Ice maker shows E19; internal clock or cycle timing is lost, causing irregular or aborted ice cycles.

Safety first: Disconnect power before touching electronics.

• Power cycle: Unplug the unit for 5–10 minutes to reset the control. Plug back in and observe if normal timing resumes.
• Check supply voltage: Ensure the outlet provides stable voltage within the specified range. Avoid using long, undersized extension cords.
• Inspect control board: Look for obvious damage near timing components (crystals, oscillators). Any burnt or cracked parts indicate the board should be replaced.
• Firmware update (if applicable): If Hansa provides a service update procedure, follow it to reload or update firmware.
• Replace PCB: If timing issues persist, replace the main control board with the correct model-specific part.
