Ice maker will not power on, display is blank or shows E0 shortly after plugging in.

Safety first: Unplug the ice maker from the wall outlet before removing any panels. Do not work on live circuits.

• Check power supply: Verify the outlet has 120V AC using a meter or by plugging in another appliance. If there is no power, reset the breaker or use a different outlet.
• Inspect power cord: With the unit unplugged, check the Hotpoint power cord for cuts, burns, or kinks. Replace the cord set if damaged.
• Access control board: Remove the rear or lower service panel (usually held by Phillips screws). Locate the main control board module.
• Check harness connections: Reseat all multi-pin connectors going to the control board and user interface. Look for bent pins, corrosion, or burnt spots on the board.
• Visual inspection: If you see burnt components or bulging capacitors on the PCB, the board is likely faulty and should be replaced.
• Replace control board: Order the correct Hotpoint main control board by model number. Transfer any wiring one connector at a time to the new board. Reassemble panels and test.

If the unit still shows E0 or remains dead after these checks, contact a qualified appliance technician for board-level diagnostics.
