Descaling light came up on my Bosch Tassimo machine for the first time since I purchased it.
Asked Mr Google about suitable tablets and he answered with these.
Found them on Amazon at a decent price, next day delivery with Prime membership and one 20 minute / easy to follow desclaing programme later, hey presto the machine is back producing gorgeous coffee once more.
And I've still got enough tablets left for 2 more descaling programmes, perfect!
Highly recommended product.
