Description Cause
 Motor stall
Rotor blocked
 Loss of rotor synchronism or
rotor blocked by external
materials
EEPROM Data EEPROM Data memory corrupted
memory error
Grid voltage error Voltage supply out of operating
range
Motor winding Motor thermal protection trip
temperature error
Power module Frequency converter thermal
temperature error protection trip
Generic hardware Hardware error
error
Dry-run error Dry run detection
LOW error Lack of water detection (if P48=
ERR)
Pressure sensor Missing pressure sensor (not
error present in ACT mode)
Low pressure error Pressure below minimum
threshold (not present in ACT
mode)
Loss of phase error One of the three power supply
phases is missing (three-phase
versions only)
Pressure sensor No pressure sensor 1 detected
error 1
Pressure sensor No pressure sensor 2 detected
error 2
Remedy
 Check that there are no foreign bodies
preventing the pump from turning
 Stop the pump for 5 minutes and then start it
again
If the problem continues, contact Xylem or the
Authorised Distributor
Stop the pump for 5 minutes and then restart it
again; if the problem continues, contact Xylem or
the Authorised Distributor
Check:
 the voltage
 the connection of the electric system
 Check for impurities near the impeller and rotor.
Remove them if necessary
 Check the conditions of installation,and the
water and air temperature
 Wait for the motor to cool down
 If the error persists, stop the pump for 5
minutes and then start it again
If the problem continues, contact Xylem or the
Authorised Distributor
Check the conditions of installation,and the air
temperature
Stop the pump for 5 minutes and then restart it
again; if the problem continues, contact Xylem or
the Authorised Distributor
Check if there are any leaks in the system and refill
the system
Check the water level in the system
Check the condition of the sensor connection
cables
Check the settings of parameters P45 and P46
