When your Bosch washing machine displays the E16 or F16 error code, it means the appliance has detected that the door is not securely closed. This safety feature prevents the washer from starting or continuing a cycle until the door lock is properly engaged. Although this issue can seem serious, it’s one of the most common Bosch washer problems and is usually simple to fix.
What the E16 / F16 Error Means
The E16 or F16 error appears when the control system senses that the washer door isn’t shut tightly enough to begin the wash. The error prevents the drum from spinning or filling with water, protecting you from leaks and mechanical damage. The problem can occur because the door wasn’t fully pushed in, an item is stuck in the seal, or the door latch or lock sensor is malfunctioning. Sometimes, the cause is electrical—such as a loose wire or damaged connector.
Common Causes of the E16 / F16 Error
One of the most frequent reasons for this error is a door that isn’t fully closed. Even a small obstruction, like a corner of a towel or a stray sock caught in the rubber seal, can prevent the latch from engaging. Another common culprit is a faulty door latch mechanism. Over time, wear and tear can stop the latch from clicking into place, meaning the control board never registers the door as closed.
In some cases, detergent residue or dirt buildup in the seal or around the latch can block proper closure. If the door appears misaligned, a loosened or bent hinge might be to blame. Less commonly, the issue lies within the washer’s wiring or control system—for instance, a damaged cable preventing power from reaching the lock.
How to Fix Bosch Error Code E16 / F16
Start by opening and firmly closing the washer door, listening for a clear click when it locks. If the error persists, check the door gasket and latch area for trapped clothing, lint, or detergent buildup. Clean the area with a damp cloth to ensure smooth closure. If the latch feels loose or doesn’t stay in place, it may require replacement.
You can also try performing a soft reset. Unplug the washing machine for five minutes to allow the system to discharge, then plug it back in and power it on. This can clear temporary electronic glitches affecting the door sensor. If you notice that the door seems uneven or doesn’t align perfectly with the frame, the hinge may need minor adjustment or tightening.
When these steps don’t work, the problem may be deeper—often involving the lock assembly or wiring. A technician can safely remove the door panel, test the continuity of the lock circuit, and replace any failed components.
When to Call a Technician
If your washer refuses to start even after cleaning, resetting, or checking the door alignment, professional help is recommended. Persistent E16 / F16 door lock errors, a visibly broken latch, or signs of electrical faults (such as a burnt smell or clicking sounds) all indicate that the system needs inspection. Certified Bosch repair technicians have the diagnostic tools and genuine replacement parts to restore safe and reliable operation.
Conclusion
The Bosch washing machine E16 / F16 error is essentially a door lock issue, preventing your washer from starting until it confirms that the door is securely closed. In most cases, the fix is as simple as cleaning the seal, checking for obstructions, or reseating the latch. However, if the error persists, scheduling a professional repair ensures the appliance remains safe, efficient, and ready for years of dependable service.
