I have A Bosch dishwasher which was making a strange noise the last time it ran about two days ago. Now it won't run at all and I get the code 2H for all of the cycles except for rinse hold which counts from 10 to 0, although nothing happens while it is counting.

Is it possible to tell what is wrong from the 2H code? I did try to reset by holding down two buttons and pressing start. The dishwasher LED went to 27, then back to 2H and still is not running.

Thanks in advance for your assistance
