Miele Washer Error Code F4130

F4130 indicates a drive fault where contactor K1/9 inside the frequency converter has become charred and fused in the closed position. The frequency converter controls motor speed and power, and K1/9 is a switching relay within that circuit. When this relay overheats and fuses shut, the drive system can no longer safely operate. This is a hardware failure requiring physical inspection and component replacement.

No, you should not continue running the washer with this error active. A fused-closed contactor means the motor control circuit cannot safely interrupt power to the drive motor. Continued operation risks further electrical damage to the frequency converter and surrounding components, and poses a potential safety hazard.

Repair costs will vary depending on labor rates in your area and the extent of heat damage within the frequency converter. If only the K1/9 contactor needs replacement the cost will be lower, but if the surrounding converter circuitry or the motor itself sustained damage, costs rise significantly. Total repair estimates typically range from a few hundred dollars to upward of several hundred dollars for parts and labor combined.

This repair is not recommended for most homeowners. Accessing and replacing contactor K1/9 requires disassembling the machine to reach the frequency converter, working near high-voltage components, and correctly identifying the extent of heat damage. A qualified appliance technician with experience on Miele drive systems should perform this repair.

Resetting the machine will not resolve F4130. The fault is caused by a physically damaged and fused contactor, which is a hardware failure that a reset cannot address. The error will return immediately or prevent normal operation until the damaged K1/9 contactor is inspected and replaced.
