Washer-dryer combo will not drain; control may click but pump does not run, or E23 appears shortly after drain is requested.

Safety first: Disconnect power before accessing internal components.

• Confirm pump is not mechanically blocked: Follow the steps for E21 to ensure the pump and hoses are clear of debris.
• Check wiring at pump: Inspect the pump connector for burned pins, loose terminals, or damaged insulation. Repair or replace the harness if needed.
• Test pump resistance: Using a multimeter, measure resistance across the pump terminals (typically 10–40 ohms; refer to Frigidaire service data). An open or shorted reading indicates a bad pump.
• Inspect main control board: Access the control board (usually behind the top or rear panel). Look for burned spots or damaged solder joints near the pump relay. If the relay is visibly damaged or the board smells burnt, the control board must be replaced.
• Replace failed component: If the pump tests bad, replace the drain pump. If the pump is good but not receiving power during drain, replace the main control board.

Because this involves live-voltage circuits and board-level components, many homeowners prefer to have a professional perform final diagnosis and replacement.
