Maytag Washer Error Code d3/F73

The d3/F73 code indicates a User Interface Control failure or communication error within the UIC, which is the electronic board behind the washer's control panel. It means the UIC is either not functioning correctly or has lost communication with the main control board. Power surges and voltage drops are common triggers for this fault. In many cases the error is temporary and can be cleared with a full power reset.

When the d3/F73 fault is active, the washer may not operate normally or may not start at all, so running a wash cycle is generally not possible until the error is cleared. Attempting to force operation with an active control board fault is not recommended. Perform the power reset first, and if the error clears, monitor the washer closely during the next cycle.

Repair costs vary depending on the root cause. If only a power reset is needed, there is no parts cost. If the User Interface Control board needs replacement, parts and labor combined typically range from $150 to $350 depending on the specific model and local labor rates. A main control board replacement can bring costs higher, often in the $200 to $450 range, making it worth comparing repair costs against the age and overall condition of the washer.

A power reset is the first recommended step and will clear the fault if it was caused by a temporary electrical disturbance. To reset, unplug the washer and wait at least 2 minutes before restoring power. If the d3/F73 code returns after the reset, a component such as the UIC board, wiring harness, or main control board likely needs further inspection or replacement.

Start by clearing the error code and performing a full power reset: unplug the washer and wait 2 minutes before reconnecting power. If the code returns, inspect the wiring harness connectors between the UIC and the main control board for looseness or corrosion and reseat any loose connections. If the fault persists after that, the UIC board or main control board may need to be tested and replaced.
