Clean and descale your tassimo

  1. Fill water tank and add 2 TASSIMO descaling tablets. Make sure the tablets are fully dispersed.

  7. Rinse and clean the water tank to remove any traces of descaling solution. Refill the water tank with cool fresh water, up to the max mark and place it back in your machine.

  8. Press the Start/Stop button briefly to run the cleaning cycle. When the cleaning process is complete, empty the container and place it back. Repeat the cleaning process (refill tank and run cycle) 3 - 4 times to ensure all the descaling solution is flushed from the machine.

Why should you clean and descale your TASSIMO machine?

Descaling your machine will keep it in top condition, so that it can continue to make your favourite, high quality beverages. All coffee machines are susceptible to limescale build-up, which might damage them. The descaling cycle will remove any limescale, residue and calcium deposits. Descaling your machine is essential to increase the life of your machine and to get the best quality drinks from the machine. The machine will let you know when it needs a descale by illuminating the red descale indicator light.

When should you descale your TASSIMO?

As soon as the red light is on, descaling your Bosch TASSIMO coffee machine is required. You need to descale your TASSIMO machine approximately 4 times per year. It takes about 30 minutes to fully clean an descale your machine.

The descaling indicator light is, for the most TASSIMO machines, the bottom light. It’s either a spray icon or it says ‘calc’. Please start the descaling programme as soon as possible when the red light is on, or when it starts flashing.

How to use TASSIMO descaling tablets?

Descaling your TASSIMO is effortless and effective when you use products that are designed for your TASSIMO coffee machine. TASSIMO recommends to only use the official TASSIMO by Bosch descaling tablets. Never use vinegar or acetic acid-based descalers, these can harm your machine and the taste of your drinks. To descale, take two of the tablets and dissolve in water in the water tank. Please follow the steps above.
