Message
Possible Causes
Action
Inlet Solenoid Err
No inlet water supply.
Check inlet water connection.
Ensure feed water is turned on.
Inlet solenoid not connected to
board or connected improperly.
Check connection.
Inlet solenoid not functioning.
Replace inlet solenoid
(RY1265X2).
Regulator not functioning properly.
Replace regulator (PM1403X1).
Pressure Sensor Er1
Pressure sensor not connected to
board, or improperly connected.
Check connection.
Pressure sensor not functioning.
Replace pressure sensor(s)
(TD1403X1) and recalibrate.
Check calibration tag
Ensure that reading on tag
agrees with reading in software.
Pressure Sensor Er2
Pressure sensor not connected to
board, or improperly connected.
Check connection.
Pressure sensor not functioning.
Replace pressure sensor(s)
(TD1403X1) and recalibrate.
Possible leak, prefilter installed
incorrectly or faulty prefilter.
Check for water spillage. If
none, check installation of pre-
filter or replace prefilter
(D502113) if necessary.
Prefilter and membrane pressure
sensors not connected to control
board or improperly connected.
Check connections.
Check calibration tag.
Ensure that reading on tag
agrees with reading in software.
Pressure Sensor Er3
Pressure sensor not connected to
board or improperly connected.
Check connection.
Pressure sensor not functioning.
Replace pressure sensor(s)
(TD1403X1) and recalibrate.
Possible leak, or MPS or carbon fil-
ter installed incorrectly or faulty.
Check for water spillage. If
none, check installation of MPS
(D502114) and carbon filter
(D502115)
Check calibration tag.
Ensure that reading on tag
agrees with reading in software.
