Question 1

How to memorize coffee doses with buttons A, B, C, D on the RANCILIO Classe 6?

Accepted Answer

Memorizing coffee doses with buttons A, B, C, D is available exclusively on the electronic model (E) of the RANCILIO Classe 6. The semi-automatic (S) and mechanical lever (L) models do not have this feature.

Procedure for memorizing a coffee dose:

Press and hold the E button for 8 to 10 seconds until the corresponding LED on the left keypad starts blinking rapidly (programming mode activated).
Place the portafilter with freshly ground coffee under the group.
Press the desired button: A, B, C, or D according to the desired cup size (the coffee starts to flow).
Once the desired amount is obtained, press the same button again to stop the flow. The microprocessor automatically memorizes this dose.
To program other doses (if necessary), repeat steps 2 to 4 with each button (A, B, C, or D), using a new portafilter and freshly ground coffee each time.
Once all doses are programmed, press the E button again to exit programming mode (the LED turns off).
Check the programming by preparing coffees and controlling the quantities in the cup.

Memorizing hot water doses:

The same procedure applies for the 5B buttons (dosed hot water). Hold the E button for 8 to 10 seconds until the LED blinks, place a container under the spout, press 5B to start, then press 5B again once the desired amount is reached. Press E to validate and exit programming.

Important: This function is only available on electronic models (E). Make sure to use freshly ground coffee for each dose and check the quantities after programming for optimal results.

Question 2

How to measure quantities in ml in a glass with the RANCILIO Classe 6?

Accepted Answer

The RANCILIO Classe 6 does not include graduations in ml in its manual or on the measuring cup. However, the machine specifies a standard dosage of 6 grams of coffee per dose, with an optimal extraction time of 25 to 30 seconds.

To measure quantities in ml of water or brewed coffee, we recommend using:

A measuring cup - The most practical and economical way. A standard kitchen cup of 250 ml is equivalent to one cup of coffee.
A kitchen syringe - Ideal for measuring small quantities accurately if you need very specific doses.
A digital scale - Measures ground coffee by weight (approximately 0.55 g per ml).

The machine is designed to optimize dosage by extraction time (25-30 seconds) rather than by volume in ml, ensuring higher quality espresso.

Question 3

How to turn off the RANCILIO Classe 10 coffee machine?

Accepted Answer

To turn off the RANCILIO Classe 10 coffee machine, you need to deactivate the main switch, identified by number 1 and located on the front panel of the machine. This switch is a two-position selector equipped with a light indicator.

The operation is simple: toggle this switch to the OFF position (down position). The light indicator will turn off immediately, signaling that the main power is cut off and the machine is completely stopped. No electrical power reaches the components of the machine.

Important: do not confuse the main switch (number 1) with the boiler heating switch (number 2), which only controls the heating of the water in the boiler. This switch alone does not stop the machine or the operation of the pump.

For a complete and safe shutdown: first, you may optionally deactivate the boiler heating switch (number 2) if you no longer wish to heat the water, then toggle the main switch (number 1) to OFF. The machine will be completely powered off.

If you need to perform maintenance or stop the machine for an extended period, you can also turn off the external power supply valve (circuit breaker) that supplies the machine, in addition to deactivating the main switch.
