Symptom / Description

FAULT

Faure FWG / FWF Series / Magic'45 Compact Washer: Electronic pressure sensor frequency out of range E31; sensor output signal < 32 Hz or > 46 Hz.

TELEMETRY // LIVESIG: FAULT_DETECTED

Root Cause

ROOT CAUSE

On Faure (Faure FWG / FWF Series / Magic'45 Compact Washer) models: Defective internal oscillator in electronic pressure sensor, damaged diaphragm, open circuit on 5V DC/GND/Signal wires, or faulty MCU input pin.

CIRCUIT // SUBSYSTEMLOGIC: ROOT_ISOLATED

Repair Instructions

UNLOCKED

1Use multimeter frequency mode (Hz) to measure signal on center pin (nominal empty frequency ~43.5 Hz). Replace electronic pressure switch if static frequency is out of 42–45 Hz range. Press and hold Départ/Pause and Annulation buttons for 6 seconds until all status indicators flash synchronously and clear fault memory.

1. Pre-Intervention Electrical Safety Protocols

!Electrical Safety Protocol: Cut 230V mains power before accessing the upper chassis or pressure switch terminals.
!Drain appliance tub completely before disconnecting pressure switch sensing hoses.
!Never blow high-pressure compressed air into electronic analog pressure sensors: internal diaphragms will rupture!

3. Preliminary Mechanical & Visual Checks

Disconnect the silicone pressure tube from the lower air trap and inspect for soap sludge, lint, or water blockage.
Inspect the flexible rubber hose along its entire length for pinholes, cracks, or loose clamp fit.
Thoroughly flush the lower compression chamber (air dome) with hot water to dissolve detergent buildup.

Frequently Asked Questions: Faure E31

FAQ TREE

What does error code E31 mean on a Faure appliance?

Faure error code E31 indicates: Faure FWG / FWF Series / Magic'45 Compact Washer: Electronic pressure sensor frequency out of range E31; sensor output signal < 32 Hz or > 46 Hz..

What is the root cause of Faure error code E31?

The primary root cause for Faure code E31 is: On Faure (Faure FWG / FWF Series / Magic'45 Compact Washer) models: Defective internal oscillator in electronic pressure sensor, damaged diaphragm, open circuit on 5V DC/GND/Signal wires, or faulty MCU input pin..

How do I fix or resolve Faure error code E31?

To resolve error code E31: Use multimeter frequency mode (Hz) to measure signal on center pin (nominal empty frequency ~43.5 Hz). Replace electronic pressure switch if static frequency is out of 42–45 Hz range. Press and hold Départ/Pause and Annulation buttons for 6 seconds until all status indicators flash synchronously and clear fault memory.

Is it safe to clear Faure error code E31 by resetting power?

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Faure code E31 persists, the physical component causing On Faure (Faure FWG / FWF Series / Magic'45 Compact Washer) models: Defective internal oscillator in electronic pressure sensor, damaged diaphragm, open circuit on 5V DC/GND/Signal wires, or faulty MCU input pin. must be inspected or replaced.

How do I test electrical resistance for Faure code E31 using a multimeter?

Set a digital multimeter to ohms (Ω). Disconnect power and test Mechanical Pressure Switch Contacts / Inductive Frequency Sensor across Across switch spade contacts with harness unplugged; electronic output: 40Hz–50Hz frequency signal. Expected nominal reading is Mechanical: Continuity 0.0Ω–0.2Ω (Empty: 11-12, Full: 11-14). Electronic: 20Ω–45Ω coil resistance.. Tolerance: Mechanical switch contacts must transition cleanly on gentle breath pressure. Coil ~22Ω ±5%..

What safety protocol must be followed before servicing Faure code E31?

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.
