Maytag Washer Error Code d22

The d22 code indicates a communication failure between the dryer CCU (Central Control Unit) and the UIC (User Interface Control). The UIC is not receiving signals from the CCU, which causes the unit to disable cycle selection and the price display. The error persists until the underlying issue is resolved or the code is manually cleared.

The d22 error can be manually cleared, but it will return if the underlying communication failure is not repaired. Simply cycling power or resetting the unit without addressing the wiring or board fault will not provide a lasting fix. Clearing the code is only useful as a step in confirming whether the repair resolved the issue.

Repair costs vary depending on the cause. If the fix involves re-seating a connector or cleaning corrosion, there may be little to no parts cost, though a service call from a technician typically runs between $75 and $150. If a control board replacement is needed, parts alone can range from $100 to $350 or more depending on the specific board, with labor adding to the total.

If you are comfortable working with appliance wiring, you can check the harness connectors between the CCU and UIC for looseness, corrosion, or visible wire damage without specialized tools. Re-seating connectors and cleaning corroded pins are tasks many experienced DIYers can handle. However, if the fault lies with a control board, replacement requires identifying the correct part and basic electronics handling skills.

When d22 is active, the unit disables cycle selection and the price display, which means normal operation is not possible in this state. Attempting to operate the unit without these functions could lead to incomplete or improper cycles. It is best to resolve the communication fault before running laundry loads.
