Bucket Full / Drain System Protection
PF
Dehumidifier displays PF and stops; may occur after a power outage or surge.
Power Failure / Voltage Interruption
Symptom
Dehumidifier display and buttons work, but unit does not respond to changes in humidity setting (runs constantly or not at all).
Humidity Control Failure
Symptom
Dehumidifier display is dim, flickering, or segments are missing, but the unit may still run.
Display / User Interface Failure
Symptom
Dehumidifier emits a burning or electrical smell during operation.
Overheating Electrical Component
Symptom
Dehumidifier fan does not run; compressor may start and quickly shut down or unit shows error codes related to overheating.
Fan Motor Failure / Airflow Loss
Symptom
Dehumidifier frequently trips the household circuit breaker or blows fuses.
Excessive Current Draw / Electrical Short
Symptom
Dehumidifier has a musty or moldy odor from the air outlet.
Biological Growth in Water Path
Symptom
Dehumidifier ices up; evaporator coil covered in thick ice and airflow is reduced.
Evaporator Coil Icing / Defrost Failure
Symptom
Dehumidifier leaks water onto the floor instead of into the bucket or drain hose.
Water Leak / Drainage Failure
Symptom
Dehumidifier makes loud rattling or vibrating noises during operation.
Excessive Vibration / Loose Components
Symptom
Dehumidifier operates but causes noticeable radio or TV interference nearby.
Electromagnetic Interference (EMI)
Symptom
Dehumidifier powers on but compressor never starts; fan runs continuously and no water is collected.
Compressor Start Failure
Symptom
Dehumidifier runs briefly then shuts off; may restart after a few minutes and repeat the cycle.
Short Cycling / Overheat or Protection Trip
Symptom
Dehumidifier runs but airflow from the front grille is weak.
Restricted Airflow
Symptom
Dehumidifier runs but does not collect water; bucket remains dry even in humid conditions.
No Dehumidification / Sealed System or Airflow Failure
Symptom
Dehumidifier shuts off and displays that the bucket is full even when the bucket is empty and properly installed.
False Bucket Full Detection
Symptom
Dehumidifier turns on by itself or changes settings without input.
Control Logic / Keypad Malfunction
Symptom
Dehumidifier will not power on at all; no lights or display.
No Power / Dead Control
Symptom
Dehumidifier’s continuous drain feature does not work; water still fills the bucket.
Continuous Drain Failure
Symptom
Dehumidifier’s humidistat reading is inaccurate compared to other hygrometers.
