Frequently Asked Questions - 28815 UNOLD

How to adjust the grind fineness?
Open the bean container and turn the adjustment knob (positions 0 to 12) during grinding. A lower position gives a finer grind, ideal for intense aroma. Adjustment must be done only when the grinder is running.
What to do if the message 'Fill water tank' appears even though the tank is full?
Shake the tank gently to free the float. If the problem persists, remove the tank and reinsert it correctly into its housing.
How to descale the machine automatically?
Use a suitable descaling agent. Put the mixture in the water tank, place a container under the steam nozzle, open the steam regulator and start the program via the menu (press MENU until you see 'ENTKALKEN STARTEN'). The cycle lasts about 30 minutes. Follow the on-screen instructions.
How to clean the brewing unit?
Turn off and unplug the appliance. Open the side cover, remove first the grounds drawer then the brewing unit. Clean it under running water without detergent, use the provided key to rotate the shafts. Lubricate the red seal and slides with silicone grease. Reinsert the unit until it clicks.
How to adjust the water amount per cup?
In 'BETRIEBSBEREIT' mode, select the desired cup size. During extraction, hold down the button until the desired amount (40-80 ml for small, 100-150 ml for medium, 150-300 ml for large). Release to save.
What to do in case of message 'Electronic failure'?
Turn off the appliance immediately and contact customer service. Do not attempt to repair yourself.
How to use the steam nozzle to froth milk?
Make sure the screen shows 'BETRIEBSBEREIT'. Press MENU to heat, wait for 'DAMPF BEREIT'. Immerse the nozzle in the milk, open the steam regulator, froth, then close the regulator. Beware of burns.
How to enable or disable pre-grinding?
In the menu, access the submenu 'VORMAHLEN' (press MENU 3 times). Use the selection button to switch from 'AUS' to 'EIN'. Confirm by holding MENU.
Why doesn't coffee flow or flows slowly?
This may be due to a need for descaling or a clogged grinder. Perform manual or automatic descaling. Also check that the grind is not too fine.
How to reset to factory settings?
In the menu, access the submenu 'WERKSEINSTELLUNG' (press MENU 7 times). Hold MENU for 3 seconds to restore default settings.

BASIC SETTINGSFOR THE PREPARATION OF COFFEE

Water quantity per cup

According to general standards, the default setting corresponds to the following quantities:

UNOLD 28815 - Water quantity per cup - 1

40 ml (adjustable from approx. 40-80 ml)

UNOLD 28815 - Water quantity per cup - 2

120 ml (adjustable from approx. 100-150 ml)

UNOLD 28815 - Water quantity per cup - 3

200 ml (adjustable from approx. 150-300 ml)

Nevertheless, the quantity of water per cup can be adjusted to your needs within the limits indicated above. Please proceed as follows:

Make sure that the display indicates

BETRIEBSBEREIT

(READY). Then press the button corresponding to the desired cup size and maintain this button pressed. As soon as the desired level is achieved, release the button. The automatic coffee machine stops the brewing process and saves the brewed quantity as standard for the corresponding cup size. The next time you brew coffee with the corresponding button, the saved quantity of coffee will be brewed.

ATTENTION:

Please use a measuring cup when adjusting the water quantity. If the button is still pressed when the minimum or maximum quantity for the respective cup size is reached, the appliance returns to the default settings without saving the new settings.

The settings can be adjusted for all three cup sizes correspondingly.

The capacity per cup can be saved within the limits indicated above. If the respective lower or upper limit is exceeded, the automatic coffee machine activates the corresponding minimum or maximum capacity.

Quantity of coffee powder per cup

The default setting is of 7 to 8g ground coffee per cup. If you desire to change this quantity, please open the lateral cover of the automatic coffee machine.

Push the red lever above the brewer assembly towards - to reduce the quantity and obtain a weaker coffee or towards + to increase

the quantity and obtain a stronger coffee. Adjustments can be made between 6 and 9g

ATTENTION:

In order to increase the service life of the appliance, we recommend not to adjust the appliance permanently to the maximum coffee powder quantity.

Degree of grinding

The default setting corresponds to a medium degree of grinding. The degree of grinding may be also adjusted as you require. For this purpose, open the coffee beans container and turn the knob to set the degree of grinding (0 = very fine to 12 = coarse).

The ner the grind, the more intense the aroma of your coffee.

CAUTION:

The setting must be adjusted while the grinder is in operation. Do not change the setting when the grinder is not operating in order to prevent the grinder from being damaged.

As there may be some ground coffee left in the grinder from previous use, the adjustment may not make a difference until the second or third cup. If necessary, you may correct the setting accordingly.

In order to increase the service life of the appliance, we recommend not to adjust the degree of grinding permanently to the nest grind.

ATTENTION:

If the pre-grind feature is selected, there will be always a certain amount of coffee powder in the coffee powder chamber. This might block the red lever when trying to adjust the quantity in one step. To avoid this, we recommend to deactivate the pre-grinding feature temporarily or adjust the quantity in several steps.

Pre-grinding

Usually the coffee beans are ground immediately before brewing the coffee.

When pre-grinding is selected, immediately after brewing a cup of coffee the coffee powder for the next cup is ground, so that this step is omitted in the brewing. Thus, the preparation time for a coffee is slightly shorter. The activation of pre-grinding is recommended when using the appliance frequently.

To activate the menu, press the MENU/MENU button until the message on the display changes.

Press the MENU/MENU button three times. The display indicates:

VORMAHLEN AUS

To activate or deactivate pre-grinding, please press the button
