So every button, other than Start does, responds and works fine?
Check responsiveness of each key.
If some keys do not respond:
- Unplug dishwasher or disconnect power.
- Disassemble door and inspect for correct assembly of control, console, and button tree.
- Adjust assembly to eliminate stuck keys, reassemble door and test each key.
- If key(s) still stuck/ unresponsive, replace control board.
