Washer-dryer combo displays E3 and stops during wash or spin; drum may not rotate or rotates erratically.

Safety first: Unplug the appliance before removing any panels. Do not bypass safety interlocks.

• Reduce load: Remove some laundry and try a smaller test load. Overloading can trigger E3 by stalling the motor.
• Check for drum obstruction: Spin the drum by hand. It should rotate smoothly. If it binds or grinds, inspect for trapped items between the drum and tub.
• Inspect drive belt: Remove the rear panel to access the drive system. Verify the belt is on both the motor pulley and drum pulley. Replace if cracked, frayed, or stretched.
• Check motor capacitor (if equipped): Some Costway combos use a start/run capacitor mounted near the motor. Look for bulging, leaking, or burnt terminals. Replace if damaged.
• Inspect motor wiring: Ensure all connectors to the motor are fully seated and free of corrosion or burn marks.
• Advanced testing: Use a multimeter to check motor windings for continuity and proper resistance. If windings are open or shorted, replace the drive motor.
• If E3 persists after belt and load checks: Replace the motor or capacitor as indicated by testing. If the motor tests good, the motor control circuit on the main PCB may be defective and require professional replacement.
