bosch sl15j1b dishwasher won't end a cycle?

Hi, Our Bosch dishwasher won't end any cycle and doesn't seem to get hot either. I looked on the bosch website and it says to run a test cycle, and when I do it flashes the 35 degree light and the 50 degree stays on, this is supposed to tell me what is wrong but I can't see this description on their site. Can anyone help?
Best regards
Spencer.
