AEG Display Power / Backlight Fault

Display or indicator lights flicker or are very dim.

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

Failing display backlight LEDs, Poor connection on display ribbon cable, Weak low-voltage supply on PCB, Aging capacitors in power circuit

Safety: Unplug before opening the control panel.

Check mains stability: Ensure the machine is not on an overloaded circuit causing voltage drops.
Inspect ribbon cable: Remove the front panel and reseat the ribbon cable between the display and main PCB.
Visual PCB check: Look for bulging capacitors in the low-voltage section and replace the PCB if necessary.
Replace display: If only the display is dim while other functions are normal, replace the display module.
