The lime-scale removal programme
The amount of lime-scale deposited is dependent on the hardness of the
water used. When it is necessary to carry out lime-scale removal, you will be
warned of this when the appliance is switched on by the glowing of the
“remove lime-scale” indicator.
Note: You can continue to use the appliance, but should carry out the
lime-scale removal programme as soon as conveniently possible.
Caution! Use only KRUPS lime-scale removal agent or citric acid or
tartaric acid. No responsibility can be taken for eventual damage arising
from the use of other materials. You can obtain lime-scale removal
materials from the KRUPS service unit.
Do not under any circumstances use the conventional amidosulphonic
acid or any materials containing such acid, as this can damage your
appliance. Carefully check the composition of any lime-scale removal
materials which you propose to use.
Carrying out the lime-scale removal programme
During the lime-scale removal process, the “ON/OFF” indicator will glow.
The “remove lime-scale” indicator will blink while the appliance is working
and will glow if and when the removal programme is stopped.
The mains plug must be inserted, but the appliance must be switched off.
The selector knob for steam/hot water must be at the position.
■ Start the lime-scale removal programme by
pressing the key for about 3 seconds (31).
The “ON/OFF”, “empty spent coffee holder”
and “remove lime-scale” indicators will glow,
as will also the “fill water tank” indicator if
there is no or very little water in the tank.
■ Empty the drawer and the spent coffee holder
and return them to the appliance.
■ If necessary, empty the water tank.
■ Dissolve 4 level tablespoonfuls (about 40 g) of the lime-scale removal
material in 1/2 a litre of lukewarm water and pour the solution into the
water tank.
■ Replace the water tank.
The “ON/OFF” and “steam” indicators will blink.
■ Place a sufficiently large receptacle (at least 300 ml capacity) beneath the
steam pipe.
