Electricity related issues

Not turning on

Cable and cable fuse

It is really rare for the fuse to go, but can happen in case of a shorted component.
Check the fuse in the plug. Make sure the plug is properly connected into the connector slot.

Door microswitch

In these models the door microswitch is located on a separate stand which can flip out of it's place.
Make sure the service door is properly closed and the flap pressing the door microswitch is not deformed.

Inner fuse

In case of a power surge in the house the inner fuse is the most likely part to go.

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.

Electric panel

Mainly the transformer is the part that causes this symptom.

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.

Normally this is the sign of the machine heating and it should switch to steady after maximum 5 minutes.

Green steady on

The machine is ready for use in the selected mode (coffee or steam).

Green fast flashing

This mainly occurs after steaming with the machine, because the boiler needs to be cooled down to coffee temperature.
Let water through the steam wand to cool the machine down.

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.

In extreme cases, the lack of lubrication can even lead to overexerting and damaging the gearbox.

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.

Slow brew unit operation

Brew unit clogged up

The fault might simply originate from the lack of maintenance, caused by piled up ground coffee blocking the operation of the brew unit.

End product related issues

Coffee dripping

Brew unit clogged up

A possible problem is that the shower disc is blocked by coffee residue.
Clean and lubricate brew unit.

The ground coffee is too fine

The grinder fineness settings might be too fine and water can't pass through the ground coffee, or the ground coffee is so fine, that it can block the shower disc.
Readjust the grinder to grind coarser.
Set the ground coffee quantity lower.

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.

Readjust the grinder to grind finer.
Set the ground coffee quantity higher.

Wrong beans

The beans might be stale or the percentage of arabica beans in the blend might be too high. For these machines we reccomend at least 40% robusta percentage.
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.

Coffee temperature

Too high

The temperature might be too high in case the system has a larger amount of limescale built up inside.
Descale the machine.

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.

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.
