De-Scaling Your Brewer
Mineral content in water varies from place to place. Depending on the mineral content of the water in
your area, calcium deposits or scale may build up in your brewer. Scale is nontoxic, but left unattended,
it can hinder brewer performance. De-scaling your brewer helps maintain the heating element and other
internal parts of the brewer that come in contact with water.
The brewer should be de-scaled every 6 months to ensure optimal performance. It is possible for
calcium deposits to build up faster, making it necessary to de-scale more often.
This brewer is equipped with sensors to detect when scale buildup is interfering with the performance of
the brewer. When this is detected, the brewer will alert you to perform a de-scaling procedure by
generating one of the following messages.
• De-scale soon
• De-scale now
NOTE: SAFETY GLASSES AND RUBBER GLOVES SHOULD BE WORN BEFORE
PROCEEDING WITH THE DE-SCALING PROCEDURE.
5. De-Scaling Procedures:
a) PREPARE
1. Make sure you have at least (80 ounces) of full strength citric acid such as CDCC Citric Acid
Powder or similar product on hand. You will also need an empty sink and a ceramic cup (do
not use a paper cup.) and a Flojet pump or similar.
2. Disconnect the brewer from the water supply and power it off. Drain both the hot and cold
tanks.
b) FILL AND CLEAN
1. Enter the PRIME mode (enter Menu mode and answer YES to HAS BREWER BEEN
DRAINED) and use a Flojet pump system to add de-scaling solution to the brewer.
NOTE: The water temperature for dissolving the powder can not be greater then 110° F.
Damage to the Flojet pump can occur.
Complete the PRIMING process.
2. After it has primed and heated, place a ceramic cup in the Drip Tray and run a brew cycle.
DO NOT USE A K-CUPP® Pportion pack, just press the Brew Button. Pour the contents of
the cup into the sink.
3. Now let the brewer stand for at least one hour.
4. Repeat the brew process, without K-Cups® at least 10 times, pouring the contents of the cup
into the sink after each cycle. We suggest using the largest brew size to speed the process.
Remember to open and close the brew handle between each cycle so the blue Brew lights
will flash.
