Electrolux Washer Error Code ED3

ED3 indicates a fault in the drying heating element relay 2 circuit on your Electrolux washer-dryer. The control system has detected an issue involving the relay responsible for activating the drying heating element. Possible causes include faulty wiring between the WD board and thermostats, defective thermostats, a faulty WD board, or a defective main PCB. The drying cycle will typically not function correctly while this error is active.

The washing function may still operate while ED3 is active, but you should not attempt to run a drying cycle until the fault is resolved. A faulty relay in the heating circuit could cause improper heating behavior, which poses a potential safety risk. It is best to avoid using the drying function until the cause of ED3 has been properly diagnosed and corrected.

A power reset may temporarily clear the ED3 code from the display, but if the underlying fault in the relay circuit, wiring, thermostats, or boards is still present, the error will return as soon as the machine attempts a drying cycle. A reset is useful as a first step to confirm whether the fault is intermittent, but it does not fix the root cause. Proper diagnosis and repair of the faulty component are required for a lasting resolution.

Some aspects of this repair are accessible to a knowledgeable DIYer. You can start by inspecting and reseating the wiring connectors between the WD board and the thermostats, and testing the thermostats for continuity with a multimeter. However, diagnosing and replacing the WD board or main PCB requires more technical skill and comfort working with appliance control electronics. If you are unsure, it is safer to consult a qualified appliance technician.

Repair costs vary depending on the root cause. Thermostat replacement is typically on the lower end, often ranging from around $50 to $150 including parts and labor. WD board or main PCB replacement is more expensive, with costs generally ranging from $150 to $400 or more depending on parts availability and labor rates in your area. A wiring repair may cost less if only a connector or section of harness needs attention.
