Keurig KB31 owner manual Cleaning the Cold Water Reservoir, Emptying the Internal Hot Water Tank

SECTION 5 Cleaning & Maintenance (continued)

Cleaning the Cold Water Reservoir

It is normal over time for discoloration, spotting or staining to appear in the Cold Water Reservoir. Results will vary depending on the mineral content of the bottled or filtered water used but will not affect the operation of the Brewer. However, be sure to clean the Cold Water Reservoir regularly to minimize build-up.

To access the Cold Water Reservoir, lift the lid. Remove the Water Level Guide (fig. 5) and then clean inside the reservoir with a damp, lint-free cloth as necessary (fig. 6).

Replace the Water Level Guide and lower the lid when finished.

The Water Level Guide is not dishwasher safe.

Emptying the Internal Hot Water Tank

Brewer must be powered off but plugged in.

•Lower the Cold Water Reservoir Lid.

•Place a mug on the Drip Tray.

•Press and hold down the BREW Button and continue to hold until all the water is dispensed into the mug.

There will be a 3 to 5 second delay before water begins to dispense.

De-Scaling Your Brewer

Calcium deposits may build up in your Brewer, depending on the mineral content of your water. Scale is non-toxic but if left unattended, it can hinder Brewer performance. De-scaling your Brewer helps to maintain the heating element and other internal parts of the Brewer.

The de-scaling process should be done every 3 to 6 months to ensure optimal performance or when there are white deposits in the Cold Water Reservoir. However, it is possible for calcium deposits to build up faster, making it necessary to de-scale more often.

To begin, you will need the following:

•20 oz. of undiluted white vinegar

•12 oz. ceramic mug (do not use a paper cup)

•Access to a sink
