Dishwasher will not start; control panel lights may be frozen or unresponsive; sometimes beeps and then shuts off.

Safety First: Unplug the dishwasher or switch off the circuit breaker before working on any electrical components.

This code on Whirlpool dishwashers typically indicates a problem with the main control board.

• Power reset: Turn off power at the breaker for 5 minutes, then restore power and try to start a cycle. This can clear a temporary logic fault.
• Check for moisture or corrosion: Remove the toe-kick panel, locate the control board housing (usually in a plastic box at the bottom right), and inspect for signs of water intrusion or burnt components. If you see burn marks or melted spots, the board must be replaced.
• Inspect wiring harness: With power still off, remove the control board cover and gently tug each connector to ensure it is fully seated. Look for discolored or loose pins.
• Keypad test: If the control panel buttons are stuck or unresponsive, disconnect the keypad ribbon cable from the control board (if accessible) and see if the error changes or clears after restoring power. A shorted keypad can trigger this code.
• Replace the control board if needed: If the error returns immediately after reset and wiring is intact, the main control board is likely defective and should be replaced with the correct Whirlpool OEM part number for your model.

If you are not comfortable working with live wiring or control electronics, contact a qualified technician.
