Possible Causes
Refrigerant leak in indoor or outdoor coil, Blocked expansion device or capillary, Severely dirty evaporator coil, Faulty low-pressure sensor or switch
How to Fix / Troubleshooting
Safety: Refrigerant is under pressure and must only be handled by licensed personnel. Do not attempt to open the sealed system.
User checks:
- Clean indoor filters and coil: Remove and wash filters. If the evaporator coil is visibly clogged with dust, gently vacuum or use a soft brush. Avoid bending fins.
- Check airflow: Ensure supply and return air are not blocked by furniture, curtains, or covers.
- Observe frost: If you see heavy ice buildup on the indoor coil or refrigerant lines, turn the unit off and let it thaw completely. Then run again. If E8 recurs, a refrigerant issue is likely.
Technician tasks:
- Leak test the system and repair any leaks.
- Evacuate and recharge with the correct refrigerant type and weight specified by Electrolux.
- Test/replace the low-pressure sensor or switch.
Persistent E8 faults require professional service.
