MODEL-SPECIFIC QUICK ANSWER
Bosch TASSIMO HAPPY blinking lights and common signals
HAPPY TAS100x has a Start/Stop button, a status display, Fill water R, and Descale Q. The manual says a red status display when brewing will not start can mean no T DISC or an unread barcode. R is the water-tank indicator; Q means descale, and flashing Q means descale urgently. R and Q together with no brew indicate a machine fault.
