Possible Causes

How to Fix / Troubleshooting
Safety first: Unplug the unit. Fan blades can be sharp; keep fingers clear.
Step-by-step:
- 1. Inspect air path: Remove the air filter and check for plastic bags, insulation, or debris stuck in the fan area. Remove any obstructions.
- 2. Spin the fan by hand: With the cover removed, gently rotate the fan wheel. It should spin freely without scraping. If it is stiff or rubbing, check for misalignment or foreign objects.
- 3. Check fan motor wiring: Locate the fan motor connector on the PCB and reseat it. Inspect the harness for damage.
- 4. Test operation: Reassemble enough to run safely, then power on. If the fan does not start or runs erratically and E7 appears, the motor may be failing.
- 5. Replace fan motor: Remove the fan shroud, detach the fan blade from the motor shaft, and unbolt the motor. Install a compatible De'Longhi fan motor, transfer the fan blade, and reconnect wiring.
- 6. PCB diagnosis: If a new motor does not resolve E7, the fan drive circuit on the main PCB may be defective and requires board replacement.
