Scholtès Tumble Dryer F23

Scholtès error code F23 indicates: Scholtès Heat Pump Sensor Dry Tumble Dryer: Lower condenser filter blockage warning F23; differential pressure switch or temperature delta detects restricted air path..

The primary root cause for Scholtès code F23 is: On Scholtès tumble dryers: Compressed sponge filter saturated with damp lint in bottom plinth compartment, or warped filter frame allowing air bypass..

To resolve error code F23: Open plinth door, pull out foam filter element, wash thoroughly under running water, squeeze dry with towel, and reinstall firmly into cassette housing. Switch selector to Stop, press and hold Start/Pause for 5 seconds to clear error memory, then power off for 1 minute.

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Scholtès code F23 persists, the physical component causing On Scholtès tumble dryers: Compressed sponge filter saturated with damp lint in bottom plinth compartment, or warped filter frame allowing air bypass. must be inspected or replaced.

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%..

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.
