Question 1

Do I need to insert a new filter after cleaning or can I reuse the old one?

Accepted Answer

The filters should be replaced every few months as they have a limited lifespan. If you descale your machine regularly, a water filter is often not necessary. Many users even manage without one altogether.

Question 2

Should the sieve also be cleaned if coffee oil remover tablets are used regularly?

Accepted Answer

Yes, it is recommended to clean the sieve manually occasionally. Simply open it and check that it is clean. If you regularly use cleaning tablets, it may be necessary less often.

Question 3

Can I put a cleaning tablet or a degreasing tablet in the water tank?

Accepted Answer

No, this is not recommended. Grease collects mainly in the brewing unit and the coffee outlet. Use specially developed cleaning tablets for this. You should only clean the water tank with suitable descaling agents.

Question 4

Can I clean the brewing group or parts of the coffee machine in the dishwasher?

Accepted Answer

Yes, but only with caution:
 • Place the items in the dishwasher for 30-40 minutes and pause the program before the hot phase. The high heat can damage the material and make the plastic porous.
 • After cleaning, the seals should be re-greased.
 • Painted parts do not belong in the dishwasher.
Note: Dishwashing detergent is usually only added during the hot phase, so the parts will not be affected if you remove them beforehand.

Question 5

How can I prevent mold in the machine?

Accepted Answer

Leave the drip tray open after each use so that the machine is well ventilated and residual moisture can escape. Otherwise, mold can form, which can be harmful to health.

Question 6

What to do if the coffee machine trips the residual current device?

Accepted Answer

A short circuit caused by a leak inside the machine is likely. Possible causes:
 • Defective pipe on the boiler
 • Problems with the Raccord valve

Open the machine and check these components. There are numerous helpful videos online that demonstrate the repair process.

Question 7

Gas fuse blows or the residual current device trips. What to do?

Accepted Answer

• Check whether water has gotten into the electronics.
 • If not, disconnect the 220V consumers such as boiler, water pump, grinder and heating plate one by one.
 • Switch the machine on and reconnect the consumers one by one. As soon as the fuse trips again, you have identified the faulty consumer.
Caution: Always disconnect the machine from the power supply before connecting or removing components.

Question 8

Why do I find water under my machine in the morning?

Accepted Answer

Water leaks overnight indicate a leak between the water tank and the water pump.
Solution:
 • Remove the covers from the machine to get a better view of the connection points.
 • Check and replace seals if necessary.

Question 9

Why does water collect in the drip tray when the machine is turned off?

Accepted Answer

The water pump may be leaking slightly when not in use, allowing water to flow from the tank into the drip tray. Check the pump and replace any leaking parts.

Question 10

Why are the coffee grounds mushy, moist or crumbling?

Accepted Answer

This problem can have several causes:

1. Leaking brewing group: Perform a test without the drip tray to check the leaks of the brewing group during brewing.
2. Coffee grinding level too coarse: Even if the knob is set to "fine", the grinder can be readjusted.
    • Remove the top cover of the machine.
    • Manually adjust the grinder to a finer setting.

Question 11

How much water in the collection container is normal?

Accepted Answer

After each coffee brewing, residual water flows from the brewing group into the drip tray. As long as no water is lost during the brewing process, the amount in the drip tray is normal.

Question 12

Coffee machine shows "No water in the tank" even though the tank is full.

Accepted Answer

Possible causes:
 • The water tank sensor is defective or the plug is wet.
 • The magnetic float in the tank may be stuck or rusted.

Question 13

How do I set the finest setting after cleaning the grinder?

Accepted Answer

• Turn the cleaned grinder completely until it stops moving.
 • Then open it by 4-6 teeth . This corresponds to the finest setting.

Question 14

How many ohms should the boiler heating element have?

Accepted Answer

• The resistance of the heating element should be between 30 and 45 ohms .
 • An increase in resistance between the metal of the boiler and the heating element indicates a defect and can trigger the residual current device.

Question 15

Accepted Answer

Cause:
 • Clumped coffee due to water in the grinder.
 • Incorrectly connected grinder motor.
 • Grinder set too finely.

Solution:
 • Clean the grinder thoroughly.
