Description

This is the main control board assembly that manages the appliance's user interface and operational functions, restoring control when the original board is faulty. It routes signals between buttons, sensors and motors so cycles run as commanded. What it does:

• Processes user inputs and controls cycle selection and timing
• Communicates with sensors and motors to start, stop and change cycles
• Powers and updates the display and control indicators
• Failsafe symptom indicators: unresponsive controls, blank or erratic display, failure to start or complete cycles, or persistent control-related error codes

What's included:

• One main control board

Install notes:

• Disconnect power (unplug or turn off breaker) before servicing to avoid shock
• Handle the board by its edges and avoid static discharge; use ESD precautions if available
• Verify all connectors match and seat fully; note harness positions before removal
