Compressor Start or Overload Problem
Symptom
Pure Enrichment dehumidifier or humidifier trips the circuit breaker or GFCI outlet when turned on.
Electrical Short or Ground Fault
Symptom
Pure Enrichment dehumidifier runs but does not collect water; humidity in the room does not decrease.
No Dehumidification / Refrigeration Failure
Symptom
Pure Enrichment dehumidifier shows that it is running, but the bucket fills extremely slowly compared to rated capacity.
Reduced Dehumidification Efficiency
Symptom
Pure Enrichment dehumidifier’s auto mode does not maintain the set humidity; it cycles too frequently or not enough.
Humidity Control Calibration or Sensor Placement Issue
Symptom
Pure Enrichment dehumidifier’s continuous drain feature does not work; water still collects in the bucket or leaks.
Blocked or Improperly Installed Drain Hose
Symptom
Pure Enrichment dehumidifier’s fan does not run; compressor may start briefly then shut down.
Fan Motor Failure or Blockage
Symptom
Pure Enrichment humidifier base becomes unusually hot to the touch during operation.
Overheating of Power or Driver Circuit
Symptom
Pure Enrichment humidifier emits a strong musty or moldy odor when running.
Microbial Growth in Reservoir and Air Path
Symptom
Pure Enrichment humidifier leaks water from the base onto the table or floor during operation.
Tank Seal or Valve Leakage
Symptom
Pure Enrichment humidifier leaves white dust on nearby furniture and surfaces.
Mineral Aerosolization from Ultrasonic Operation
Symptom
Pure Enrichment humidifier makes loud buzzing or rattling noises during operation.
Fan or Transducer Vibration Noise
Symptom
Pure Enrichment humidifier turns on but shuts off after a few seconds; low-water or tank indicator flashes even when tank is full.
Water Level Detection Fault
Symptom
Pure Enrichment humidifier will not power on at all; no lights or response when pressing buttons.
Power Supply or Main PCB Failure
Symptom
Pure Enrichment humidifier’s auto-humidity mode never seems to reach the set humidity or overshoots significantly.
Inaccurate Humidity Sensing or Poor Sensor Placement
Symptom
Pure Enrichment humidifier’s buttons do not respond or respond only sometimes; unit may be stuck on one setting.
Keypad or Control PCB Fault
Symptom
Pure Enrichment humidifier’s night light or LED ring does not turn on, but mist output works normally.
LED Lighting Circuit Failure
Symptom
Pure Enrichment humidifier’s night light or LED ring works, but mist output is intermittent or cuts in and out.
Intermittent Transducer or Power Supply Issue
Symptom
Pure Enrichment ultrasonic humidifier powers on but produces no mist; water tank is full and indicator lights appear normal.
Ultrasonic Nebulizer (Transducer) Failure
Symptom
Pure Enrichment ultrasonic humidifier produces very weak mist output even on the highest setting.
Restricted Mist Path or Partial Transducer Scaling
