Candy CDI 454 doesnt work – only testprogram respond

When switch power on my dishwasher CDI 454 doesnt respond anymore. Number 15 or 14 is shown in the display but I can’t select or start any program. No respons with the program or countdown button.

When I turn on power with pushing the countdown button all lights are flashing. When I push the program button some testprogram is starting at number 18.

18 start
17 hear water coming in the dishwasher
16 wash program start
15 a break
14 wash program start again
13/12 break
11 pump the water out of the dishwasher

After this short test program there is a beep and b0 or 60 is displayed. The dishwasher is not responding when pushing the program or countdown button again.

When switch power off/on there is number 15 or 14 again in the display. No respons with the buttons.

Does anyone know whats wrong with my dishwasher?
