Dishwasher displays E10; control panel is responsive but cycle will not start or advance.

Safety first: Disconnect power before accessing control electronics.

• Perform a hard reset: Turn off the breaker for 5–10 minutes, then restore power and attempt to start a cycle. Sometimes this clears transient faults.
• Inspect control board connections: Remove the inner door panel to access the main control board. Check all harness connectors for secure fit and signs of corrosion or heat damage.
• Check user interface ribbon cable: Ensure the flat ribbon cable between the touch panel and control board is fully seated and not damaged.
• Look for burned components: Visually inspect the control board for burned spots, swollen capacitors, or damaged traces. If present, the board should be replaced.
• Replace control board if necessary: If wiring and UI are good but E10 persists, install a new OEM control board, transferring any jumpers or configuration plugs as per service instructions.
