DESCALING THE DRIP COFFEE SECTION Over time, the lime contained in the water will cause blockage that can prevent the machine from working properly. The coffee machine is equipped with a system for controlling the amount of lime. When the lime reaches a high level, the drip coffee ON light begins to flash: this means it is time to descale. To descale, proceed as follows: 1. Fill the carafe with clean cold water up to the 4 cup level. 2. Dissolve 2 spoonfuls (about 30 grams) of citric acid (sold at drugstores) in the water. 3. Pour the solution into the tank and place it in the machine. 4. Remove the filter from the filter-holder (to avoid contamination). 5. Place the carafe with the lid on the warming plate. 6. Press the DRIP COFFEE ON/OFF button and let one cup of solution run into the carafe; then turn off the machine. 7. Leave the solution to work for one hour. 8. Turn the appliance back on and let the rest of the solution percolate through. 9. To rinse, run the machine with water only (no ground coffee) at least three times (three full water tanks). Repair of damage to the coffee machine caused by lime scale is not covered by the warranty if descaling is not performed regularly as described above. PROBLEM No espresso coffee is delivered. No milk froth is formed when making cappuccino. The drip coffee takes longer to brew. The coffee has an acidic taste. POSSIBLE CAUSES •The coffee is ground too finely. • The holes in the filter-holder spouts are obstructed. • The filter is clogged. • The milk is not cold enough. • The splash hood is dirty. • The drip coffee machine needs to be descaled. • Inadequate rinsing. SOLUTION • Use medium grind coffee or coffee ground expressly for espresso makers. •Clean the spout holes. • Clean the filter and holes thoroughly using a pin (see Fig. 32). • Use reduced fat (or preferably fatfree) milk at refrigerator temperature. • Clean the splash hood thoroughly. • Descale as described in the section DESCALING THE DRIP COFFEE SECTION. • Rinse the appliance as described in the section DESCALING THE DRIP COFFEE SECTION. 12
