Problem Possible Causes What To Do
Run out of soft water Incorrect injector • With water pressure > 70 psi, use 4 bump injectors
between regenerations (WS15X10059).
Improper regeneration • Repeat regeneration, making certain correct salt dosage is
used.
Fouled resin bed • Use resin cleaner.
Incorrect salt dose and capacity setting • Set Salt per Regen and Capacity setting to proper level. Refer to

disc open.
Valve disc 2 not closed during brine • Manually operate cam gear to flush out foreign matter holding
draw, causing brine refill disc open.
Air leak in brine line to air check • Check all connections in brine line for leaks.
Salt setting too high • Set in new values. Refer to Advanced Programming section.
Float assembly malfunctions • Inspect float assembly in brine well for proper operation.
