Miele Washer Error Code F4106

F4106 indicates a checksum fault for the monitoring program allocation list stored inside the washer's main control unit. The control board verifies stored data using a checksum calculation, and this fault appears when that verification fails. It points to a data corruption issue within the control unit's internal memory. Professional diagnosis is typically required to resolve it.

It is not recommended to continue running the washer with an active F4106 fault. Since the monitoring program allocation list governs how the control unit supervises wash cycles, a corrupted list could result in unpredictable machine behavior. Discontinue use until the fault has been diagnosed and resolved.

Repair costs for F4106 will vary depending on whether the control board can be repaired or must be replaced, along with local labor rates. Control board replacement on a Miele washer typically falls in the range of $300 to $700 or more, including parts and labor. Getting a diagnostic assessment from a Miele-authorized technician is the best first step to confirm the cause and receive an accurate estimate.

Because F4106 originates inside the main control board's memory, there is limited troubleshooting that can be done without specialized diagnostic equipment. A hard reset by unplugging the washer for several minutes is worth attempting, but if the fault returns, control board replacement is likely necessary. This repair is best handled by a qualified appliance technician.

A power reset by unplugging the machine for a few minutes may temporarily clear the fault code. However, if the control board's memory is genuinely corrupted, the F4106 error will return once the board attempts to verify the program allocation list again. A persistent F4106 fault requires hardware-level diagnosis, not just a reset.
