Q: What does the error code NC mean on the TALLAS D-ECONCEPT 1000 pump?

The error code NC on the TALLAS D-ECONCEPT 1000 pump means Blocked due to disconnected motor . This code appears when the pump detects that the motor is not properly powered or connected to the electrical system. Checks to perform: Check that the power cable is properly plugged into the electrical outlet (220-240 VAC / 50-60 Hz). Try unplugging and replugging the plug. Test the outlet itself with another electrical device to confirm that it is delivering power. Visually inspect all cables and connectors of the pump for damage, oxidation, corrosion, or partial disconnection. Ensure that all internal connectors (especially the motor connector) are properly in place and secure. Resetting the error: Once you have checked the power supply and connections, press the “+” and “-” buttons simultaneously and then release them. This operation resets the alarm. The red LED (Alarm) should turn off and the white LED (Power) should remain steadily lit. If the NC error persists after verifying the power cable and all connectors are checked and properly connected, it is likely an internal electronic fault of the speed controller or the motor itself. In this case, do not force the start and contact an authorized technical support center to diagnose and repair the pump.
