I have two flashing red lights on my tassimo. Nothing I have tried works.

I had the same problem with my machine and managed to get it working again in a few easy steps. This machine is great but it can be VERY tempermental so here are a few tips:
1.The barcode reader MUST be clean or it will not read what the disc is (It is the little glass screen where you place the disk.) If it is not clean the lights will all flash.
2. The little floaty thing in the water container has to be floating in order to keep the machine running- if it won't float, shake it well to dislodge the air pocket that might be jambing it.
3. If the red stanby light won't go away, it is because the disc you are using is either damaged or leaking and it WON'T go away until you replace the disc...(you might have to do it more then once) if that doesn't work- try hitting the reset button on the back of the machine (the little black switch that has a (- and o) as well as unplugging and plugging the machine back in. Lastly, what worked for me was inserting a new disk and only partially clicking in the disk so the 'heating' light came on- leave it like that for about 10 seconds and then very slowly close the disc completely. Hope this helped!
