Bosch F16

Bosch error code F16 indicates: Bosch Serie 4 / Serie 6 / Serie 8 / HomeProfessional EcoSilence Drive: Door interlock open fault F16; appliance cannot start wash program because door latch contacts remain unmade..

The primary root cause for Bosch code F16 is: On Bosch washers: Laundry trapped between door glass and rubber bellows, worn mechanical latch strike hook, or open circuit in PTC door lock coil..

To resolve error code F16: Press door firmly until it clicks. Inspect door hook for mechanical damage. Measure resistance across door lock terminals 1 and 3 (nominal ~180–240 Ω). 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 F16 persists, the physical component causing On Bosch washers: Laundry trapped between door glass and rubber bellows, worn mechanical latch strike hook, or open circuit in PTC door lock coil. must be inspected or replaced.

Set a digital multimeter to ohms (Ω). Disconnect power and test PTC Heater Pellet / Pulse Solenoid / Microswitch Contacts across Across PTC heater terminals on lock bezel; switch contact reads <0.2Ω when locked. Expected nominal reading is 800Ω–1.5kΩ (PTC terminals L-N) / 60Ω–120Ω (Pulse Solenoid). Tolerance: ±15%. Switch contacts must read open (OL) when unlocked and 0.0Ω–0.2Ω when fully latched..

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.
