Keurig describes descaling as removal of calcium deposits that can hinder brewer performance and recommends it every three to six months or, for selected brewers, when the light appears. That maintenance reminder does not establish the right buttons, quantities, or finish condition for every model.
| Record before repeating a cycle | Why it helps |
|---|---|
| Exact brewer model | Descale Mode and completion steps can differ by model. |
| Whether the full fresh-water rinse completed | Separates an interrupted routine from a persistent indicator. |
| What still fails after rinsing | Helps support distinguish a light from flow, pump, or control symptoms. |
