I found the use of these pellets very easy: just put 500 ml of water in the tank (right half), dip 2 tablets, they are conditioned by two, that's good! insert the orange plastic cap provided when purchasing the Tassimo Joy, and press and hold the button that usually serves to launch the programming of a drink, Useless, as has been said above of having to buy a yellow plastic capsule, the original one for cleaning is also provided for descaling, the device distinguishes depending on the length of pressure is exerted on the start button. Small particles can be observed in the water discharged by the machine, the tartar ... The cycle lasts about 20 minutes. You have to flush the tank to remove residues of pellets, fill it thoroughly with 1 liter of water, then run 4 sets of cleaning, and now it's over! The machine gives new tasty drinks at the right temperature, it's magic!
