With the panel lit up, a failure to start usually means you need to check the selected setting and the start conditions. It does not prove that the control board is damaged.
Check the command it received
- Confirm that you selected a cycle and pressed start as the manual instructs. Some controls require you to hold or confirm a specific command.
- Check the delayed start or end. The time shown may indicate a scheduled wait.
- See whether the child lock is active; do not try combinations from other brands.
- Watch the door or lid lock indicator. Latching the catch does not guarantee it is recognized.
- Check whether it tries to drain or fill without getting water before moving on.
If the button does not register the command
Distinguish an acknowledgment sound or a visible change from a constant lack of response. If a button fails or the selector shows a different position, continue with unresponsive controls.
Do not press repeatedly or hit the panel. A command that arrives late can be mistaken for a lockup while the unit is still processing an expected state.
When the power state changes
If all indicators go out, stop treating it as a start condition and check power loss. If it stays lit with a message, keep the full text before canceling.
Note what changes right after you press start: lock, sound, display, and water intake help pinpoint where it stops.
