Bomann Unstable Power Supply / Control Panel Issue

Display or indicator lights flicker or go dim while the unit is running.

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

Loose mains plug, Faulty power cord, Failing control PCB voltage regulator, Poor connection between display and main board

Safety first: Unplug the appliance before inspecting the cord or plug.

Steps:

Check plug fit: Ensure the plug fits firmly in the outlet and does not wobble.
Inspect cord: Look for damage, cuts, or kinks along the power cord. Replace the cord if damaged.
Try another outlet: Use a different wall socket to rule out a loose or faulty outlet.

If flickering persists, the internal power supply on the control board may be failing and should be replaced by a technician.
