E04 displayed and ice maker stops; ice mold may be jammed with ice or not ejecting cubes.

Safety: Disconnect power before removing the ice maker assembly.

• Inspect for jams: Remove the ice bin. Look at the ice maker mold and ejector blades. If cubes are stuck or bridged together, gently break them apart with a plastic utensil. Do not use metal tools that can damage the coating.
• Check for obstructions: Ensure no foreign objects (plastic, packaging, etc.) are lodged in the ejector mechanism or under the ice maker.
• Manual test (if equipped): Some Bosch ice makers have a small test button or hole on the module. With power restored, press and hold to initiate a harvest cycle. If the motor hums but does not turn, or does nothing at all, the motor/module is likely faulty.
• Remove ice maker: Disconnect power again. Remove mounting screws and unplug the ice maker harness. Slide the assembly out carefully.
• Inspect gears and shaft: Open the cover on the ice maker module (if serviceable) and check for stripped plastic gears or a loose ejector shaft. If damaged, replace the entire ice maker assembly.
• Install new ice maker: Mount the new Bosch ice maker, reconnect the harness, and reinstall the ice bin. Restore power and allow several hours for ice production to resume.
