Step-by-Step DIY Fix Guide
- SAFETY: No power disconnect needed unless inspecting the latch mechanism.
- Open the door and check that no item of clothing is caught between the door and the rubber seal — remove any found.
- Check that the drum is not overloaded — laundry should not protrude above the drum opening.
- Redistribute or remove some laundry if the drum is overfull.
- Close the door firmly until you hear an audible click.
- Press Start/Pause to restart the program.
- If E16 returns, inspect the door latch hook for visible wear or damage.
- Check the rubber door seal for tears or debris sitting proud of the seal channel.
If the warning comes back after restart
- If the door closes normally but the warning keeps returning, the latch or switch path becomes more likely than a simple alignment issue.
- If airflow still seems weak after the basic checks, the fan path or a deeper obstruction becomes more likely.
- If the warning returns immediately after a clean restart, the sensor or wiring path becomes more likely than a one-time glitch.
What This Error Means
E16 on your Bosch washing machine means: The washing machine door is not fully closed and locked. The machine will not start, or has stopped mid-cycle because the door lock cannot be confirmed. The machine detects this condition via its sensors and stops the current cycle to prevent further damage. The error will remain until the underlying cause is resolved.
The most frequent cause is clothing or fabric caught between door and rubber door seal. Work through the causes listed below in order — the first cause is the most likely and the most straightforward to check.
Error E16 is DIY-safe for most homeowners. The fix typically takes under 30 minutes and requires no specialist tools. Follow the steps below exactly — skipping steps is the most common reason the error returns.
The machine will not start or will pause mid-cycle when the door lock cannot be confirmed. Check for clothing caught in the door seal before assuming a mechanical fault — this is the cause in the majority of cases.
Most Likely Cause by Symptom
The Bosch washing machine may stop, pause, or refuse to complete the cycle normally.
Likely cause: Clothing or fabric caught between door and rubber door seal
Check first: SAFETY: No power disconnect needed unless inspecting the latch mechanism.
The appliance may fail to start because the door or lock state cannot be confirmed.
Likely cause: Overloaded drum preventing door from closing fully
Check first: Open the door and check that no item of clothing is caught between the door and the rubber seal — remove any found.
The warning may return immediately because the appliance is detecting an internal fault.
Likely cause: Worn or damaged door latch hook
Check first: Check that the drum is not overloaded — laundry should not protrude above the drum opening.
Common Causes
- Clothing or fabric caught between door and rubber door seal
- Overloaded drum preventing door from closing fully
- Worn or damaged door latch hook
- Door hinge misalignment after machine was moved
- Failed door interlock (lock solenoid) not engaging
What Not to Do
- Do not force the door closed if laundry is blocking it — fabric damage and seal tears result
