Safety: Unplug the humidifier and remove the water tank before opening.

Steps:

Check for obstructions: Look through the air outlet and intake for foreign objects, dust clumps, or filter material blocking the fan. Remove any debris.
Access fan: Remove the housing screws and carefully lift off the cover to expose the fan assembly.
Spin test: Gently spin the fan blades by hand. They should rotate freely without grinding or resistance. If stiff, clean the hub and remove any buildup.
Inspect wiring: Ensure the fan motor connector is firmly attached to the main PCB and wires are not damaged.
Test operation: With the unit reassembled enough for safe operation, briefly power on to see if the fan starts. If it does not, the motor or driver is faulty.
Replace fan motor: Remove the fan assembly (usually held by screws or clips) and install a new Levoit‑compatible DC fan motor. Reconnect wiring and reassemble.
Control board: If a new fan does not run and E8 persists, the fan driver on the main PCB is likely defective and the board should be replaced.

Levoit humidifier shows E8 and shuts off, often shortly after starting.
