Miele Dishwasher Error Code F01

The Miele dishwasher error code F01 signals a critical issue with the thermistor, an essential temperature sensor responsible for monitoring and controlling the dishwasher’s water temperature. Maintaining proper temperature—up to 65°C (149°F)—is crucial for thorough cleaning and sanitizing of your dishes.

What is the Thermistor and Why is It Important?

The thermistor acts as the dishwasher’s internal thermometer. It constantly measures water temperature and communicates with the control board to adjust heating elements. This precise temperature regulation ensures your dishwasher cleans efficiently, removing tough stains and killing bacteria for hygienic results.

Causes of Error Code F01

The F01 error occurs when the thermistor experiences a short circuit or suffers damage. This malfunction disrupts accurate temperature readings, causing the dishwasher to stop mid-cycle or fail to heat water properly. Common causes include:

• Thermistor failure due to wear or electrical faults

• Wiring damage or loose connections affecting sensor signals

• Moisture intrusion leading to sensor short-circuiting

How to Diagnose Error Code F01

To troubleshoot, carefully access the thermistor component inside your Miele dishwasher. Using a multimeter, measure the thermistor’s resistance:

• A normal thermistor typically shows a specific resistance value depending on temperature.

• A reading of zero (0 Ω) or no reading at all indicates a short circuit or open circuit.

If the thermistor fails this test, replacement is necessary.

Effective Repair Solutions

Replacing the faulty thermistor with an original, compatible Miele part is the best way to restore your dishwasher’s performance. This repair ensures:

• Accurate temperature sensing for optimal wash cycles

• Reliable heating element control

• Prevention of recurring error codes and dishwasher downtime

Why Timely Repair Matters

Ignoring the F01 error risks damaging other components and compromises your dishwasher’s cleaning ability. Promptly addressing the thermistor issue safeguards your appliance’s lifespan and maintains the high cleaning standards expected from Miele.
