ter for espresso coffee are not obstructed. If necessary, carefully clean the filter with hot water, scrubbing with an abrasive pad.

DESCALING

If the water in your area is quite hard, the calcium from this water can accumulate and reduce the machine’s efficiency.

The espresso coffee machine must be decalcified every 1-3 months (depending on the hardness of the water and the frequency of use) using white wine vinegar. Proceed as follows:

•Fill the carafe for espresso coffee with vinegar to level 4 of the ‘water level’ side.

•Pour the vinegar into the steam boiler and replace the cap.

•Attach the filter holder.

•Place the small carafe under the filter holder;

•Turn the machine on and position the Vario System selector to the “LIGHT” position.

•After a few minutes, the hot vinegar will begin to flow, through the filter holder, into the carafe. Release some steam every so often by turning the steam release knob.

•When all of the solution has gone through the machine, turn off the appliance and let it cool down.

•Repeat these operations at least two times using clean water instead of vinegar to remove every trace of vinegar left in the circuits.

The filter coffee machine must be decalcified every 40 cycles. Descaling can be done by using special lime scale solvents made for filter coffee machines. Alternatively, white wine vinegar can be used, fol- lowing this procedure:

•Pour two cups of white wine vinegar and three cups of water into the tank.

•Place the large carafe onto the hot plate but leave the filter empty.

•Press the ON/OFF drip coffee switch, filter the equivalent of a cup of the solution and then turn off the appliance.

•Allow the vinegar to sit in the machine for an hour.

•Turn the machine back on and allow the rest of the solution to filter through the circuits.

•To rinse the appliance, operate the machine with plain water and without using ground cof- fee at least 3 times (3 full tanks of water).
