AEG Washer Error Code E23

E23 indicates that the measurement circuit monitoring the drain pump triac is reading a fixed voltage of either 0V or 5V instead of a normal variable signal. The triac is the switching component on the main control board that regulates power to the drain pump. This fixed reading means the circuit cannot confirm whether the pump is being powered correctly. The fault is located within the control board electronics.

You should not continue using the washer while E23 is active. The fault indicates the drain pump control circuit is not functioning correctly, which means the machine may be unable to drain water properly. Running cycles with a failed drain control can lead to flooding or further electrical damage to the appliance.

The primary cost is the main control electronics board, which typically ranges from around $100 to $300 or more depending on the specific model. If you hire a technician, labor charges will add to that total, often bringing the full repair cost to somewhere between $150 and $450. Getting a firm diagnosis before ordering parts is advisable, as inspecting the wiring harness first could rule out a less expensive fix.

The primary repair for E23 is replacing the main control electronics board, which is a feasible DIY repair for someone comfortable working with appliance electronics. Before ordering a board, inspect the wiring harness between the board and the drain pump for any visible damage or shorts. If the harness is intact, board replacement is the next step. Always disconnect power before beginning any inspection or repair.

A power reset, such as unplugging the machine for a few minutes, is unlikely to permanently clear E23 because the fault points to a hardware failure in the triac measurement circuit rather than a temporary software or sensor glitch. The error will typically return as soon as the machine attempts to run a drain cycle. A proper repair of the underlying board fault is required to resolve the code.
