E8 error; unit may not pump water to the evaporator tray, or may time out during the fill stage.

Safety first: Unplug the ice maker and remove water from the reservoir before removing the pump.

Steps to troubleshoot E8:

• Listen for pump operation: During the fill stage, you should hear the small circulation pump running. If it is silent or just hums, suspect a pump issue.
• Inspect for blockages: Remove the ice basket and access the pump intake screen. Clean any debris, scale, or slime that may restrict flow.
• Check tubing: Ensure the silicone hoses to and from the pump are not kinked or pinched.
• Verify electrical connection: Locate the pump wiring harness and confirm it is firmly plugged into the main PCB.
• Bench test the pump: With the pump removed and using a safe low-voltage test (per NewAir specs), verify that it runs. If not, replace the pump.
• Reinstall and test: Refit the pump, secure hoses with clamps, refill the reservoir, and run a cycle to confirm normal water circulation.
