Whirlpool Washer Error Code d3

The d3 code on a Whirlpool washer indicates a UI EEPROM error or UIC EEPROM error. It is the AccuTrac display equivalent of fault codes F73 and F74. The error means the washer has detected a problem with the memory chip on the User Interface Control board, which stores essential operating data. This can be caused by a power disruption, corrupted memory, a wiring issue, or a failed UIC board.

The d3 error typically prevents the washer from operating normally, as the control system cannot read valid data from the UIC EEPROM. You should not attempt to force the washer through a cycle while this fault is active. Address the error by performing a power reset first, and if the code persists, have the washer serviced before running additional loads.

Replacing the UIC board is a moderately involved repair that requires disconnecting power, accessing the control panel assembly, and carefully transferring wiring harness connectors to the new board. Technicians and experienced DIYers with basic appliance repair skills can often complete this repair. Always unplug the washer before beginning any disassembly, and confirm the replacement board is compatible with your specific model number before purchasing.

Unplugging the washer and disconnecting power for at least two minutes is always the recommended first step when a d3 code appears. This allows the control system to fully power down and may clear a temporary fault caused by a voltage spike or interrupted cycle. If the code returns after restoring power, the underlying cause is likely a hardware issue such as a failed UIC board or a damaged wiring connection.

If the d3 error requires a User Interface Control board replacement, parts typically range from around $80 to $200 or more depending on the specific model. Adding professional labor, total repair costs can range from roughly $150 to $350. If the fault is caused only by a loose wiring harness connection, the repair cost may be limited to a service call fee.
