Maintenance - ECM TECHNIKA V Profi PID Bedienungsanleitung

For preventive decalcification, please proceed as follows:
It is recommended to unscrew and remove the nozzle of the hot water dispenser so that no dirt can
accumulate inside the nozzle.
If you use your machine with direct water connection, the machine must first be switched to water
tank operation.(chapter 4.3.1)
1 Heat up the machine until the operating pressure has been reached (1.0-1.2 bar).
2 Switch the machine off.
3 Empty the boiler by operating the hot water dispenser. Then close the hot water dispenser again.
4 Mix the descaler with water according to the instructions and put it into the water tank.
5 Switch the machine on. The empty boiler is automatically filled with descaling liquid.
6 Operate the group lever and wait until liquid is released from the group. Thus, the heat exchanger is filled with
descaler liquid.
7 Allow approx. 300 ml to flow out of the brew group into a container.
Let the descaler work for approx. ½ hour in the heated machine.

9 Switch the machine off and empty the boiler by dispensing hot water. Then close the hot water valve again.
10 Rinse the water tank and remove lime or descaler residues.
11 Fill the water tank with fresh water.
12 Switch the machine on. Thus, the boiler will automatically be filled with fresh water.
13 Fill the water tank with fresh water.
14 Operate the group lever for approx. 60 seconds to rinse the heat exchanger.
15 Repeat point 9 to 11 five to seven times in order to rinse the boiler until clear, neutral smelling water comes out of
both the group head and the hot water release.
Important
These descaling instructions are only meant for prophylactic descaling. Please do not descale the
machine if it is already calcified. While descaling the machine, the lime residues can cause blockages in
several components, such as valves, gauges etc., causing damage to your espresso coffee machine. In
this case, please contact your specialised dealer. It is probable that a professional descaling has to be
carried out which requires the disassembling of boiler and tubing.
Damage to persons or to the material, caused by calcification in and on your machine, is not subject to
the manufacturer's liability.
In this case, the warranty expires as well.
