What the documentation says

Amber — service attention

Amber means the fault needs attention; contact the manufacturer or a licensed technician if it persists.

Repair, replacement and warranty context

Start with diagnosis, then compare repair and replacement

An amber classification usually calls for a diagnosis and repair quote, not automatic replacement. Compare parts availability, repair cost and system age only after the fault has been confirmed by an appropriately licensed professional.

This brand has a verified current Australian support route, so check warranty coverage with the manufacturer before authorising paid repair or replacement work.
