Ice maker will not power on, display is dark, no interior lights or sounds

Safety first: Disconnect the ice maker from mains power by unplugging it or switching off the circuit breaker before removing any panels.

Step-by-step checks:

• Verify wall outlet: Plug a lamp or another appliance into the same outlet to confirm there is power. If no power, check the household breaker or RCD.
• Inspect power cord: Pull the unit forward and visually inspect the Siemens power cord and plug for cuts, burns, or kinks. If damaged, replace the power cord assembly.
• Check terminal block: Remove the rear lower cover (usually held by Torx or Phillips screws). Inspect the terminal block where the cord connects to the unit for loose screws, discoloration, or melted plastic. Tighten loose screws; if burned, replace the terminal block.
• Examine line filter and wiring: Many Siemens ice makers use an EMI line filter between the cord and main PCB. Check for burnt smell or bulging components. Replace the line filter module if damaged.
• Control board fuse: Remove the control panel or top cover to access the main control PCB. Look for an onboard glass or thermal fuse. If the fuse is open, replace the fuse only after identifying and correcting any shorted wiring or components.

When to call a technician: If the main control PCB shows burn marks, or if replacing the fuse blows again immediately, a qualified Siemens technician should test and replace the control module.
