What to do if Xylem Flygt Concertor 6020 Water Pump delivers too little or no water?
- D
  Diane WilliamsAug 3, 2025
  If your Xylem Water Pump is not delivering enough water or no water at all, make sure that all valves are in the correct positions. Reset or replace any valves that are incorrectly set and verify they are installed correctly according to the media flow and open properly. Also, ensure that the impeller rotates freely. Clean the impeller and the sump. Check that the impeller is trimmed correctly. To ensure a free flow, clean the pipes. Find the leaks in pipes and joints and seal them. Replace the worn parts on the impeller, pump, and casing. Check that the level sensor is set correctly. Depending on the installation type, provide equipment for the pump priming, for example, a foot valve.

  William BennettAug 13, 2025
  If your Xylem Water Pump isn't starting, it might not be receiving voltage. Verify that the main power switch is on, the fuses are intact, there's voltage in all phases of the supply line, all fuses have power and are securely fastened, and the motor cable isn't damaged.

What to do if Xylem Water Pump starts but stops after 10 seconds?
- M
  Mr. Carl GrahamAug 18, 2025
  If your Xylem Water Pump stops shortly after starting (approximately 10 seconds), the FLS might be triggering the sum alarm due to leakage into the drive unit. To check this, turn the power off and on to restart the pump. If it stops again after 10 seconds, disconnect the pump and empty any liquid from the drive unit. If the pump behaves differently, further diagnostics are needed.

Why does my Xylem Flygt Concertor 6020 Water Pump start, stop, and start again rapidly?
- N
  Nicholas CollierAug 23, 2025
  If your Xylem Water Pump starts and stops repeatedly in quick succession, back-flow might be the issue, causing the sump to refill to the start level. Check that the distance between the start and stop levels is sufficient, the non-return valves are working correctly, and the discharge pipe between the pump and the first non-return valve is sufficiently short. Another potential cause is malfunction of the contactor's self-holding function. Inspect the contactor connections, the voltage in the control circuit, the functioning of the stop-level regulator, and the voltage drop in the line during startup.

  If your Xylem Water Pump isn't receiving commands from the gateway, there might be a communication issue. Check the gateway's power supply, ensure the PUMP COMMS indicator is lit, restart the gateway, and check T3 and T4.
