DESCALING
If the water in your local area is hard, lime scale
will form over time. These deposits may affect the
correct operation of the appliance.
When the pilot light (10) starts flashing, the machi-
ne needs to be descaled. The descaling process
may be performed using special commercially-
available scale removers for drip coffee makers.
Alternatively, white wine vinegar can be used as
follows:
1. Remove the chlorine filter.
2. Pour 2 cups of white wine vinegar and 3 cups
of water into the tank. Place the tank in the
coffee maker;
3. Place the carafe on the warming plate, do not
put any ground coffee in the filter holder;
4. Press the drip coffee ON/OFF button,
percolate the equivalent of one cup and then
button off the appliance;
5. Leave the vinegar to sit for one hour;
6. Switch the coffee maker back on and percolate
the rest of the solution;
7. To rinse the machine, operate it with water and
without ground coffee at least 3 times (3
complete tanks of water).
Once the descaling operation is complete, press
the “HOUR” and “MIN” buttons together to switch
off the pilot light.
