How to Fix F04 Error (Step-by-Step)

  1. Unplug the dryer from the electrical outlet to ensure your safety.
  2. Locate the drain pump, which is typically found behind the lower front access panel. You may need to remove a few screws to take off the panel.
  3. Place a shallow pan and a towel under the pump’s hoses to catch any water that will spill out.
  4. Squeeze the clamps on the hoses connected to the pump and slide them back, then carefully pull the hoses off the pump.
  5. Disconnect the electrical wire harness attached to the pump. Then, unfasten the screws or release the tabs holding the pump in place and remove it.
  6. Install the new drain pump by securing it in the same position as the old one. Reconnect the electrical harness and the hoses, ensuring the hose clamps are secure.
  7. Reattach the lower access panel, plug the dryer back in, and run a test cycle to check for proper drainage and any leaks.
  8. Turn the appliance off, wait about 2 minutes, then turn it back on.
