- If nothing happens, try quick variations noted for your model (some use Start then hold options).
Reset control logic / clear lock or delay states
- Check if control lock or delay start is active (icons on panel) and hold appropriate buttons to cancel.
- Perform a control panel reset by holding the Start/Cancel button for 3–5 seconds.
- If still unresponsive, power off via breaker or unplug for ~5 minutes to reset logic.

Next step
Choose the next step for not entering diagnostic mode
Confirm the diagnosis before ordering. An error code can identify the system involved, but it does not prove that a specific part has failed.
Browse by model — no specific failed part is claimed
Model-compatible Dishwasher parts
Enter the complete model number to browse compatible replacement parts. This is a model-based parts search, not a diagnosis that a specific component failed.
Where can I find the model number?
Check the rating label around the door, lid, frame, rear panel, or inside the appliance cabinet. Use the complete model number, including suffixes.
Search results are not a diagnosis. Verify both the complete appliance model and the retailer's fit information before ordering.
