Miele Dishwasher Error Code F02

Miele dishwashers are known for their reliability and advanced technology, but even the best appliances can encounter issues. One common problem is the Error Code F02, which indicates a fault with the thermistor sensor — specifically, an open circuit caused by disconnected or loose wiring.

What Does Error Code F02 Mean?

Error F02 signals that the thermistor, a crucial temperature sensor in your dishwasher, has an open circuit. This means the electrical connection is interrupted, often due to loose or disconnected cables, preventing the dishwasher from accurately monitoring and regulating temperature.

How to Fix Miele Dishwasher Error Code F02

Step 1: Check and Reconnect Cable Harnesses

Open the dishwasher panel and carefully inspect the heating element’s wiring and cable harnesses. Loose or disconnected cables are the most common cause of the F02 error. Securely reconnect any loose wires to restore proper electrical continuity.

Step 2: Inspect the Thermistor Sensor

If reconnecting the cables doesn’t solve the problem, the thermistor sensor itself might be faulty or damaged. It’s advisable to test the thermistor for continuity with a multimeter. In some cases, replacing the thermistor may be necessary for a permanent fix.

Step 3: Refer to Related Errors

Because F02 is related to thermistor faults like F01, reviewing troubleshooting steps for Error Code F01 can provide additional insights and solutions to ensure your dishwasher operates smoothly.

When to Call a Professional

If you are not comfortable inspecting electrical components or if the error persists after these steps, contact a qualified appliance technician. Proper diagnosis and repair by a professional can save time and prevent further damage.
