Ice maker produces too much ice and does not stop even when the bin is full.

Safety: Disconnect power before cleaning sensors or replacing parts.

• Clean sensors: If your Bosch model uses optical sensors, clean both the emitter and receiver windows with a soft cloth.
• Check shutoff arm: For mechanical designs, ensure the shutoff arm moves freely and is not stuck in the down position. Replace the ice maker if the arm mechanism is broken.
• Test level switch: Use a multimeter to test continuity of the level switch as the arm moves. Replace if it does not change state.
• Replace ice maker or sensor: If cleaning and testing do not restore proper shutoff, replace the Bosch ice maker assembly or level sensor module.
