In most cases, a coffee maker can be repaired by its owner even if he doesn’t have any previous experience in this field. However, the simplicity of coffee makers can be deceptive. You definitely need a reliable guide to make the troubleshooting easy, effective, and safe for both you and the device. The tables below include advice on solving all the common issues.
How to use bosch coffee machine
Brewing a cup of coffee in a Tassimo coffee machine is pretty much the same as doing so in any similar coffee maker. All Tassimo modifications share common features, particularly T discs.
- Check the water reservoir and pour in water (if it is empty or near empty).
- Put a cup or mug on the holder in the front part of the unit. Be sure it is big enough to handle the needed amount of the drink (an espresso cup will be too small for a full cup cycle).
- Press Power and wait until the standby light comes on.
- Open the lid and insert a T disc with the beverage type you want to brew. Make sure the barcode is facing down and the tab of the disc matches the slot on the right side. To close the lid, press it all the way down (you should hear a click).
- Wait until the standby light comes on. Now the coffee maker is reading the barcode. The green light coming on will mean that the machine is ready to start brewing.
- Press “Start/Stop” to start the cycle. Once the right amount of liquid is released, the brewing process will stop. If you want a smaller drink, you can press the button around the middle of the brewing process.
- When the orange standby light comes on, remove the T disc. To be on the safe side, prepare an oven mitt, because the disc may be hot right after use.
- You can brew another drink right after a previous one is finished providing that you use a fresh T disc and another cup. If you are not planning brew any more drinks, turn off your coffee machine.

How to clean a Tassimo coffee machine
Tassimo coffee machines are very user-friendly and do not require complicated maintenance. However, they do need proper and regular cleaning and descaling. Failure to do so can pretty much spoil the taste of coffee or cause a blockage in the system. The procedure consists of a few steps:
Step 1
Take off all removable parts of your coffee machine and rinse them in running hot water with dish soap. Make sure you do it thoroughly. When you are through with the rinsing, put the part in a dish drainer and let them air-dry by themselves.
Step 2
Each machine comes with a reusable cleaning disc, which you can find in the brewing unit. Use it at least once a week. When inserting it, please, be sure that the bar code is facing downward. The disc is also great for descaling the device.
Step 3
Fill the water reservoir with cold water and run a usual cycle. You a kind of use the cleaning disc instead of coffee grinds.
Step 4
When the cycle is over, remove the cleaning disc. Put it somewhere, so that you can find and use it after another week. Turn it off and take the cup of water out of the machine (it should have come out during the cycle). Rinse the cup in warm water with dish soap.
Step 5
Soak a little rag in a water/vinegar solution (50/50) and wipe your Tassimo machine’s body. Thus you will give your unit a bit of good looks plus disinfect the surface.
