1 Preparing and using for the first time T Hold the test strip briefly (for 1 second) under flowing water. Shake off the water. T Wait for about 1 minute. T You will then be able to read the degree of water hardness from the discolouration of the Aquadur® test strip and the description on the packaging. First-time use J WARNING If the machine is operated with a defective mains cable, there is a danger of potentially fatal electric shock.
1 Preparing and using for the first time T Touch the Coffee symbol > to confirm the water hardness setting. The Filter symbol ! and the Water Tank symbol M light up. T Open the water tank cover.

4 4 Permanent settings in programming mode Permanent settings in programming mode Automatic switch-off By instructing your D4 to automatically switch itself off, you can cut down your energy consumption. If this function is activated, your D4 switches off automatically after the preset time following the last action on the machine. The number of symbols that are lit up indicates the activated switchoff time: Switch-off time Symbol(s) shown in display 30 minutes The ; symbol lights up brightly.
4 Permanent settings in programming mode Setting the water hardness The harder the water is, the more frequently the D4 needs to be descaled. It is therefore important to set the water hardness accurately. The water hardness was set when the machine was first used. You can change this setting at any time. The number of symbols that are lit up indicates the set water hardness level: Level Water hardness The ; symbol lights up brightly. 1 – 15 °dH The ; and : symbols light up brightly.
5 5 Maintenance Maintenance Your D4 has the following integrated maintenance programmes: Cleaning the machine (L) Descaling the machine ( & ) U U E Proceed with the maintenance programmes when prompted to do so. Inserting/changing the filter Your D4 no longer has to be descaled if you are using the CLARIS Smart filter cartridge. E Once the filter cartridge stops working (depending on the water hardness setting), the D4 will prompt you to change the filter.
5 Maintenance E The water may be slightly discoloured. This is not harmful to health and does not affect the taste. Rinsing of the filter stops automatically. The light segment on the switch lights up. T Turn the switch to the ° position. Your D4 is once more ready for use. Cleaning the machine CAUTION After 180 preparations or 80 switch-on rinses, the D4 will prompt you to clean it.

7 7 Troubleshooting Troubleshooting Problem Coffee only comes out in drips when it is being prepared. Cause/Result The coffee is ground too finely and obstructs the system. Action T Set the grinder to a coarser setting (see Chapter 2 ‘Preparation – Adjusting the grinder’). The water hardness may not have been correctly set. The water tank float is trapped. T Perform descaling (see Chapter 5 ‘Maintenance – Descaling the machine’). Grinder is making a very loud noise.
8 8 Transport and environmentally friendly disposal Transport and environmentally friendly disposal Transport / Emptying the system Keep the packaging for your D4.
