AEG Washer Error Code E3

E3 on an AEG washer signals a fault in the heating circuit. The code points to a defective heater element, a failed heating relay, or a problem with the electrical connections in the heater circuit. The machine uses this code to alert you that it cannot properly heat the water during a wash cycle. Diagnosis should start with testing the heater element and inspecting its connections.

You should not continue using the washer while E3 is active. A shorted heater element can pose an electrical hazard, and a failed relay or wiring fault may indicate damaged components that could worsen with continued use. The machine will also not heat water correctly, meaning wash results will be compromised. Address the fault before running additional cycles.

A reset may temporarily clear the E3 code from the display, but the error will return as soon as the machine attempts to heat water again if the underlying fault is not resolved. Resetting without repairing the heater element, relay, or connections does not fix the problem. The code should be treated as a prompt to diagnose and repair the heating circuit rather than dismissed with a reset.

Checking and reseating the heater element connections is a task many DIYers can handle safely with the machine unplugged. Replacing the heater element requires disassembling part of the washer and working near electrical components, which is manageable for those comfortable with appliance repair. Replacing the heating relay on the control board is more complex and may be better suited to a qualified technician. Always disconnect power before starting any inspection or repair.

If only the heater element needs replacement, parts typically cost in the range of $30 to $80, with labor adding $80 to $150 if a technician performs the work. A control board relay repair or full board replacement can push total costs into the $150 to $350 range depending on the board and labor rates in your area. Getting a diagnostic quote before committing to the repair is recommended.
