Troubleshooting
Your water conditioning system is designed and
manufactured for efficient, low maintenance service.
However, if problems occur, this section provides a list
of possible causes and solutions. You can solve some
problems yourself, such as low salt in the salt storage
tank or a blown household fuse. However, some
problems require installer or dealer assistance. Important: Service procedures that require the water
pressure to be removed from the system are marked
with a !. To remove water pressure from the system, put
the bypass valve or three-valve bypass into the bypass
position and open the backwash drain valve (the sixth
valve back from the control) with a screwdriver. Restore
system water pressure when the service work is
complete.
Problem Possible Cause Solution
