Scale deposits naturally form in your coffee maker. Regular descaling helps protect your coffee maker and ensures it a longer life. It will also help maintain a quality of coffee that remains constant over time.
How often you descale your coffee maker depends on the hardness of the water and on how often you use your coffee maker. The following are tell-tell signs of scaling: the coffee making cycle takes longer, the appliance produces lots of steam, makes much more noise at the end of the cycle or stops during the cycle, this means that scale has built up in your coffee maker. You should descale your coffee maker between every 20 to 40 cycles or once a month depending on the hardness of the water.
Insulated carafes should never be put into the dishwasher! A plastic insulated carafe should be rinsed under hot water immediately after use. Never clean the carafe with a dishwashing brush or any other object as this may create hairline cracks that can cause the glass to implode. A brushed steel insulated carafe can easily be cleaned with a dishwashing brush or similar object, even inside.
• The quantity of ground coffee is too large. We recommend using one measure of coffee (7 grams) per mug. • The ground coffee is too fine ('Espresso' type ground coffee). • If you use a permanent filter, do not use a paper filter as well. • Certain types of paper filter (to make full-bodied coffees) can prolong the time in which it takes for the water to pass through the filter and ultimately cause the water to overflow.
After following the instructions in the user manual for starting the appliance, make sure that your electrical socket is working by plugging another appliance. If it still does not work, do not try to dismantle or repair the appliance yourself, instead, take it to an approved repair centre
This is entirely dependent on taste: you can buy pre-ground coffee for filter machines from supermarkets in a variety of strengths and flavours, you can grind your own coffee beans or you can buy beans at a coffee shop and ask for them to be ground to filter consistency.
