The actual water conditions and appliance arrangement may differ at the new address. A dose or hardness setting copied from the previous home may no longer match the instructions.
Understanding this situation
Use reliable supply information and account for any household treatment system. A town name alone is not a precise measure, and changing several settings blindly makes later comparison difficult.
A useful next step
Review the exact model and product guidance after installation. Record any supported adjustments and ordinary results. If a fault or leak appears after the move, report the installation history separately rather than attributing everything to water hardness.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
