Residue around the group head can affect hygiene and may contribute to off flavours.
What to do
Use the manual for brushing accessible areas and cleaning compatible baskets. Backflush only if the machine supports that process.
Safety and when to seek help
Avoid tools in hot or pressurised components.
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.
