⚡ TL;DR — Quick Answer

Dry the control panel, do a power reset, and check for stuck buttons; if nothing helps, the panel or board needs replacing.

Understanding Not Responding Buttons

The control panel is a membrane keypad wired to the main board. Sticky residue, moisture, or a worn contact makes buttons unresponsive. Sometimes the machine simply needs a reset to clear a frozen control state.

Universal Troubleshooting Steps

These steps work across all major brands:

  1. Wipe the panel with a dry cloth and check that no button is physically stuck.
  2. Unplug the machine for 60 seconds, then plug it back in and test.
  3. Clean around the buttons with a barely damp cloth; avoid moisture getting under the panel.
  4. If only one button fails, the keypad may need replacement; if all fail, check the control board.
