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.

What you seeWhat it means
Green power light and green Auto Off light on after you press powerHeating 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 blinkingNormal operation: The coffee maker is waiting for a size choice, after you lift and lower the handle.
The chosen size (and Strong) lit steadilyNormal operation: Brewing, which takes about 1 minute.
Strong and Small Mug (8 oz) lights blink 3 timesSetting 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 onSetting 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 onWater: 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 allOff 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.
