How to Fix / Troubleshooting

Safety First: Unplug the washer before accessing internal components.

  • Step 1 – Verify parts: If a board was recently replaced, confirm the part number matches the exact model and revision of your Roper washer.
  • Step 2 – Reseat connectors: Disconnect and reconnect the harness between the UI and main control, ensuring all connectors are fully seated.
  • Step 3 – Inspect harness: Check for pinched, cut, or abraded wires between the console and main control. Repair or replace as needed.
  • Step 4 – Power cycle: Restore power and attempt to enter diagnostic mode (per service manual) to clear stored errors.

If F2E3 persists with correct, matching parts and good wiring, one of the boards may be defective and should be replaced as a matched set if specified by the manufacturer.
