No water may be normal when room RH is already below the set point. If RH is high, check mode, temperature, airflow, frost, bucket seating, and the continuous-drain route. A running fan does not prove the compressor is removing moisture.
What matters most
- Confirm high RH with a separate meter.
- Some units run the fan after the compressor stops.
- Do not open a sealed refrigeration system yourself.
Confirm that collection should be happening
Compare actual room RH with the selected target and make sure the appliance is not in fan-only, comfort, or scheduled mode.
Place a second hygrometer away from the exhaust and allow enough time for it to stabilize.
Check simple interruptions
Reseat the bucket, clean the filter, clear the grilles, inspect for ice, and verify that a drain hose is not routing water somewhere unexpected.
Listen for a change in sound when the compressor starts, but do not rely on sound as the only test.
Know the service boundary
Within-range temperature, clean airflow, a correct set point, and high verified RH should produce water. If they do not, review warranty and recall status and contact authorized service.
Do not bypass bucket switches, thermal controls, or grounding protections.
A measured action plan
- 1Verify room RH and target mode.
- 2Reseat the bucket and inspect the drain path.
