Miele Dishwasher Error Code F2

F2 on a Miele dishwasher indicates that the NTC temperature sensor leads or temperature control components have a short circuit condition. The control board detected abnormally low resistance in the sensor circuit, which prevents accurate water temperature monitoring. As a result, the dishwasher halts operation to avoid running a cycle with uncontrolled temperatures.

No. The F2 fault means the dishwasher cannot properly monitor water temperature, which is a core safety and performance function. Running the machine in this condition could result in overheated water or incomplete wash cycles. The dishwasher should remain out of service until the short circuit is identified and corrected.

Repair costs depend on which component has failed. NTC sensor replacement is generally the least expensive fix, with parts and labor typically ranging from around $80 to $200. If the control board is at fault, costs can range from $200 to $500 or more depending on parts availability and labor rates in your area.

A knowledgeable DIYer can inspect the NTC sensor wiring harness for visible damage, check connector terminals for corrosion, and test the sensor resistance with a multimeter. If the sensor reads near-zero ohms regardless of temperature, it needs replacement. However, if the wiring and sensor test normal, the control board may be at fault, which typically requires a qualified technician to diagnose and replace.

A power reset may temporarily clear the fault display, but if the underlying short circuit in the NTC sensor circuit is still present, the F2 code will return as soon as the dishwasher attempts to read temperature. The root cause must be repaired for the error to clear permanently.
