A23 meaning for this display codeset

This page isolates Eco Alliance fault code A23 for the LE-series LED operation-panel display. It does not combine the Eco Alliance A23 meaning with another controller or codeset.

Before applying the Eco Alliance A23 meaning, confirm the affected model uses the LE-series LED operation-panel display. In that controller namespace, A23 means documented as a high-pressure temperature-sensor fault.

The Eco Alliance LE Series Heat Pump Water Heater Instruction Manual source anchor on page 13 supports this Eco Alliance A23 record for the LE-series LED operation-panel display.

The permanent source key eco-alliance-le-series-display A23 keeps the eco-alliance-le-series-display A23 controller/code pairing distinct in publication.

What the documentation says

Documented as a high-pressure temperature-sensor fault.

This is a paraphrase of the manufacturer’s documentation. A licensed technician confirms the actual cause.

Severity

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.
