Cleaning Instructions
Daily cleaning:
To ensure food safety and proper
•
operation, empty the drip tray as needed and
wash in a solution of dish detergent and water,
rinse thoroughly.
All external surfaces can be cleaned with a soft,
•
damp cloth. Do not use any abrasives. They will
scratch the external surfaces.
Do not place brewer or individual parts into a
•
dishwasher.
Weekly cleaning:
Remove and empty the reservoir tank and wash in
•
a solution of dish detergent and water, rinse
thoroughly.
Ensure surrounding surfaces and under the brewer
•
are cleaned regularly to prevent the attraction of
vermin and bacteria growth from spilled coffee
and sugars.
Draining:
This action will clear water from the brewer. Do not
place brewer or individual parts into a dishwasher.
1. Power off brewer. Allow brewer to cool. Close water
supply valve (Auto-Fill only) and disconnect water
line.
2. Remove and empty reservoir.
3. Remove back panel, uncap drain line and drain tank.
Recap and replace back panel.
4. Turn on brewer.
5. Place a cup under the brew chamber, hold down
reservoir detection switch and start a brew
sequence.
6. Continue brew sequence until water stops flowing
into the cup or until Water Flow Error is displayed.
Descaling:
This action will help remove hard water
deposits.
Process will take approximately 3.5
hours
and requires 72 oz. of distilled vinegar. Do not
place brewer or individual parts into a dishwasher.
The frequency of descaling depends on the level of
mineral content of your water. This is why we
recommend using filtered or bottled water. Calcium
deposits or scale may build up in your brewer and
hinder your brewer performance. Regularly descaling
your brewer every 3 to 6 months helps prevent this
from occurring; however, if you feel that your water
has a higher level of mineral content, then you should
consider descaling more often.
If the action screen has a
red exclamation mark, call
service provider. If it is
yellow, user action is
required.
CAUTION
Brew probes are sharp. To prevent injury, do not place
fingers inside the brew chamber. To reduce foreign
material from entering the brewer, keep brew
chamber and reservoir lids closed.
DANGER
To prevent electrical shock, do not immerse machine
in water.
