Dishwasher shows E10; unit may not start or may stop unexpectedly, sometimes after a power surge or outage.

Safety first: Disconnect power before accessing the control area.

• Power reset: Turn off the circuit breaker for 5–10 minutes, then restore power to see if the error clears.
• Inspect wiring: Remove the inner door panel and check all connectors to the main control board and user interface board. Reseat any loose plugs.
• Check for surge damage: Look for burn marks or swollen components on the control board. If present, the board must be replaced.
• Replace control board: If E10 persists after a reset and connections are secure, install a new main control module programmed for your specific Summit dishwasher model.
• Use surge protection: Consider using a surge protector on the dishwasher circuit to prevent future memory corruption from voltage spikes.
