Unfortunately you have to but if you use the Hot Water T-disc, remove the T-Disc punching device including nozzle from the machine - ie the silver nozzle otherwise in the open cup is inside. Because the Hot Water T-disc has its own nozzle! Made of plastic! At the bottom! (Which is not visible on the product image). Well stupid, because in everyday life makes the constant back and hertauschen between nozzle and Hot Water Disc no sense, because no one who wants a simple coffee, first Rumbaut on the machine.
This Hot Water T-Disc brings only a little, if one uses it once and then not take out again. But in parallel for use with ordinary Tassimo T-Discs, it is completely useless.
For comparison: When I insert the cleaning T-Disc into the machine, I have to rebuild the nozzle not only! And it comes just as hot water through - even if only 50ml. But I can hold the round button to let through more water, or I'll do the lid on and let + 150ml again in the cup, which then are just 300ml.
Long story short: I prefer to use the T-cleaning disc continues. Its use is much simpler and more practical for everyday use for 1 cup of hot water.
