IceKing ice maker shows E17; unit may stop with water remaining on the evaporator or in the sump.

Safety first: Unplug the ice maker before accessing the pump or water system.

Step-by-step checks:

• 1. Access circulation pump: Remove the ice bin and internal panels to locate the circulation pump that moves water over the evaporator.
• 2. Inspect for debris: Check the pump inlet and impeller area for scale, ice chips, or foreign objects. Clean thoroughly.
• 3. Check wiring: Ensure the pump connector is secure and wires are intact.
• 4. Listen for operation: After reassembly, plug in and start a cycle. Listen for the pump running. If it hums but does not move water, the impeller may be jammed or the motor weak.
• 5. Replace pump: If cleaning does not restore normal operation, replace the circulation pump assembly.

When to call a technician: If the pump is difficult to access or integrated with other components, a technician can perform the replacement and bleed air from the system.
