Coffee Systems

User Settings

The Grind’n Brew® has several factory-set options that can be modified by the user.  These are divided into two 
categories:  Universal Settings or Brew Settings.  Universal Settings pertain to the whole unit, and Brew Settings
pertain to one of the four available brew cycles – (Regular Full, Regular Half, Decaf Full and Decaf Half).  All 
settings are retained during a power loss.  The original factory settings can be restored by using the 

System

Pulse Brew Cycle

Pulse Brewing is a feature that increases the control and performance of the Grind’n Brew® machine.  By pulsing
water during the brew cycle, you allow greater contact time and better extraction of the coffee.  Ultimately you will
achieve a bolder and more consistent cup of coffee by using this feature.

If pulse brewing is selected, the unit will brew the number of pulses identified by the 

Pulse Brew Pulses

setting.

Each pulse is identical.  It will begin by dumping water for the 

Pulse Brew Pour Time

and then wait for the 

Pulse

Brew Delay Time

.  This will repeat until all pulses are finished.

Once the pulses are complete, the unit will pour water for the remaining 

Brew Time

.  

Brew Time

is the total amount

of time water is poured over the coffee grinds.  

Pulse Brew Pour Times

are included in this total.  

Pulse Brew

Delay Times

are not included.  The cycle will always stop pouring once the 

Brew Time

is met, regardless of

whether this happens in the middle of pulse brewing.

Drip Time

is half of the 

Brew Time

.  However, the 

Drip Time

will never be greater than 1:30.

Bean Counter

The built-in bean counter measures relative usage of its Grind’n Brew® machine by totaling the amount of seconds
the augers have fed beans into the grinder.  This number directly correlates to the amount of beans used by the
machine.  

Depending on model, the bean counter is either always shown or hidden to the user.  

The 

Bean Counter Menu

is accessed by holding the 

UP

and 

DOWN

keys for 5 seconds.  If the counter is normally

hidden, it will be shown here.  The user can reset the counter through this menu.  Pressing the 

SET

button will 

display “

REs

” and the user can select “

YEs

” or “

no

” with the 

UP

and 

DOWN

keys.  Pressing the 

SET

key finalizes

the selection.  This menu times out after 10 seconds and is disabled by the 

User Lockout Jumper

.
