The problem might be casued by a faulty electric board, which is unfortunately rarely repairable.

In case You can't or don't want to resolve the problem with the tips above, then the machine needs the attention of a professional.

Not heating up

Unfortunately all possible causes need the attention of a professional.

Thermostat(s)

Some thermostats need to be reactivated after a possible overheating of the machine, while they can also go in case of an extreme overheating issue.

Temperature sensor

Although rarely, but the temperature sensor can cause this fault as well.

Electric board

Ocasionally faulty triacs and varistors can cause such a symptom.

Burnt smell

Unfortunately all possible causes need the attention of a professional.

Electric components

Almost any electric component can cause burnt smell.

Electric board

Burnt smell mainly arises from faulty electric boards.

Lights / error messages

Prime the circuit, ventilate

This message means that there was a problem with the water flow rate and the machine automatically tries to fix the problem by letting water through the system. If it is not successful, then the cause might be a a blockage in the water system or the brew unit, or a misplaced water tank.
The machine will automatically let water through abd try to fill the water system to get rid of any airlock inside.

Circuit priming failure, blockage

In case the machine can't succesfully finish the self priming, You will get this message, meaning that there is probably a blockage in the machine.

Refill watertank

This machine lets you know when the water level is low in the tank.
Fill the water tank.

Switch the machine off then on again to solve the problem

This message can indicate three things and You can determine the most likely one by observing when the message comes on. It might be on a few seconds after turning the machine on, indicating that there is no change in the boiler temperature, meaning that the machine is not heating. However, if it comes on later as You press the coffee button, then the grinder is most likely blocked. In case it comes on after the grinding process and it won't start the coffee brewing process, then the brew unit is probably blocked.
Clean and lubricate brew unit.
Clean and readjust grinder.

Call customer service center

If You get this message, then it is pointless to call anyone, except a service agent for an appointment.

Add coffee beans, Coffee beans empty

If the message appears in the middle of the grinding process, and the ground coffee gets thrown into the dump box without the coffee being brewed, then the coffee container is either empty or the grinder blades are blocked by wet or greasy coffee.
Fill the coffee beans container.
Clean and readjust grinder.

Close the door

The machine indicates that the service door is not properly closed.
Make sure the service door is properly closed.

Close coffee container

This message indicates that the coffee container is open.
Close the coffee container lid.

Insert drip tray

The drip tray beneath the brew unit is not in place.
Make sure the drip tray is correctly in place.

Insert the brew unit

If You don't put the brew unit back with a firm movement, then it might not sit back correctly in place and as a result it would most likely not press the microswitch sensing its presence.
Make sure the brew unit is correctly in place.

Insert dreg drawer

The most common problem is spilled ground coffee behind the dump box, making it impossible to put it back.
Check the dump box, it might not be correctly in place.

Empty dreg drawer

The machine counts the number of coffees made since the last time the dump box was emptied and after about 13 coffees it will give the signal to empty it again. You also need to remember to empty the drip tray along with the dump box as well, because the tray has no separate sensor.
Empty the dump box.

Empty drip tray

This message appears in case the drip tray beneath the brew unit is full of excess water.
Empty the drip tray.

Insert the milk container

Without the milk container the machine can't dispense milk based beverages.
Put the milk container back into the coffee maker.

Replace the Aqua Prima filter, Replace water filter

In case You use the water softener cartridges instead of descaling the machine, then You need to replace it if this sign comes up.
Replace the water softener cartridge.

Descale the machine

The machine measures the amount of water that ran through the system since the last time the signal was resetted, and depending on the water hardness level settings, it will give the signal again after the pre-programmed amount of water ran through the system again.
Descale the machine.

In case You can't or don't want to resolve the problem with the tips above, then the machine needs the attention of a professional.

Water related issues

Leaking

Dirty water

This problem is mainly caused by ground coffee piling up in the drainage vent, blocking the path of the excess water let out by the overpressure or the boiler valve.

Lukewarm

Oddly enough in most cases this issue is not related to the machine at all. It is rather related to the cold mug or cup the user brews the coffee into.
Pre-heat the cup before brewing coffee.

Cold

This is a rare issue, mainly caused by a faulty temperature sensor.

In case You can't or don't want to resolve the problem with the tips above, then the machine needs the attention of a professional.

Coffee consistence

Weak

The strength of the coffee is influenced by the coffee blend, the ground coffee fineness and quantity, the temperature and the pressure. A weak coffee might be the result of stale beans or too high arabica percentage, coarse ground coffee, low ground coffee quantity, low temperature, or a combination of these.
Readjust the grinder to grind finer.
Set the ground coffee quantity higher.
Try different beans.

Strong or sour

The strength of the coffee is influenced by the coffee blend, the ground coffee fineness and quantity, the temperature and the pressure. A strong coffee might be the result of high robusta percentage, fine ground coffee, high ground coffee quantity, high temperature, or a combination of these.
Readjust the grinder to grind coarser.
Set the ground coffee quantity lower.
Try different beans.

There is no crema on top

In the world of automatic machines the theme crema will be somewhat simplified because of the low number of factors the user can influence and the low precision value of these adjustments. Basically there are three adjustable factors that have the most influence on the crema in a correctly operating automatic machine. These three factors are the coffee beans, the grinding fineness and the ground coffee quantity. The higher robusta percentage, the finer the ground coffee and the higher the coffee quantity is, the thicker the crema will turn out to be.
Readjust the grinder to grind finer.
Set the ground coffee quantity higher.
Try different beans.

In case You can't or don't want to resolve the problem with the tips above, then the machine needs the attention of a professional.

Milk froth consistence

Milk warms up, but is not froted

If You have steam pressure, but the milk is not frothed, then the problem can only be with the frother device. The most common problem is that the frother is not perfectly clean. You need to make sure to keep the small hole on the side of the frother attachment clear.
Clean the frother attachment and steam wand.
Descale the machine.
