Dryer displays E09 and stops; may occur shortly after starting a cycle.

Safety first: Disconnect mains power before cleaning internal sensor contacts.

• Locate moisture sensors: On many Montpellier dryers, two metal strips are located inside the drum near the lint filter opening.
• Clean sensor bars: Using a soft cloth and white vinegar or mild detergent, thoroughly clean the metal strips to remove fabric softener residue and lint. Dry completely.
• Check for damage: Inspect the bars for deep scratches or corrosion. If damaged, they may need replacement.
• Inspect wiring (if accessible): From the front or rear (depending on model), locate the sensor wiring and ensure connectors are secure.
• Test operation: Restore power and run an automatic program with a damp load. If E09 reappears, the sensor circuit on the PCB may be faulty and require professional repair.
