Safety: Unplug the unit. Fan blades are sharp; wear gloves.

Steps:

Remove the rear or side panel to access the fan motor and blower wheel.
Check for obstructions such as plastic bags, insulation, or heavy dust buildup preventing the fan from turning. Clean thoroughly.
Spin the fan wheel by hand. It should rotate freely without grinding. If stiff or noisy, the motor bearings may be failing.
Inspect the fan motor wiring harness and connector at the main PCB. Reseat the connector and check for heat damage.
On models with a 3-wire fan (tach feedback), ensure the feedback wire is intact. A broken feedback line can trigger E8.
If the motor does not run when powered and wiring is good, replace the Dimplex fan motor assembly for your model.
Reassemble, restore power, and verify that airflow is strong and the E8 code is cleared.

Warning: Do not operate the unit with panels removed; this can expose live parts and disrupt airflow needed for safe operation.

Dehumidifier displays E8 and shuts down; fan may still operate
