This issue typically manifests as the washer failing to start, stopping mid-cycle, or the drum not spinning properly. It's crucial to address this error promptly, as it indicates a disruption in the washer's control system that may be due to faulty or loose wiring.

Common Symptoms:

  • Washer fails to start or stops mid‑cycle
  • Drum fails to spin or exhibits erratic movement
  • Error code F28 is displayed on the control panel

Possible Causes

  • Faulty or loose wiring harness/connector between CCU and MCU (medium)

How to Fix Error F28

DIY Fix Check basic connections and reset power

  1. Unplug the washer from its power source for at least 1–2 minutes.
  2. Inspect the power cord and wall outlet to ensure stable power.
  3. Reconnect and power on the washer to see if the F28 error clears.

Technician Only Inspect and secure communication harness between CCU and MCU

  1. Disconnect power to the washer.
  2. Remove access panels to locate the communication harness between the central control unit and motor control unit.
  3. Inspect connectors for loose pins, corrosion, or damage.
  4. Reseat the harness firmly in both CCU and MCU connectors.
