Possible Causes

Corrupted EEPROM data, Failed main control board memory chip, Voltage spike damage to PCB

How to Fix / Troubleshooting

Safety: Disconnect from mains before any work.

Steps:

  • Power cycle: Unplug the unit for at least 15 minutes, then plug back in. Sometimes a temporary memory glitch can clear.
  • Check power quality: Ensure the unit is not connected through a faulty extension cord or power strip. Plug directly into a properly grounded wall outlet.
  • Surge protection: If E9 occurred after a storm or power surge, the PCB may be damaged. Use a surge protector in the future.
  • Board replacement: EEPROM faults on Olimpia Splendid dehumidifiers are typically not field-reprogrammable. Replace the main control PCB with the correct part number for your model.
  • Professional service: Because this involves handling and transferring wiring to a new PCB, a qualified technician is recommended.
