Not universally. The appliance manual, tablet instructions and actual water conditions determine how the softening and rinse-aid arrangements should be used.
Understanding this situation
A marketing description cannot override the model's requirements. Some conditions still call for separate products, while settings differ across machines, so copying a neighbour's setup may be misleading.
A useful next step
Check the exact guidance before disabling reminders or leaving reservoirs empty. If marks or drying change after switching tablets, record the product and settings. Do not assume a persistent warning is meaningless merely because the packet says all-in-one.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
