Repair Instructions

UNLOCKED

1Check rear duct probe resistance (~10 kΩ–20 kΩ at 25°C). Inspect sensor lead routing to ensure no heat damage from rear element. Set program dial to 12 o'clock (Off), press and hold Start and Delicate buttons for 5 seconds until double tone sounds, then release.

1. Pre-Intervention Electrical Safety Protocols

!Electrical Safety Protocol: Disconnect 230V electrical mains power before removing appliance side or rear panels.
!Ensure tub water or heating chamber has cooled below 30°C before unclipping thermistor probe.
!Use CAT III 600V/1000V insulated test probes when tng at PCB edge connectors.

3. Preliminary Mechanical & Visual Checks

Inspect sensor immersion sleeve for calcification, limescale scale, or thermal paste degradation.
Check wiring harness for pinch points, chafing against chassis metal, and terminal pin oxidation.
Verify probe is firmly seated in its rubber grommet or bracket inside the water/air circuit.

FAQ TREE

What does error code F2 mean on a Rosieres appliance?

Rosieres error code F2 indicates: Rosières RLE Heat-Pump Tumble Dryer: Rear exhaust temperature sensor fault F2; exhaust air probe sends corrupted or out-of-range temperature signal..

What is the root cause of Rosieres error code F2?

The primary root cause for Rosieres code F2 is: On Rosières dryers utilizing RLE thermodynamic heat-pump condensation circuit, precision electronic moisture sensor, and low-vibration chassis: Defective rear duct NTC thermistor, damaged sensor wire harness near heater chamber, or connector corrosion..

How do I fix or resolve Rosieres error code F2?

To resolve error code F2: Check rear duct probe resistance (~10 kΩ–20 kΩ at 25°C). Inspect sensor lead routing to ensure no heat damage from rear element. Set program dial to 12 o'clock (Off), press and hold Start and Delicate buttons for 5 seconds until double tone sounds, then release.

Is it safe to clear Rosieres error code F2 by resetting power?

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Rosieres code F2 persists, the physical component causing On Rosières dryers utilizing RLE thermodynamic heat-pump condensation circuit, precision electronic moisture sensor, and low-vibration chassis: Defective rear duct NTC thermistor, damaged sensor wire harness near heater chamber, or connector corrosion. must be inspected or replaced.

How do I test electrical resistance for Rosieres code F2 using a multimeter?

Set a digital multimeter to ohms (Ω). Disconnect power and test NTC Temperature Sensor Probe (Thermistor) across Across sensor pins 1-2 (unplugged harness). Expected nominal reading is 4.8kΩ–12kΩ (at 20°C–25°C). Tolerance: Negative temperature coefficient: resistance drops smoothly when warmed with fingers. OL = open circuit..

What safety protocol must be followed before servicing Rosieres code F2?

Standard electrical safety protocol: 1. Disconnect 230V mains power before opening panels. 2. Verify zero voltage at test points. 3. Allow hot water or heating elements to cool below 30°C before handling.
