| Problem | Solution |
|---|---|
| The appliance does not work. | Put the mains plug in the wall socket. Make sure that the voltage indicated on the appliance corresponds to the local mains voltage. Fill the water reservoir with water. |
| When I use the grinder, the coffee is too weak. | Make sure the number of cups you select with the 2-10 cups button is consistent with the amount of water in the water reservoir. Please keep in mind that the appliance uses all the water in the water reservoir. Use the STRENGTH button to set the coffee strength to 'strong' . When you use coffee beans, make sure you do not press the preground coffee button, as this switches off the grinder. Use beans of a stronger blend or flavour. To increase the coffee strength, select a higher number of cups with the 2-10 cups button than the number of cups you fill the water reservoir with. |
| When I use pre-ground coffee, the drink is too weak. | Make sure the amount of pre-ground coffee in the filter is consistent with the amount of water in the water reservoir. Please keep in mind that the appliance uses all the water in the water reservoir. Use ground beans of a stronger blend or flavour. To increase the coffee strength, increase the amount of pre-ground coffee or decrease the amount of water. |
| I have set the coffee strength to 'strong' with the STRENGTH button, but the coffee is too weak. | When the grinder is switched off, you cannot change the coffee strength with the STRENGTH button. In this case you can only increase the drink strength by increasing the amount of pre-ground coffee or decreasing the amount of water, or by using beans of a stronger blend or flavour. |
| The filter overflows when I remove the jug from the appliance while it is brewing coffee. | If you remove the jug for more than 20 seconds during the brewing process, the drip stop causes the filter holder to overflow. Also note that the drink does not reach its full taste before the end of the brewing process. Therefore we advise you not to remove the jug and pour out the coffee before the end of the brewing process. |
| The appliance continues to drip long after the brewing process has ended | The dripping is caused by condensation of steam. It is completely normal that the appliance drips for some time. If the dripping does not stop, the drip stop may be clogged. To clean the drip stop, push it to open it and then rinse it under the tap. If you remove the jug for more than 20 seconds during the brewing process, the drip stop causes the filter basket to overflow. |
| The coffee is not hot enough. | Place the jug properly on the hotplate. Make sure that the hotplate and the bottom of the jug are clean. Use thin cups, because they absorb less heat from the coffee than thick cups. Do not use milk that comes directly out of the fridge. Descale the appliance. |
| Problem | Solution |
|---|---|
| The coffee is not hot | The cups have not been preheated. • Pre-heat the cups by rinsing them in hot water or leaving them for at least 20 minutes on the cup warmer tray • The infuser is too cold. Heat the infuser by pressing the *button (see under the table) button before making the coffee. |
| The coffee is not creamy enough | • The machine uses too little coffee during the infusion process. Turn the grinding quantity selector knob a little clockwise. • The coffee is ground too coarse. Turn the grinding adjustment knob one click anticlockwise. • Wrong type of coffee. Use a type of beans for fully automated espresso makers. |
| The coffee comes out too slowly | • The coffee is ground too fine. Turn the grinding adjustment knob one click clockwise. • The machine uses too much coffee during the infusion process. Turn the grinding quantity selector knob a little anticlockwise. |
| The coffee comes out too quickly | • The coffee is ground too coarse. Turn the grinding adjustment knob one click anticlockwise. • The machine uses too little coffee during infusion. Turn the grinding quantity selector knob a little clockwise. |
| The coffee does not come out of one of the spouts | • The outlet is blocked. Scrape the remains of dry coffee accumulated with a needle |
| Turning the steam knob, no steam comes out of the milk frother | • The holes in the spouts are clogged. Clean the holes in the milk frother and the milk frother nozzle. |
| Pressing the 1 cup or 2 cups button the machine does not deliver coffee, but only water | • Ground coffee may be blocked in the funnel. Remove the ground coffee inside the funnel, using a knife. Then clean the infuser and the inside of the machine. |
| Pressing the 'Start' button, the machine does not switch on | • The machine is not plugged in. Check that the power cable is plugged into the power outlet. |
| The infuser cannot be removed for cleaning | • The machine is on. The infuser can only be removed if the machine is off. Turn the machine off. Attempting to remove the infuser with the machine on will risk causing damage. |
| Ground coffee is used (rather than beans) and the machine does not deliver the coffee. | Too much ground coffee has been added Remove the infuser and thoroughly clean the inside of the machine. Repeat the operation using a maximum of 2 level measures of ground coffee. |
| The coffee does not come out of the spouts, but rather around the service door | • The holes in the spouts are clogged with dry coffee. Scrape the holes with a needle. • The mobile drawer inside the service door is blocked and cannot swing. Thoroughly clean the mobile drawer,above all near the hinges, so that they swing smoothly |
