What to do if the Xylem Water Pump runs but the motor protection trips?
- G
  greerrobinAug 12, 2025
  If the Xylem Water Pump runs, but the motor protection trips, first, adjust the motor protection according to the data plate and cable chart, if applicable. If the impeller is difficult to rotate, clean the impeller and the sump, and ensure the impeller is properly trimmed. Also, check the fuses and replace any that have tripped. If the fuses are intact, contact a certified electrician.

What to do if Xylem Water Pump delivers too little or no water?
- K
  Kelly KnightAug 16, 2025
  If the Xylem Water Pump delivers too little or no water, first check the valves and reset any that are incorrectly positioned, replacing them if necessary. Ensure all valves are installed correctly according to media flow and open properly. Clean out any obstructions in the pipes and seal any leaks in the pipes and joints. If the impeller is difficult to rotate by hand, clean the impeller and the sump, and ensure the impeller is properly trimmed. If it is a 1-phase pump and the impeller rotates in the wrong direction, contact a sales or authorized service representative.

How to troubleshoot if the Xylem Water Pump does not start?
- A
  Arthur WilliamsonAug 20, 2025
  If the Xylem Water Pump does not start, and an alarm signal has been triggered on the control panel, make sure that the impeller rotates freely, the sensor indicators do not indicate an alarm, and the overload protection is not tripped. If the pump does not start automatically but can be started manually, verify that the start level regulator is functioning (clean or replace if needed), all connections are intact, the relay and contactor coils are intact, and the control switch (Man/Auto) makes contact in both positions. Check the control circuit and functions.

What to do if Xylem Water Pump starts-stops-starts in rapid sequence?
- J
  Joseph HerreraAug 25, 2025
  If the Xylem Water Pump starts and stops in rapid sequence, check that the distance between the start and stop levels is sufficient, the non-return valve(s) work(s) properly, and the length of the discharge pipe between the pump and the first non-return valve is sufficiently short. Also, check the contactor connections, the voltage in the control circuit, the functioning of the stop-level regulator, and whether the voltage drop in the line at the starting surge causes the contactor's self-holding malfunction.

What to do if Xylem Water Pump does not stop when a level sensor is used?
- W
  William JamesAug 27, 2025
  If the Xylem Water Pump does not stop when a level sensor is used, check for leaks from the piping or discharge connection, ensure the impeller is not clogged, verify the non-return valve(s) are functioning properly, and confirm the pump has adequate capacity. Additionally, clean the level regulators, check their functioning, inspect the contactor and the control circuit, and replace any defective items. If the stop level is set too low, raise it.

What to do if Xylem Water Pump installation is not receiving voltage?
- C
  Cassidy ChenAug 31, 2025
  If the Xylem Water Pump installation is not receiving voltage, check that the main power switch is on, there is control voltage to the start equipment, the fuses are intact, there is voltage in all phases of the supply line, all fuses have power and are securely fastened to the fuse holders, the overload protection is not tripped, and the motor cable is not damaged.
