Low flow reading on
reject/flush (Makeup
Flowmeter) / Low
Pressure Reading
●
System feed is off
Verify pressure to the
system
●
Flowmeter sensors
disconnected at board
Verify connection at board,
check reading on factory
interface
●
Flowmeter turbine is stuck
Verify sensor operation
(w/magnet), if it reads, then
the turbine is probably
stuck. Replace, re-verify
●
Reject Solenoid Valve is
damaged
Verify solenoid operation /
Replace
●
Membrane pack is
damaged (xleak)
Check xleak on module*
●
Pressure Sensor is
damaged / not connected
Check connection / verify
sensor reading
●
Flowmeter calibration is
off
Start with default values re-
calibrate flowmeters
through factory interface*
Continuous feed flow
during Idle Mode
● ● ● ● ●
blown fitting on system
Bypass system, repair leak
Failure reported by
conductivity circuit
OR sensor is reading
0uS or >1500uS
●
●
No Conductivity Read
Verify that the sensor is
plugged in, verify there is
water in the line, no air
bubbles
●
PCB failed to start
PCB boot issue…
●
>1500uS
Verify reading with external
tool, this can also happen
when the process is
stopped in the middle of a
cycle and the valves
switch, placing the
concentrate loop into the
dilute loop, which is greater
than 1500uS

Reset system, confirm
function
