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
E05 EEPROM Data
memory error EEPROM Data memory corrupted Stop the pump for 5 minutes and then restart it
again; if the problem continues, contact Xylem or
the Authorised Distributor
E06 Grid voltage error Voltage supply out of operating
range Check:

the voltage

the connection of the electric system
E07 Motor winding
temperature error Motor thermal protection trip

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
