Samsung Error Code E458 / 458

Samsung Error Code E458 (or 458) often indicates a drainage fault or water leak detection (model dependent). The unit may detect water build-up in the drain tray and shut down to prevent overflow and damage.

Common causes include blocked drain lines, mould and sludge build-up, incorrect drainage fall, or drain pump failure. Homeowners may notice water leaking from the indoor unit or damp patches around the system.
