Devola dehumidifier makes loud rattling or grinding noises during operation.

Safety: Unplug the unit before touching moving parts.

• Identify noise source: Remove the front/rear covers and briefly run the unit (keeping hands clear) to locate whether the noise comes from the fan area or compressor area.
• Fan inspection: With power off, check that the fan wheel is tight on the motor shaft and not rubbing against shrouds. Tighten any retaining screws and reposition shrouds if needed.
• Remove debris: Clear any foreign objects from the fan housing.
• Compressor mounts: Inspect the rubber compressor mounts and mounting bolts. Tighten loose bolts and replace perished rubber mounts.
• Panel vibration: Tighten cabinet screws and, if necessary, add thin foam strips between vibrating panels.
