Bosch F23

Bosch error code F23 indicates: Bosch Serie 4 / Serie 6 / Serie 8 / HomeProfessional EcoSilence Drive: AquaStop base float switch activated F23; water leak detected in bottom pan, safety drain pump runs continuously..

The primary root cause for Bosch code F23 is: On Bosch washers: Water leak from cracked tub bellows gasket, loose hose clamp on drain pump, split inlet dispenser hose, or tub seam leak..

To resolve error code F23: Disconnect mains. Tilt washer backwards 45° to drain base tray and drop float switch. Locate water leak source and replace ruptured hose/gasket. Turn dial to 6 o'clock (down), hold Spin button, rotate to 7 o'clock, release Spin button, turn to 12 o'clock (Off).

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Bosch code F23 persists, the physical component causing On Bosch washers: Water leak from cracked tub bellows gasket, loose hose clamp on drain pump, split inlet dispenser hose, or tub seam leak. must be inspected or replaced.

Set a digital multimeter to ohms (Ω). Disconnect power and test Drain Pump Motor Stator Coils across Across pump motor spade terminals (L-N unclipped). Expected nominal reading is 160Ω–220Ω (Sync 230V) / 20Ω–45Ω (3-Phase BLDC). Tolerance: ±10% balance. Insulation resistance between coil and motor chassis must exceed 20MΩ..

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.
