AEG Washer Error Code EAB

The EAB code on an AEG washer means the triac for the DSP circuit on the main control board has been detected as defective. A triac is a semiconductor switching component that controls power delivery within the electronics. When it fails, the washer cannot complete its normal operation and displays this fault code. Resolving this error requires replacing the main control board electronics.

It is not advisable to continue using the washer while the EAB code is active. A defective triac on the control board can cause unpredictable electrical behavior, and the washer may not operate correctly or may fail to complete cycles. Continued use risks further damage to other control board components. The machine should remain off until the board has been inspected and replaced.

Resetting the washer by unplugging it and restoring power is unlikely to permanently clear the EAB error. Because the fault is caused by a physically defective triac on the control board, the error will return as soon as the machine attempts to use that circuit again. A reset may temporarily clear the displayed code, but the underlying hardware failure must be corrected by replacing the control board for a lasting resolution.

The recommended fix for EAB is replacing the main electronic control board, which is a moderately complex repair. A technician comfortable with appliance board replacement can perform this job with the correct replacement part. Component-level triac replacement is theoretically possible for someone with advanced soldering skills, but board replacement is the standard and more reliable approach. If you are not experienced with appliance electronics, professional service is recommended.

Repair costs for an EAB error primarily depend on the price of the replacement control board and labor. Control boards for AEG washers typically range from $150 to $350 or more depending on the model. Adding professional labor, total repair costs can range from $200 to $500 or higher. Getting a quote specific to your model before proceeding is recommended.
