8. DESCALING
■ Why descale?
- Limescale naturally builds up in your coffee maker. Descaling helps to maintain your coffee maker so that it
lasts longer and offers constantly high coffee quality over time. Limescale can permanently alter the
performance of your machine. Malfunctions linked to scaling are not covered by the warranty if the product
is returned.
■ When to descale?
- The descaling frequency depends on the hardness of the water and the number of brew cycles. If you notice
the following signs: longer cycle time, excessive steaming, more noise at the end of the cycle, stopping mid-
cycle, your machine needs descaling.
- Your coffee maker should be descaled around once a month depending on the hardness of the water.
How to descale your KRUPS coffee maker
■ Use the KRUPS descaling solution®, or 17 fl. oz of white vinegar diluted in 17 fl.oz of cold or water at room
temperature, or 1.5 oz of citric acid diluted in 17 fl. oz until complete dissolution of crystals. Fig. 17.
■ Pour the solution into the water tank (without coffee). Fig. 18.
Start the cycle by pressing BREW (m). Half way through the cycle, switch off the machine and leave to
stand for one hour. After one hour start the second half of the cycle. Fig. 19.
■ Run 2 full 12 cups cycles with water and no coffee to rinse the machine. Fig. 20.
■ Repeat if necessary.
■ Coffee makers which work badly or stop working due to a lack of descaling are not covered by
the warranty.

it is in the "ON" position.
■ The water tank is empty.
■ There is a power outage.
■ Unplug the machine, then plug it back in.
■ The clock should be reprogrammed after a power outage.
■ The automatic stop feature has turned off the appliance. Turn off the
appliance and then turn it back on to make more coffee. For more
information, please consult the "Making Coffee" section.
■ Make sure the water tank has not been filled beyond the maximum
limit.
■ It may be time to descale the appliance.
■ Several minerals can accumulate in the coffee maker's circuitry.
Regular descaling of the machine is recommended. This may need to be
done more often depending on the hardness of your water. For more
information, please consult the "Descaling" section.
CAUTION: do not take the appliance apart.
