5.3 Descaling
The device has to be descaled regularly, otherwise the coffee taste will be affected and the
scale deposits can damage the device.
When the noise during brewing increases, or the brewing time is longer, or the device
switches off before the water tank is empty, then these are indications that descaling is
necessary.
The frequency of descaling depends on the water hardness and how often the device is
used.
- With soft water, descale at least every 3 month
- With hard water, descale every month
If you do not know your water hardness please contact your water company.
Use a liquid descaler that is suitable for coffee machines and read the instructions
thoroughly before use.
1. Mix the descaler in a measuring cup with cold water.
In case of using solid descaler/powder, it must dissolve completely.
2. Fill the water tank with the prepared solution up to max level.
3. Turn the control dial to setting for ground coffee, place the jug and press start button
as if you want to brew coffee.
4. Repeat steps 1-3. Do not refill the used solution after brewing process into the water
tank again, use a fresh solution.
5. Operate 2 brewing cycles only with water (without descaler) to remove all descaler
residues.
Please note
► Never interrupt the descaling process.
► The guarantee excludes devices which have stopped working or do not work properly
due to lack of descaling.
