Cleaning

Descaling the Water Reservoir and Hot Water Tank
Regular descaling will prolong the life of your brewer and will guarantee
optimal brewing results for a long time. If the machine is used twice a day on
average, it must be descaled once every 3 months.
Step 1:
Fill one-fourth of the water reservoir with white vinegar, then fill with clean
tap water up to the MAX line.
Step 2:
Place a 32 ounce (1 L) container on the cup grate to catch the vinegar/water
cleaning solution.
Step 3:
Activate the manual prime feature. Press and hold down the BREW button
until approximately 9 ounces (266 ml) of water has been dispensed from
the brewer.
Step 4:
Repeat step (3) two more times, making sure there is still sufficient cleaning
solution supply in the water reservoir each time.
Step 5:
The unit will then heat up normally and the BREW button will turn green,
indicating that the water has reached the brew temperature. After one
minute, the button will turn yellow.
Step 6:
Wait 10 minutes, allowing the brew temperature water to sit in the tank.
Step 7:
Refill the water reservoir with cool, clean, tap water to the MAX line.
Step 8:
Repeat steps 2, 3 & 4, using the water that you added in step 7, to purge
the cleaning solution from the system.
Step 9:
Refill the water reservoir to the MAX indicator line and the unit will be ready
to brew coffee or tea.
