Maytag Washer Error Code d23

The d23 code means the Central Control Unit (CCU) is not receiving communication from the User Interface Control (UIC). This breaks down the link between the control panel and the main control board, disabling cycle selection and the price display. The fault can stem from a loose wiring connection, a damaged harness, or a failure in either control board. The error will persist until the underlying cause is resolved or the code is manually cleared.

The d23 error disables cycle selection and the display while it is active, so normal operation is not possible. You should not attempt to force the washer to run while this fault is present. Address the communication fault before resuming use to avoid further stress on the control components.

The d23 error can be manually cleared, but clearing it does not fix the underlying communication problem. If the fault condition still exists, the code will return after the reset. A reset is useful for confirming whether the fault is intermittent, but a full diagnosis of the wiring and control boards is necessary for a lasting repair.

Some causes of d23 are within reach of a knowledgeable DIYer. Checking and reseating the wiring harness connectors between the UIC and CCU does not require special tools. However, accurately testing control boards and replacing them requires familiarity with appliance electronics. If basic wiring checks do not resolve the issue, a qualified technician should handle further diagnosis.

Repair costs vary depending on the failed component. If the issue is simply a loose or corroded connector, the repair may cost little to nothing beyond your time. Replacing a UIC or CCU typically involves parts costs ranging from $80 to $300 or more per board, plus labor if a technician is hired. Getting a diagnostic assessment before ordering parts will help avoid unnecessary expenses.
