Maytag Washer Error Code d8

The d8 code on a Maytag washer indicates a UIC microprocessor or EEPROM fault, specifically an F73 or F74 error. The control board's microprocessor is unable to read or verify the data in its EEPROM memory, or the memory has failed a CRC integrity check. This causes the cycle selector and display to be disabled until the code is manually cleared.

When d8 is active, the washer disables cycle selection and the display as a protective measure, so normal operation is not possible until the code is cleared. The fault is electronic rather than mechanical, so there is no immediate safety hazard, but the machine should not be forced to run in this state.

Manually clearing the code can resolve a d8 fault if it was triggered by a temporary power issue or a one-time data corruption event. However, if the underlying cause is a degraded EEPROM chip or a failing microprocessor on the UIC board, the code will return shortly after being cleared. Repeated return of the d8 code after resetting is a strong indicator that the UIC board needs to be replaced.

You can start by manually clearing the code, which resolves the fault if it was caused by a one-time power event or minor data corruption. If the code returns after clearing, the UIC board will likely need to be replaced, which is a moderately involved repair that requires disconnecting the control panel and swapping the board. A technician is recommended if you are not comfortable working with electronics.

If the fault clears permanently after a manual reset, there is no parts cost involved. If the UIC board needs replacement, parts alone typically range from $80 to $250 depending on the model, with professional labor adding $100 to $200 on top of that. Total repair costs generally fall in the range of $150 to $400 when serviced by a technician.
