Electrolux Washer Error Code EDD

The EDD code on an Electrolux washer-dryer indicates a WDM ground current leakage alarm. The control board has detected that the sensing voltage at the line WD relay is outside of acceptable limits, which points to possible current leakage between the drying heating element and earth ground. This is a safety fault that prevents the drying function from operating until the issue is resolved.

A power reset may temporarily clear the EDD code, but if the underlying cause is an insulation fault in the heating element or damaged wiring, the code will return as soon as the drying cycle is attempted again. Because this is a safety-related fault, it is important to diagnose and repair the root cause rather than relying on resets.

Repair costs depend on the root cause. Replacement of the drying heating element typically ranges from around 80 to 200 dollars for the part, plus labor costs that can add another 80 to 150 dollars depending on your location and the technician. If the fault is traced to the WDM control module, parts costs are generally higher, potentially ranging from 150 to 350 dollars or more before labor is included.

You should not use the appliance in drying mode while the EDD code is active. The fault indicates potential current leakage from the heating element to the chassis, which is a shock hazard and a potential fire risk. The washing function may still operate, but the appliance should be inspected by a qualified technician before the drying function is used again.

The first step is to test the drying heating element for current leakage by measuring insulation resistance between the heater terminals and the appliance chassis ground using a megohmmeter. If the element shows low insulation resistance, it needs to be replaced. If the element tests normal, inspect the heater wiring harness and terminal connections for damage, corrosion, or moisture before considering the WDM control module as a cause.
