Tassimo troubleshooting

Updated February 21, 2017

Manufactured by Bosch home appliances, Tassimo is a home brewing system that makes individual servings of coffee, espresso, cappuccino and latte macchiatos, as well as tea and hot chocolate. This automated home brewing appliance reads the bar code of the beverage (called a T disc) you place in the system and adjusts its settings to brew the drink you want. If your Tassimo brewing system stops working properly, try a little troubleshooting yourself before sending the unit out for repairs.

Put a T Disc onto the disc holder if you find that the Tassimo is unable to move past the "Standby" mode. Press firmly on the top of the brewing mechanism to ensure its closure.

Replace the cup you have been using with a bigger cup if you have issues with overflowing drinks. Use a 340gr. cup for coffee, cappuccino, latte, hot chocolate and tea. Use a 85.1gr. cup for espresso.

Move the cup stand lower to accommodate a larger sized cup by putting your finger into the centre of the stand and turning it clockwise. If your cup size still exceeds the space available, remove the entire cup stand and drip tray to fit your cup.

Elevate the cup stand by lifting the middle of the stand with your finger and turning the stand counterclockwise. By elevating the cup stand, you are bringing your cup closer to the brew mechanism, inhibiting and avoiding splashing while the beverage is brewing.

Turn the machine off if the indicator lights flash for longer than a couple of seconds. To prepare the coffee machine, fill the water pot to the maximum level then put it back into the appropriate compartment found on the back of the Tassimo machine.

Turn the Tassimo machine on and put a 340gr. cup on the cup stand. Put a cleaning disc with the bar code facedown on the T Disc holder through the top opening of the brew machine. Press the clamp down over the cleaning disc until it closes all the way.

Press the "Start/Stop" button. When the "Standby" light turns on, you must open and close the brew mechanism. Watch while the heating light goes on, then the green coloured "Auto" light will turn on. Now press the "Start/Stop" button once more and then take out the cup, discard the contents and return it to the cup stand.

Take the cleaning disc out of the brewing mechanism and put a T Disc into the brewing machine with the label side facing downward. Once the heating light turns on, begin the brewing process.

Clean the window of the bar-code reader located above the piercing unit, as the problem may be that the system is unable to read the bar-codes. Use another T Disc if this approach is ineffective.

Stop the brewing cycle by pressing the "Start/Stop" button if the brewing machine is leaking. Open the top of the brewing machine and take out the T Disc. With a soft cloth, clean the machine by thoroughly wiping the interior.

Remove the piercing unit by pulling it out and replacing it with another one. Press down on the replacement piercing unit to ensure it is in place.

Turn off the Tassimo and unplug it. Remove the cup stand, the drip tray and the back splash from the brewing machine. Reassemble the parts you removed, be sure to securely reposition them to ensure functionality.

Clean the water-expansion outlet located directly above the cup holder using white vinegar or lemon juice applied with a soft cloth.
