Dehumidifier runs but does not collect water; bucket remains dry even after hours of operation.

Safety: Unplug the unit before inspection. Refrigerant work must be done by a licensed technician.

• Check room conditions: Verify that humidity is actually high (use a hygrometer) and that the room temperature is within the unit's operating range.
• Inspect coils: Remove covers and inspect evaporator and condenser coils. Clean dust and lint with a soft brush and vacuum.
• Compressor operation: Plug in and run the unit briefly. Listen for the compressor starting (a deeper humming sound) and feel the condenser coil for warmth after a few minutes. If the compressor never starts, suspect the compressor start relay/overload or compressor itself.
• Check for frost pattern: If only a small part of the evaporator frosts or none at all, the system may be low on refrigerant or restricted.
• Call a professional: If cleaning does not restore water collection and compressor issues or refrigerant problems are suspected, contact a qualified appliance technician to test pressures, locate leaks, and repair the sealed system.
