Message
Possible Causes
Action
Low Memb Pressure
MPS (D502114) or carbon cartridge
(D502115) is plugged.
Move cartridge to first position
and check pressure.. Replace
cartridge and reset timer.
Membrane failure or incorrect
installation.
Check membrane connections;
replace membrane(s) (FL1265X1)
if necessary.
Membrane pressure transducer out
of calibration.
Recalibrate membrane pressure
transducer.
RO pump failure.
Replace RO pump (PU1190X1).
Reject solenoid out of calibration or
stuck open.
Perform manual flush. If error
persists, replace solenoid
(RY1265X1).
Check UV interlock
(Reservoir UV)
Reservoir UV cover not in place.
Recheck UV cover position.
UV interlock actuator or sensor out
of position.
Check that the actuator is
attached to the cover and the
sensor is mounted to reservoir.
UV interlock cable not connected.
Check cable connections at the
reservoir circuit board.
UV interlock sensor not functioning.
Replace interlock sensor
(SW1406X1 for 30L, or
SW1407X1for 60L).
Check Res UV
Reservoir UV lamp cable not
plugged in.
Plug reservoir UV lamp cable
into control board.
Reservoir UV lamp burnt out or
inadequate UV output.
Replace reservoir UV lamp
(LMX31) and reset timer.
Reservoir UV lamp not properly
connected to UV cable connector.
Check connection to UV cover
and inside UV cover.
Check Res Ballast
Reservoir UV ballast out of
tolerance.
Replace ballast (TN1406X1).
Call Technical Services.
Check System UV
(TII UV)
System UV lamp cable not plugged
into control board.
Plug system UV lamp cable into
control board.
System UV lamp burnt out or
inadequate UV output.
Replace system UV lamp
(LMX13), and reset timer.
Chamber seal is compromised and
system UV lamp is getting wet.
Replace quartz sleeve and
o-rings (TU733X1 and GSX62)
System UV lamp not properly con-
nected to UV cable connector.
Check connection at UV
chamber.
