Whirlpool Washer Error Code F73

F73 indicates that the User Interface Control (UIC) microprocessor is unable to read or verify the EEPROM memory on the control board. As a result, the washer disables cycle selection and price display functions until the code is manually cleared. The code can also signal a broader internal communication failure within the UIC. It will not clear on its own and requires manual intervention through diagnostic mode.

When the F73 error is active, the washer disables cycle selection, which means you will generally not be able to start a wash cycle normally. Attempting to force operation through a partially functional control board is not recommended, as the root cause may involve an unstable control board that could behave unpredictably. It is best to resolve the error before returning the washer to regular use.

A reset clears the stored error code from memory and may resolve the issue if it was caused by a temporary power anomaly. However, if the underlying cause is a physically failed EEPROM or a damaged UIC board, the F73 code will return the next time the washer attempts to read its memory, often immediately after power is restored. A permanent fix requires addressing the root hardware failure, which typically means replacing the UIC board.

You can attempt a reset first by clearing the error code, unplugging the washer, and waiting a full 2 minutes before restoring power. This allows the microprocessor to fully restart and may resolve the issue if the cause was a temporary power event or firmware glitch. If the F73 returns after the reset, the UIC board itself is likely faulty and will need to be replaced, which is a more involved repair. Checking wiring harness connections at the UIC board is also a no-cost step worth doing before purchasing parts.

If the issue is resolved by a reset alone, there is no parts cost. If the UIC board requires replacement, parts typically range from around $80 to $200 depending on the specific model. Adding professional labor for diagnosis and board replacement can bring the total repair cost to approximately $150 to $350. Getting a diagnosis to confirm the UIC is the failed component before purchasing parts is advisable, since other wiring or connector issues can sometimes produce similar symptoms.
