How to Fix / Troubleshooting
Safety: Unplug the appliance.
- Check for overfill: If the drum is full of water, manually drain via the pump filter and then inspect the pressure system.
- Clean and inspect pressure hose: Remove and flush the hose, ensuring no soap or lint blockage.
- Verify sensor type: Ensure the correct dual-level pressure sensor is fitted for your Zanussi model; incorrect parts can trigger E34.
- Replace sensor: If cleaning does not help, replace the dual-level pressure sensor and clear the error by running a test cycle.
