Maytag Washer Error Code d22 F70

The d22 F70 code means the User Interface Control (UIC) is not receiving communication signals from the Central Control Unit (CCU). This communication failure causes the washer to disable cycle selection and the price display until the problem is resolved. It points to a fault somewhere in the communication path between the two control boards, including the wiring harness or the boards themselves.

Start by inspecting the wiring harness and connectors between the CCU and UIC for loose connections, damaged wires, or corrosion on the pins. Reseat any connectors that are not fully locked in place. If the wiring checks out, a technician will need to test each control board to determine which one has failed and requires replacement.

Repair costs depend on what component has failed. If the issue is a loose connector or damaged wire, costs may be minimal, typically covering just a service call fee in the range of $75 to $150. Replacing a CCU or UIC board generally adds parts costs in the range of $100 to $300 or more, depending on the specific part and labor rates in your area.

A manual reset may temporarily clear the d22 F70 code, but if the underlying cause is not corrected, the error will return. The error persists or reappears whenever the CCU fails to send communication signals to the UIC. A reset is useful for confirming whether the fault is intermittent, but it is not a permanent fix.

When the d22 F70 error is active, the washer disables cycle selection, which means it will not operate normally. Attempting to use the machine in this state is not recommended, as the control system is not functioning correctly. It is best to have the fault diagnosed and repaired before running any cycles.
