Bomann Control Input / Start Circuit Fault

Unit powers on but will not start an ice-making cycle when the start button is pressed.

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

Start button failure on control panel, Child lock or pause mode active, Faulty control PCB, Loose ribbon cable between display and main board

Safety first: Disconnect power before removing any control panel parts.

Steps:

Check indicators: Ensure no error codes or ICE FULL / ADD WATER warnings are active. Resolve those first.
Disable lock modes: If your Bomann model has a lock function, hold the lock/unlock button (often 3–5 seconds) to disable it.
Power cycle: Unplug for 5 minutes, then plug back in and try again.

If the start button still does not respond, the keypad or control PCB may be defective and should be tested and replaced by a technician.
