Maytag Washer Error Code F73/F74

F73 and F74 on a Maytag washer indicate a User Interface Control failure or communication error within that control subsystem. The UIC is the electronic board behind the control panel responsible for processing inputs and communicating with the rest of the machine. These codes are often triggered by power surges or drops but can also point to a hardware fault in the UIC board or its wiring connections.

The washer will typically stop operation when these codes appear, which means attempting to run a cycle may not be possible until the fault is cleared. It is best to perform the reset procedure before using the machine again. If the code returns repeatedly, continued use should be avoided until the underlying cause is diagnosed, as a malfunctioning control board can produce unpredictable behavior.

Start by clearing the error code on the control panel, then unplug the washer and wait two minutes before restoring power. If the code does not return, the problem was likely a temporary power issue. If it comes back, inspect the wiring harness connectors between the UIC and main control board for looseness or corrosion and reseat them firmly. Persistent faults after these steps usually require replacing the UIC board.

A reset can clear these codes if a power disturbance was the root cause. To reset, clear the error code on the display, then unplug the washer from the outlet and wait at least two minutes before reconnecting power. If the code returns immediately or after the next wash cycle, a hardware issue such as a loose connector or a failing UIC board is likely involved.

If the issue is resolved with a simple power reset, there is no parts cost involved. If the UIC board needs replacement, parts alone typically range from $80 to $200 depending on the model, with professional labor adding another $100 to $200. If the main control board is also involved, total repair costs can be higher, so it is worth getting a diagnostic assessment before committing to parts.
