Possible Causes

Safety first: Disconnect mains power before removing the door panel.

Check connections: Ensure the UI board connectors and ribbon cables are fully seated.
Verify part compatibility: If the UI was replaced, confirm it matches the exact Zanussi model and PNC.
Service reconfiguration: Some models require configuration via service mode after board replacement. Contact a Zanussi service center.
