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.
