Not Ready — heating in progress
The brewer is heating water to brew temperature and isn't ready to start a cycle yet. Normal on first power-up or after Auto Off — typically clears in 1-3 minutes. If it persists more than 5 minutes, a heater fault is likely.

The fix
Keurig Descaling Solution
Normal heat-up cycle, unless it never clears — then scale-insulated heater
Diagnose first: Only relevant if Not Ready persists past 5 minutes or returns after a power-cycle reset. In the vast majority of cases this clears on its own in 1-3 minutes and no purchase is needed.

How to fix it
- Wait 2-3 minutes for the brewer to finish heating
- Listen for the heater clicking off and the ready light
- If 'Not Ready' persists past 5 minutes, unplug for 5 minutes and retry
- If still stuck after a reset, descale to remove scale insulating the heater
- If still stuck after descale, the heater has failed
