Error Code: C9 Difficulty: Hard
Problem: Communication error between the main board and the UI board.
How to Fix C9 Error (Step-by-Step)
- 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.
- If the error persists, disconnect the dryer from power again.
- Remove the top panel of the dryer by taking out the screws at the back.
- 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.
- 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.
- If replacing the UI board does not solve the issue, the main control board (Part 134557200NH) will need to be replaced.
- After replacing the faulty board, reassemble the dryer, restore power, and test its operation.
- Turn the appliance off, wait about 2 minutes, then turn it back on.
What to Check Next on This Electrolux Dryer
Focused repair path: dryer airflow, heating, motor, sensor, and control checks. Do not treat the fault as reset-only if it keeps returning; use the failed function to choose the next test.
- Disconnect power before opening panels, then confirm whether the Electrolux dryer repeats the same code after a clean reset.
- Match the symptom to the part of the cycle or function that fails: fill, drain, heat, cool, spin, latch, ignite, fan, sensor, or control response.
- Inspect simple causes first: airflow, water supply, drain path, door closure, filter, venting, wiring connectors, and visible damage.
- Use meter testing or service diagnostics before replacing electronic controls, because wiring, switches, sensors, and loads can mimic board failure.
- Use the complete Electrolux dryer model number from the appliance tag before ordering any model-specific part.
Check, inspect, clean, test, measure, remove, reconnect, clear, and replace parts only when the symptom supports that path. If these checks point toward a part, verify the complete Electrolux model number from the appliance tag before ordering.
Recommended Replacement Part
When It’s Better to Replace Than Repair
Dryer repairs are often worth it for small parts, but repeated heating, motor, drum, or control failures can point toward replacement.
Confirm gas vs electric, venting, voltage, doorway clearance, and laundry-space dimensions before ordering.
For repair parts, verify exact fit with the full dryer model number before buying; these links are general replacement-appliance shopping options.
