Washer displays E47 and will not start or complete spin cycle.

Safety First: Unplug the washer before accessing any control boards.

• Power cycle: Unplug for 10 minutes to discharge capacitors, then plug back in and try a spin-only cycle.
• Inspect wiring: Remove the rear or top panel to access the main control and motor control (if separate). Check the multi-pin connectors between boards for secure fit and signs of corrosion or burning.
• Check for moisture: Look for signs of water leaks that may have dripped onto the control boards. Address any leaks before replacing electronics.
• Visual inspection of boards: With power disconnected, inspect for burned components, bulging capacitors, or cracked solder joints.
• Replace suspect board: If the motor control board shows damage or if GE diagnostics point to inverter failure, replace it with the correct GE part. If the inverter looks good but communication remains faulty, the main control board may need replacement.

Note: Board-level diagnosis often requires GE service mode and specialized tools; consider a professional if unsure.
