AEG Timer / Auto-Restart Logic Fault

Dehumidifier auto-restart or timer functions do not work correctly

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Incorrect user settings, Corrupted control board memory, Faulty real-time clock circuit on PCB

Safety: Unplug before extended handling.

Reset settings: Cancel all timers and auto modes via the control panel. Then set a simple on/off timer and test.
Factory reset: Perform a factory reset if supported by your AEG model.
Power cycle: Unplug for 10–15 minutes to clear transient memory issues.
PCB replacement: If timer and auto-restart remain unreliable, the main control PCB may have a logic or RTC fault and require replacement.
