How to Fix / Troubleshooting

Safety: Turn off the unit and isolate power before working near water and electrical parts.

  • Check drain outlet: On Olimpia Splendid wall units, remove the front cover and inspect the drain pan at the bottom of the evaporator for standing water.
  • Clear blockage: Use a flexible brush or wet/dry vacuum on the drain outlet to remove sludge and debris.
  • Verify hose slope: Ensure the drain hose slopes continuously downward with no upward loops or kinks.
  • Clean with mild biocide: Flush the drain line with a mixture of water and a small amount of mild disinfectant to reduce algae growth.
  • Inspect pan: If the drain pan is cracked or warped, it may need replacement by a technician.
