6 - TROUBLESHOOTING

Problem Troubleshooting/Solution Advice

No steam output from the wand	The tip of the steam wand is clogged; unclog it with needle. This problem is caused by the way the tip is put into the milk.	Clean the steam tip after each use.
Leaks from filter holder Possible causes:1 - The group head gasket is worn or encrusted.2 - The filter holder is incorrectly inserted in the group.		Clean it using the brush supplied.Should the problem occur again, call a specialised technician
Difficulty in inserting the filter holder on the group head	The problem can be caused by an excessive dose of coffee in the filter holder.	Decrease the quantity of coffee in the filter holder. (The standard doses x filters are 10 g per dose.)
Incorrect position of the filter holder once inserted in the group	Once inserted on the group, the handle of the filter holder has shifted to the right. The group head gasket is worn.	Call a specialised technician to replace the group head gasket.
The flow of coffee is scarce	The coffee is dispensed drop by drop, the output time is too long and the quality of it is not good, the cream is dark.Possible causes:1 - The coffee is ground too finely.2 - The coffee has been pressed too firmly in the filter holder.3 - The dose in the filter holder is excessive.4 - The group shower head is clogged.5 - The filter holder filter basket is clogged.6 - The pressure delivered by the pump is low (< 9 bar - 0.9 MPa), or is not working.	In cases 1-2-3, the problem can be solved by adjusting the grinding and/or dosing.In cases 4-6, contact a technician.In case 5, clean or replace the filter.

Problem Troubleshooting/Solution Advice

The flow of coffee is excessive	The coffee is dispensed too quickly and the cream is lighter than usual.Possible causes:1 - The coffee is ground too coarsely.2 - The coffee in the filter holder has not been pressed firmly enough.3 - The dose in the filter holder is too small.4 - The pressure delivered by the pump is too high (>10 bar - 1 MPa).	In cases 1-2-3, adjust the grinding and/or dosing of coffee.In case 4, contact a technician.
The coffee dispensed is too cold	Possible causes:1 - The filter holders are cold.2 - The coffee is ground too finely.3 - The machine water circuit is dirty (lime-scale).4 - The boiler pressure is lower than 0.8 bar (0.08 MPa).	In the 1st case, keep the filter holder inserted on the group.In the 2nd case, adjust the coffee grinding.In cases 3-4, call a specialised technician.
The coffee dispensed is warm	The coffee dispensed is warm even if the pressure is normal, between 1 and 1.2 bar (0.1 – 0.12 MPa). In this case, the pressure detected is false.	Call a specialised technician to check the bleed valve. Meanwhile, to use the machine, open the steam tap (Fig. 01; pos. 9); the boiler's pressure will drop to zero, thus activating the resistor and increasing the temperature. Perform this operation daily when turning on the machine.
The coffee dispensed is too hot	Possible causes:1 - The boiler pressure is higher than 1.3 bar (0.13 MPa).2 - The machine is covered by something that prevents it from cooling.3 - The machine was installed in a position that does not allow air circulation.	In the 1st case, call a specialised technician.In the cases 2-3, reset the machine cooling conditions.
Coffee deposits on the bottom of the cup	Possible causes:1 - the coffee is ground too finely.2 - the filter holder is dirty inside or the filter is damaged.3 - The grinding discs are worn.4 - High pump pressure (> 10bar - MPa).	Case 1 can be solved by adjusting the grinder correctly.In case 2, clean the filter holder or replace the filter.In cases 3-4, contact a technician.
