What the F01 error code actually means

Your Bosch dishwasher is displaying F01 because the water temperature sensor is sending a faulty signal, likely due to a short circuit in the sensor itself or the wires connected to it. The dishwasher uses this sensor to monitor water temperature during washing and drying, and when it detects a problem, it stops the cycle to protect the appliance. A technician will need to test the sensor and its wiring to determine whether the sensor or the wiring needs to be replaced.

Questions people ask about F01

What does F01 mean on a Bosch dishwasher?
F01 on a Bosch dishwasher indicates that the Water/Heating NTC temperature sensor or its wiring leads have a short circuit. The control board monitors the resistance of this sensor to track water temperature, and a short causes the reading to fall outside the acceptable range. The dishwasher will not operate normally until the fault is resolved.
Is it safe to use my Bosch dishwasher when F01 is displayed?
It is not recommended to continue running the dishwasher while F01 is active. The temperature sensor is a critical safety component that prevents the water from overheating during wash and dry cycles. Without a reliable temperature reading, the appliance cannot regulate heat properly, which could result in damage to dishes, the appliance itself, or in extreme cases, a safety hazard.
Will resetting my Bosch dishwasher clear the F01 error code?
A reset may temporarily clear the F01 code, but the error will return if the underlying short circuit in the sensor or wiring has not been repaired. Resetting is useful as a first step to confirm whether the fault is intermittent or persistent, but it does not fix the root cause. The sensor circuit must be tested and any faulty components replaced for a lasting resolution.
Can I fix the F01 error on my Bosch dishwasher myself?
A knowledgeable DIYer can start by checking the sensor plug connections, reseating any loose connectors, and inspecting the wiring harness for visible damage. Testing the NTC sensor requires a multimeter: at 68 degrees F, the sensor should read approximately 14.9 kOhm plus or minus 600 Ohms. If the sensor or wiring is faulty, replacing the component is straightforward but does require disconnecting the appliance from power and accessing internal components.
How much does it cost to repair a Bosch dishwasher F01 error?
If only the wiring connections need to be cleaned or reseated, there may be no parts cost involved. Replacing the NTC temperature sensor typically costs between $20 and $60 for the part, depending on the specific model. If a technician is hired for diagnosis and repair, total costs including labor generally range from $100 to $250.
