Safety: Unplug the unit and allow it to cool for at least 30 minutes. Do not operate if there is a burning smell.

Steps:

Clean thoroughly: Remove the front and rear panels. Vacuum dust from the condenser coil (warm coil), fan blades, and air passages. Clean the air filter with mild soap and water; dry completely.
Check fan operation: Spin the fan blade by hand (with power disconnected). It should rotate freely without grinding. If stiff or noisy, the fan motor may be failing.
Power-on test: Reassemble, plug in, and run the unit. Confirm the fan starts immediately when the compressor is commanded on. If the fan does not run, replace the fan motor assembly.
Inspect thermal sensor/fuse: Some Bionaire units use a thermal fuse or thermostat attached to the condenser or compressor. If open, the unit may show E8 or shut down. Test continuity and replace if open.
Stop using if overheating persists: Continued E8 errors with a hot smell indicate a serious fault; discontinue use and seek professional service.

Dehumidifier shows E8 and shuts down; may restart after unplugging
