Miele Washer Error Code F4013

F4013 means the frequency converter's intermediate circuit voltage has dropped too low, cutting power to the drive motor. The frequency converter is the electronic module that controls motor speed and torque. When its internal DC bus voltage is insufficient, the motor cannot operate and the washer will stop or fail to start a cycle. The fault points to an issue in the power supply chain feeding the converter or within the converter module itself.

No, the machine should not be used while this fault is active. F4013 indicates the drive motor is not receiving proper power, which means the washer will not complete cycles reliably. Continuing to attempt operation could stress other electrical components. Unplug the machine until the fault has been properly diagnosed and resolved.

A reset may temporarily clear the fault code, but F4013 will return if the underlying cause has not been corrected. Because this fault involves insufficient voltage in a critical power circuit, resetting without repair does not fix the problem and may not even allow a full cycle to complete. A proper diagnosis of the power supply, wiring, and frequency converter is necessary for a lasting resolution.

Some basic checks, such as verifying the outlet voltage is correct and inspecting accessible wiring connectors for looseness or corrosion, can be performed by a knowledgeable DIYer. However, diagnosing and replacing the frequency converter or power board involves working with high-voltage components and requires disassembling the machine. For most homeowners, this repair is best handled by a qualified appliance technician.

Repair costs depend on the root cause. If the fix is limited to a wiring connection, costs could be in the range of a standard service call fee, typically $100 to $200. If the frequency converter module requires replacement, parts alone for a Miele appliance can range from $200 to $500 or more, with total repair costs including labor potentially reaching $350 to $700. Getting a diagnostic estimate before approving parts replacement is advisable.
