Check the customer’s voltage while powering the unit on and trying to run a cycle.

If voltage measured at the wall has a drop of 10% or more than the rated voltage when powering up, then the customer’s electrical system is the cause. (Example: If you measure 120V with the unit powered off and it drops to 108V or less when powered on, then there is an electrical issue on the home side that needs to be addressed).

If voltage measured is too high, higher than 10% over the rated voltage, it may also trigger this error code.

The customer will need an electrician to repair their receptacle, breaker or electrical wires in their home.
