Dishwasher displays E10 and may not start or may stop unexpectedly; control panel may be unresponsive or erratic.

Safety first: Disconnect power at the breaker before removing any control panels.

• Power reset: Turn off the breaker for 5 minutes, then restore power. Sometimes a control lockup can be cleared with a hard reset.
• Check for moisture: Remove the inner door panel and inspect the UI board and wiring for signs of moisture or corrosion from steam leaks. Dry gently and correct any gasket issues.
• Inspect wiring harness: Verify that the ribbon cable or harness between the UI and main control board is fully seated and undamaged.
• Look for board damage: Examine both boards for burned components, cracked solder joints, or discoloration. If found, replacement of the affected Dacor control board is recommended.
• Professional service: Because control electronics are expensive and require correct programming, consider having a Dacor-authorized technician confirm the diagnosis before replacing boards.
