What does CODE ERROR mean on my Xylem HVL 2.015-4.220 Water System?

If you encounter CODE ERROR on your Xylem Water System, it indicates an invalid processor command. Ensure the installation of the cables, the screen connection, and potential equalization are correct. Also, verify that the ground is correctly installed and that the signal is strong enough; if not, install additional ferrite inductances to boost the signal.
