E8 error; water pump may not run, or unit beeps with no water circulation; no ice production.

Safety first: Unplug the ice maker and empty the reservoir before removing the pump.

Check for simple blockages:

• Remove the ice basket and inspect the water pump intake screen at the bottom of the reservoir. Clean any debris, scale, or slime with a soft brush and mild detergent, then rinse thoroughly.
• Refill with clean water and restart. Listen for the pump running (a soft humming sound) and watch for water flowing over the evaporator grid.

Bleed air from the pump:

• If the pump is humming but not moving water, tilt the unit slightly forward and backward a few times (while off) to help release trapped air, then restart.

Inspect pump and wiring:

• Unplug again. Access the circulation pump from the bottom or side panel.
• Check that the pump connector is firmly attached to the control board and that wires are intact.
• Remove the pump and inspect the impeller for obstructions or damage.

Next steps:

• If the pump does not run at all when powered, replace it with a compatible AGLUCKY water circulation pump.
• If a new pump does not resolve E8, the control board pump driver circuit may be faulty and require replacement.
