Error Code: E51 Difficulty: Hard
Problem: Motor relay failure.
How to Fix E51 Error (Step-by-Step)
- Disconnect the dryer from the electrical outlet and confirm the error stays cleared during a full test cycle.
- Remove the top panel of the dryer to access the main control board.
- Locate the motor relay on the control board. It is a small, usually rectangular, component.
- Visually inspect the relay and the surrounding area on the circuit board for any signs of burning or damage.
- The motor relay is an integrated part of the main control board and cannot be replaced separately.
- If the relay is faulty, the entire main control board must be replaced.
- It is advisable to have a professional service confirm the diagnosis and perform the control board replacement.
- 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.

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.
