Washer-dryer combo will not run and displays F1 on the control panel.

Safety first: Always disconnect power before removing the console or touching electronic components.

• Power cycle: Unplug the unit for 5 minutes to discharge the control. Plug back in and attempt to start a cycle. If F1 returns immediately, proceed with inspection.
• Check supply voltage: Verify correct voltage at the outlet (typically 240V for combo units, 120V for control circuits) using a multimeter. Incorrect voltage can trigger control errors.
• Inspect wiring: Remove the top or rear console panel to access the main control board. Check all harness connectors for secure fit, corrosion, or burnt pins. Reseat each connector one at a time.
• Look for board damage: Examine the control board for burnt components, cracked solder joints, or moisture damage. If present, the board must be replaced.
• Replace control board: If wiring is intact and F1 persists, replace the main control board (electronic control) with the correct Amana part number for your model. Transfer any jumper plugs or settings as directed in the installation sheet.
• Professional help: If you are not comfortable working with live voltage or electronics, contact a qualified technician.
