How to Fix Electrolux dryer Error C9

Error Code: C9 Difficulty: Hard

Problem: Communication error between the main board and the UI board.

How to Fix C9 Error (Step-by-Step)

1. First, perform a hard reset by unplugging the dryer from the power outlet for at least 10 minutes. Then, plug it back in and see if the error clears.
2. If the error persists, disconnect the dryer from power again.
3. Remove the top panel of the dryer by taking out the screws at the back.
4. Locate the main control board and the user interface (UI) board. Carefully check the wire harness that connects the two boards. Unplug and securely reconnect it to ensure a firm connection.
5. If the connection is secure and the error remains, the user interface board (Part 5304521373) is the most likely component to have failed. Carefully disconnect the wires and remove the old board to install the new one.
6. If replacing the UI board does not solve the issue, the main control board (Part 134557200NH) will need to be replaced.
7. After replacing the faulty board, reassemble the dryer, restore power, and test its operation.
8. Turn the appliance off, wait about 2 minutes, then turn it back on.

Still Not Working?
If the replacement part didn’t fix the issue, you may have a wiring problem or main board failure.
