Maytag Washer Error Code E313

E313 is an Option Fault code indicating that the frequency inverter, which controls motor speed, is not receiving serial communication requests from the washer's main control board. This breakdown in communication prevents the washer from properly executing wash and spin cycles. The fault points to a problem in the communication link between these two components, which could involve wiring, the inverter itself, or the control board.

A reset may temporarily clear the E313 code, but if the underlying communication fault between the control board and the frequency inverter is still present, the error will return when the washer attempts to run a cycle. A reset is not a fix. The root cause, whether it is a wiring issue, a faulty contactor, or a failed component, must be identified and corrected for the error to stay cleared.

Repair costs vary depending on which component is at fault. Wiring harness repairs or connector replacements tend to be on the lower end, typically ranging from around $75 to $200 including labor. Replacing a frequency inverter or main control board is more expensive, with parts and labor costs often ranging from $200 to $500 or more depending on the specific model and local labor rates. Getting a diagnostic inspection first will help identify the exact failed component before committing to a repair.

Some basic checks, like inspecting wiring connectors between the control board and inverter for looseness or corrosion, can be performed by a knowledgeable DIYer. However, diagnosing the power supply contactor behavior across all phases and testing the frequency inverter requires electrical knowledge and appropriate test equipment. If you are not comfortable working with high-voltage components, a qualified appliance technician should perform the diagnosis and repair.

Running the washer with an active E313 fault is not recommended. Because the motor speed controller is not receiving commands from the main control board, the machine cannot operate its cycles correctly. Attempting to run cycles in this condition could cause incomplete wash cycles or place additional stress on electrical components. The washer should be serviced before regular use resumes.
