Whirlpool Washer Error Code d22

The d22 code is the AccuTrac display equivalent of error code F70, indicating a Central Control Unit heartbeat failure. It means the CCU and the User Interface board have lost communication with each other. The washer will not operate until this communication link is restored. The problem can originate in the wiring harness connecting the two boards or in either of the boards themselves.

A power reset, such as unplugging the washer for a few minutes and restarting it, may temporarily clear the code if the communication failure was caused by a transient power glitch. However, if the underlying cause is a damaged harness, a loose connector, or a failed control board, the error will return as soon as the washer attempts to operate. A reset is not a repair and should only be used as a diagnostic step.

Repair costs depend on the root cause. If the issue is a damaged wiring harness, parts and labor typically range from around $75 to $200. Replacing the User Interface board generally costs between $150 and $350 including labor. Replacing the Central Control Unit is the most expensive scenario, often ranging from $200 to $500 or more depending on the specific model and labor rates in your area.

A knowledgeable DIYer can address this error by first checking the User Interface wiring harness for continuity and inspecting all harness connectors for loose or corroded connections. If the harness is intact, resolving the issue will require replacing either the UI board or the CCU, which involves working with electronic components and internal wiring. If you are not comfortable working inside the appliance, a qualified technician should perform the repair.

No. When the d22 code is active, the washer has detected a control communication failure and will not operate normally. Attempting to force operation while this fault is present is not recommended, as the machine cannot properly coordinate its components without reliable communication between the CCU and UI board. Leave the washer unplugged until the issue is diagnosed and resolved.
