Mineral buildup can contribute to slower flow or maintenance alerts, but those symptoms can have other causes.
What to do
Review alerts, water-hardness settings and descaling history. Check the manual before starting a cycle.
Safety and when to seek help
Persistent faults may need diagnosis rather than repeated chemical treatment.
Keep a simple maintenance record
Record the date of cleaning or descaling, any maintenance alerts, filter changes and symptoms that return. This information can help you explain the issue if you later request a service assessment.
