Washer-dryer stops mid-cycle and door remains locked with water inside, but no error code displayed

Safety first: Unplug the appliance before internal inspection. Do not force the door open.

Step-by-step checks:

• 1. Check power stability: Ensure the plug is firmly in the socket and not overheating. Avoid multi-plug adapters.
• 2. Inspect control board: Remove the top cover and inspect the main PCB for signs of overheating or loose connectors.
• 3. Door lock: If the machine frequently stops and then resumes after tapping the front, the door lock may be intermittent. Replace it.
• 4. Pump and motor: Overheating motors or pumps can trip internal protection and stop the cycle. Check for obstructions and ensure cooling vents are clear.
• 5. Technician diagnosis: Intermittent faults can be complex; if basic checks do not resolve the issue, seek professional service.
