Troubleshooting
Your water conditioning system is designed and
manufactured for efficient, low maintenance service.
However, if problems do occur, this section provides
a list of possible causes and solutions
Alarms
The control continuously monitors itself and sounds
an alarm if it detects something wrong. The alarm is a
beep that is on for one second and then off for nine
seconds. When the alarm sounds, the display shows
the letter Err with a number from 1 to 4. Table 2 lists
Err numbers, and solutions. To silence the alarm,
press any button on the control. If the error still exists,
the control will go back to the alarm condition after 30
seconds.
Refer to table 3 to help identify the cause of a prob-
lem. You can solve some problems yourself, such as
low salt in the storage tank or a blown household
fuse. However, some problems require installer or
dealer assistance.
