De-Scaling Your Brewer
Depending on the mineral content of the water, calcium deposits or scale
may build up in your Brewer. Scale is non-toxic but left unattended, it can
hinder Brewer performance. De-scaling your Brewer helps maintain the
heating element and other internal parts of the Brewer.
The Brewer should be de-scaled every 3-6 months to ensure optimal
performance or when there are white deposits in the Cold Water Reservoir.
It is possible for calcium deposits to build up faster, making it necessary to
de-scale more often.
A. PREPARE
You will need 20 oz. of undiluted white vinegar, a 12 oz. ceramic mug (do not
use a paper cup) and access to a sink.
B. FiLL AND CLEAN
Step 1:
Fill the Cold Water Reservoir with 10 oz. of undiluted white vinegar to
the 10 oz. mark on the Water Level Guide.
Step 2: Place the ceramic mug on the Drip Tray Plate. Lift and lower the
Brewer Handle completely and perform a brew without adding a
K-Cup. Empty the contents of the ceramic mug into the sink.
CAUTION: Be careful as contents will be hot.
Step 3: Place the ceramic mug back on the Drip Tray Plate. Pour the
remaining 10 oz. of vinegar into the Cold Water Reservoir. Start a brew,
but power off the Brewer just after it starts to dispense. Allow it to sit
for at least 30 minutes.
C. RiNSE
Step 1:
After the prescribed period of time (at least 30 minutes), turn your
Brewer on and place the ceramic mug on the Drip Tray Plate. Lift and
lower the Brewer Handle completely and perform a brew without
adding a K-Cup. Empty the contents of the ceramic mug into the sink.
CAUTION: Be careful as contents will be hot.
Step 2: Fill the Cold Water Reservoir with 10 ounces of fresh water, place
the ceramic mug on the Drip Tray Plate and perform a brew without
adding a K-Cup.
Step 3: Repeat Step 2 three times to cleanse the Brewer plumbing and get rid
of any residual taste from the vinegar. The Brewer is now ready for
normal use again.
