Ice maker does not power on at all; no lights, no display, no sound.

Safety first: Ensure the unit is unplugged before opening any covers. If you are not comfortable working with mains voltage, seek professional service.

• Check outlet: Test the wall outlet with another appliance to confirm it has power.
• Inspect power cord: Look for cuts, kinks, or burn marks. Replace the cord if damaged.
• Check main switch: If your Severin model has a physical power switch, verify it clicks and is not loose or stuck.
• Access control PCB: Remove the rear or bottom cover to reach the main PCB. Look for an onboard fuse near the power input. Test it with a multimeter and replace with the same rating if blown.
• Inspect for damage: Check the PCB for burnt components or discoloration. A failed power supply section often shows visible damage.
• Replace PCB if needed: If the fuse is intact but there is no low-voltage output to the display or controls, the internal power supply on the PCB may have failed. Replace the main control PCB.
