Keurig K-Select: what the lights mean
Single-serve K-Cup pod brewer
The K-Select has four brew-size buttons, a Strong button, a green power light, a green Auto Off light and an Add Water light, and no screen. Its guide uses the button lights for two hidden settings as well as for brewing: Auto Off (a 2-hour switch-off you can disable) and High Altitude Brewing Mode, which is confirmed by two lights blinking three times. Keurig’s own Canadian guide is the one read here; it gives sizes in ml and oz.
Every Keurig K-Select light we could source
| What you see | What it means |
|---|---|
| Green power light and green Auto Off light on after you press power | Heating up: The coffee maker is on and heating, which takes about 3 minutes; when the heating sound stops it is ready. |
| The four brew buttons and Strong blinking | Normal operation: The coffee maker is waiting for a size choice, after you lift and lower the handle. |
| The chosen size (and Strong) lit steadily | Normal operation: Brewing, which takes about 1 minute. |
| Strong and Small Mug (8 oz) lights blink 3 times | Setting confirmed: High Altitude Brewing Mode has been turned on — the setting Keurig gives for use at 1,500 m (5,000 ft) and above. |
| Green Auto Off light not lit while the coffee maker is on | Setting confirmed: Auto Off is disabled: the coffee maker will stay on instead of switching itself off 2 hours after the last brew. |
| Add Water light on | Water: The brewer wants water: the reservoir is low or empty, or it is not sitting properly on its base, and it will not brew until that is fixed. |
| No lights at all | Off or no power: The coffee maker is off — with Auto Off enabled it switches itself off 2 hours after the last brew — or it is not getting power. |
