PC board
C . Restricted/stalled meter turbine
D . Incorrect programming
E . Meter wire not installed securely into three
pin connector
F . Defective meter
G . Defective PC board
A . Bypass valve is open or faulty
B . Media is exhausted due to high water usage
C . Meter not registering
D . Water quality fluctuation
E . No regenerant or low level of regenerant in
regenerant tank
F . Control fails to draw in regenerant
G . Insufficient regenerant level in regenerant tank
H . Damaged seal/stack assembly
I . Control valve body type and piston type
mix matched
J . Fouled media bed
A . Improper refill setting

C . Check for leaking fixtures that may be
exhausting capacity or system is undersized
A . Check incoming water pressure – water
pressure must remain at minimum of 25 psi
B . Replace injector with correct size for
the application
C . Check drain line for restrictions or debris
and clean
A . Check refill setting
B . Remove injector and clean or replace
C . Retighten the drive cap assembly
