Bosch Dishwasher with E19 error code means there is an issue with the control board. If it is a new dishwasher, call the company you purchased from and let them know.
If you will have to repair yourself, a control board can be found online for around 100 US dollars.

Bosch Manual says = Seek technician if displayed.
Have you tried to reset the dishwasher by unplugging it from power for 10 minutes?
When the E19 error code is displayed, what exactly happens?
Does the dishwasher run at all?
At what point in the wash cycle did the E19 appear?
I have the same issue with error code E19. I could say that reset power for a couple of days did not help at all. This code shows in 2-3 seconds after dishwasher turned on, and then it do not react to any buttons. With my unit it appears during night wash. Machine stops with dirty water and highlighting “Need salt”. Salt addition did not help also. It s a Bosch Dishwasher SPS53M22EU.
