Ice maker displays E04 and stops mid-cycle, water remains in the sump or tray

Safety: Unplug the Iceman ice maker before accessing the drain pump or hoses.

• 1. Inspect external drain hose: Check that the drain hose from the back or base of the unit is not kinked, elevated too high, or submerged in standing water. Straighten and reroute as needed.
• 2. Clear clogs: Disconnect the drain hose from the unit and run water through it at a sink. Use a flexible brush or pipe cleaner to remove any scale or debris.
• 3. Check internal drain port: Open the ice bin and locate the internal drain opening in the sump or reservoir. Remove any ice, scale, or foreign objects blocking the port.
• 4. Test drain pump: Access the drain pump (usually at the base). Inspect for broken impeller blades or obstructions. Spin the impeller by hand; it should move freely. Test the pump coil for continuity. If open or seized, replace the drain pump assembly.
• 5. Run a test cycle: Reassemble, restore power and water, and run a cleaning or ice-making cycle to confirm proper draining and that the E04 code clears.

Tip: Regular descaling with an approved ice machine cleaner helps prevent drain blockages from mineral buildup.
