E5 error displayed; ice maker may stop mid-cycle or fail to harvest ice properly.

Safety first: Unplug the ice maker before cleaning sensors or removing covers.

Steps to fix E5:

• Empty the ice basket: Remove all ice from the storage bin. Overfilled bins can block the sensor and trigger E5.
• Locate the ice full sensor: On many Costway models, this is an infrared pair (emitter and receiver) mounted on opposite sides of the ice chute or bin opening, or a single optical sensor above the bin.
• Clean the sensor lenses: Use a soft, lint-free cloth slightly dampened with water or glass cleaner to gently wipe the sensor windows. Dry completely.
• Check alignment: Ensure the emitter and receiver face each other directly and that their brackets are not bent. Adjust the brackets gently if needed so the beam path is clear.
• Inspect wiring: Follow the sensor wires back to the control board. Confirm connectors are fully seated and wires are not pinched or broken.
• Test operation: Plug the unit back in and start a cycle. When the bin is empty, the E5 code should clear. Slowly add ice and confirm the unit stops when the bin is full.
• Replace sensor if defective: If E5 appears even with a clean, empty bin and good wiring, replace the Costway ice full sensor / infrared level sensor assembly.
