Washer-dryer intermittently stops mid-cycle without draining or spinning; no error code.

Safety first: Unplug the appliance before inspecting wiring or controls.

Step-by-step checks:

• Check power connection: Ensure the plug fits firmly in the socket and the cable is not being pulled or flexed excessively.
• Door lock: Wiggle the door gently during operation (with caution). If the machine stops, the door lock contacts may be intermittent and should be replaced.
• Inspect wiring: Remove the top cover and check harness connectors at the PCB and major components. Reseat any loose connectors.
• PCB relays: Listen for clicking relays when the machine should change functions. Intermittent or missing clicks may indicate failing relays, requiring PCB replacement.

When to call a technician: Intermittent faults can be difficult to trace; professional diagnostics are often necessary.
