How to Fix / Troubleshooting

Safety first: Disconnect mains power before internal checks.

  • 1. Power reset: Unplug the washer for 10–15 minutes and restart the program.
  • 2. Observe pattern: Note if the freeze always occurs at the same stage (e.g. heating, draining, spinning) to narrow down the subsystem.
  • 3. Check key sensors: Inspect and reseat connectors for the pressure sensor, NTC, and motor tachometer.
  • 4. Ventilation: Ensure the control module area is not blocked and that the washer is not installed in a very tight, unventilated space.
  • 5. Technician service: Persistent freezing may require firmware update or control module replacement by a V-ZUG technician.
