What does alarm code A02 mean on my Xylem ecocirc XL?
If your Xylem Water Pump shows alarm code A02, it indicates a high temperature of the fluid. Check water temperature value.
Why is my Xylem Water Pump in Remote Off mode?
If your Xylem Water Pump is in Remote Off mode, it means that remote communication is deactivated. If the communication does not work, check the connection and the configuration parameters for communication on the external controller.
How do I check the power on my Xylem ecocirc XL Water Pump?
Check the power supply and ensure that it is properly terminated to the Xylem Water Pump power.
What does "ALOC" on my Xylem ecocirc XL display mean?
If your Xylem Water Pump display shows "ALOC", it means the rotor unlocking function is in progress. Wait for the result of this procedure, which usually takes about 30 seconds. If the procedure fails, error code E04 will appear.
How to troubleshoot a Xylem ecocirc XL Water Pump that has no power?
If your Xylem Water Pump isn't powering on, begin by checking the power connection to ensure it's properly connected. Also, verify the power supply and circuit breaker to rule out a power failure.
What does it mean when my Xylem ecocirc XL Water Pump displays error E04?
If your Xylem Water Pump displays error code E04 and does not start, it indicates a motor stall. Restart the pump.
What does error code E03 mean on a Xylem ecocirc XL?
If your Xylem Water Pump displays error code E03 and doesn't start, it indicates DC Bus overvoltage, suggesting excessive power. Confirm the system setup and verify the correct position and operation of check valves.
Why does my Xylem Water Pump's thermal protection trigger quickly?
If your Xylem Water Pump starts but the thermal protection is triggered shortly after, it could be due to several reasons: * Incorrect wiring size or a circuit breaker rating that's not suitable for the motor current. Check and replace the components as necessary. * Thermal overload protection due to excessive input. Check the pump's working conditions. * A missing phase in the power supply. Verify continuity and ensure proper wiring connections.
