A little bird tells me that on the newer Bosch dishwashers, not sure what models that they will often throw up an E19 error.
This will usually mean a blown main PCB.
Advice is, do not change just the board as the dump valve as it was called in the base and/or the dispenser being shorted or faulty can and does bow the board.
So, if you don’t replace all three you can put a new board in and pop that soon as you power it up. An expensive mistake.
Thought it was a handy tip you all might like to know about.
