Maytag Washer Error Code d3/F74

The d3/F74 code signals a communication error within the User Interface Control board on your Maytag washer. This is the board that handles all the buttons, display, and cycle settings. The fault is often triggered by a power surge or voltage drop that disrupts the board's internal communication. It can be temporary or indicate a damaged UIC board.

A power reset clears the code and can fully resolve the issue if the root cause was a transient power event. To reset properly, unplug the washer and wait at least two minutes before plugging it back in. If the fault is caused by a physically damaged UIC board, the error will return after the reset.

If a power reset resolves the issue, the repair costs nothing. If the User Interface Control board has failed and needs replacement, parts and labor costs can range from roughly $150 to $350 or more depending on your location and the specific model. Getting a diagnostic visit from a qualified technician can help confirm whether the board is truly the failed component before purchasing parts.

Yes, the first step is something you can do yourself: clear the error code, unplug the washer, wait a full two minutes, and then restore power. If the code does not return, the issue was likely a temporary power disruption. If it comes back repeatedly, the UIC board may need to be inspected or replaced, which is a more involved repair.

When this error is active, the washer has halted operation and will not run a cycle, so there is no immediate safety hazard. However, you should not attempt to force the machine to run while the fault is present. Resolve the error through a power reset before using the washer again.
