Hello,
I have a problem with my dishwasher machine. It is a Whirlpool GU1108XTLB0.
The problem is that it works only the china crystal program. All other
programs do not work if I press the buttons and even the buttons lights
do not come on. Moreover, when I use the china crystal program, sometimes
it stop working before the program ends and the cancel and the program
lightes blinks. Sometimes it finish the program but after a while it
stars the program again.
Any clue?
Most likely the problem is a bad keypad assembly which is a part of the console, but there is a small chance for the control board to be bad as well. I would replace the console first. If you need the correct part number for the console, post the color of it.

You could improve your odds of getting the correct part by checking the keypad/console with a meter. If it checks out OK then it is more likely to be the control board that is the problem.
Here is the tech sheet with info on checking the keypad

You could also try the following though it is a long shot as sounds like you have a large number of keys that are not working.
Connector Cleaning / Checking
Unplug the unit
Open it up
Remove the ribbon cable from the keypad to the control board at the control board.
Clean the edge connector.
If it is the type where there is not a connector just the insulation is removed, it can be cleaned with a pencil eraser. Do not use an ink eraser as it is too abrasive.
Check the tracks in the ribbon cable for hairline cracks. A magnifying glass helps here.
Would not hurt to clean the connector on the board. Use electronics contact cleaner or isopropyl alcohol and a tooth brush. Be gentle and do not reconnect till all the solvent evaporates.
Reconnect everything and give it a try.
