Miele Washer Error Code F4261

F4261 means the washer's control system is not receiving a valid speed signal from tachogenerator G1 on the motor. The tachogenerator produces electrical pulses as the motor spins, and the controller uses these pulses to monitor drum speed. When those pulses are missing or detected as faulty, the machine triggers F4261 and stops operation. The fault can originate from the tachogenerator itself, the wiring harness, the motor, or the control board.

The washer should not be operated while F4261 is active. Without a valid motor speed signal, the control system cannot regulate the drum correctly, which could lead to further damage to the motor or control electronics. Stop using the machine until the fault is diagnosed and repaired.

Resetting the washer by powering it off and back on may temporarily clear the displayed error, but F4261 will return if the underlying fault is still present. A reset does not repair a failed tachogenerator, broken wiring, or faulty control board. The root cause must be identified and corrected to permanently resolve the fault.

Some causes of F4261 are approachable for a confident DIYer, such as inspecting and reseating wiring connectors or checking for obvious harness damage. However, testing the tachogenerator coil resistance, diagnosing the motor, or replacing the control board requires comfort with electrical testing and disassembling the appliance. If you are not experienced with appliance electrical work, a qualified technician is recommended.

Repair costs vary depending on the root cause. Wiring repairs or connector cleaning may involve only a service call fee, typically in the range of $100 to $200. A replacement tachogenerator or motor will add parts costs on top of labor, potentially bringing the total to $200 to $600 or more depending on the specific component needed and local labor rates.
