Frequently Asked Questions - TKA6M273 BOSCH

How to set the water hardness on the Bosch TKA6M273 coffee maker?

Press and hold the Aroma and Descaling buttons for at least 3 seconds. The last setting flashes. Press the On/Off button within 7 seconds to select the desired setting: soft, medium or hard. The appliance automatically saves after 7 seconds of inactivity.

How to activate the Aroma intensity function?

Press the Aroma button within one minute after starting the brewing process. The symbol lights up white and the program remains activated for subsequent cycles. To deactivate, press the button again.

How to set the auto shut-off duration?

With the coffee maker turned off, press and hold the On/Off button for at least 3 seconds. The last setting flashes. Press the On/Off button within 7 seconds to choose between 20, 40 or 60 minutes. The setting is saved automatically after 7 seconds.

How to descale the Bosch TKA6M273 coffee maker?

Use a commercial descaling product (without phosphoric acid). Follow the steps: fill the tank with water and descaling solution, turn on the appliance, wait for the cycle to finish, empty and rinse several times. The descaling indicator flashes to indicate that descaling is needed.

Can I use vinegar for the first cleaning?

Yes, for the first cleaning, use a mixture of 5 cups of water and 1 cup of vinegar. Then perform two rinses with fresh water (6 cups each). Let the appliance cool down for 5 minutes between rinses.

What to do if the coffee does not flow or flows slowly?

This may indicate that the appliance needs descaling. Also check that the water tank is filled, the filter is not clogged, and the carafe is correctly positioned. If the problem persists, descale the appliance.

Can I use milk or instant drinks in the tank?

No, use only fresh, non-carbonated water. Milk, prepared drinks or instant products can damage the appliance.

How to clean the thermal carafe?

Rinse it with hot water. For stubborn deposits, use a solution of baking soda, dishwasher granules, or denture cleaning tablets. Never put the thermal carafe in the dishwasher or microwave.

Why is the On/Off button flashing?

Flashing can indicate different things: if the button flashes alone, the appliance is in standby or in auto shut-off mode. If it flashes together with the keep warm button, descaling is necessary. Refer to the manual for more details.

How many cups of coffee can be prepared at most?

The coffee maker can prepare up to 8 cups of coffee (approx. 125 ml per cup). The water tank has a maximum mark that should not be exceeded.
