What Does Error Code E16 Mean on a Siemens Washing Machine?
Firmly push the door until you hear a distinct click, then press Start — if the door latch was simply unlatched, the machine should clear the error and begin the cycle immediately (takes about 2 minutes).
Fault description
Error code E16 is the Siemens washing machine's way of telling you it cannot confirm the door is securely closed. Before any wash cycle can begin — or continue — the control board must receive a signal from the door lock assembly confirming the door is shut and locked. If that signal is absent or interrupted, the machine stops and displays E16 to prevent water from leaking out of an unsecured door.
When E16 appears, the drum will not rotate and the machine will not fill with water. In some cases the error shows mid-cycle, which can leave laundry sitting in water until the fault is resolved. The good news is that the most common cause is straightforward: the door simply was not pushed shut with enough force, or a small item of clothing is caught in the door seal.
Causes
- Door not fully closed — The most frequent reason for E16 is that the door was not pushed firmly enough to engage the latch. A small garment, sock, or piece of fabric caught between the door and the rubber seal can also prevent a proper seal.
- Worn or broken door latch — The plastic latch hook on the door itself can wear down or snap over time, meaning it no longer engages the lock mechanism even when the door appears closed. This is more common on machines that are several years old.
- Faulty door lock assembly (interlock) — The door lock assembly contains an electromechanical interlock that physically secures the door and sends a confirmation signal to the control board. If the interlock fails electrically or mechanically, the board never receives confirmation and E16 is triggered.
- Damaged or obstructed door hinge — A bent or loose door hinge can cause the door to sit slightly out of alignment, preventing the latch from reaching the lock correctly. Visible sagging of the door when open is a sign of a hinge problem.
- Wiring fault between door lock and control board — The wiring harness connecting the door lock assembly to the main control board can develop a loose connector or a broken wire, interrupting the signal even when the lock itself is functioning. This is less common but worth checking if the lock appears physically intact.
- Control board fault — In rare cases the main control board fails to correctly read the signal from a working door lock, causing a false E16 error. This is typically a last-resort diagnosis after all other causes have been ruled out.
Step-by-Step Fix
- 1
Check for trapped laundry in the door seal
Open the door and run your hand around the entire rubber door gasket, feeling for any fabric caught between the seal and the drum rim or the door glass. Even a thin sock can break the seal enough to prevent the latch from engaging. Remove any obstruction, then close the door firmly.
- 2
Close the door with firm, deliberate pressure
Stand directly in front of the machine and push the door closed with the heel of your hand until you hear and feel a clear click. Avoid pushing only on the door handle or the edge — apply pressure to the centre of the door. Once closed, press Start to see if the error clears.
- 3
Power cycle the machine
Turn the programme dial to the off position, switch the machine off at the wall socket, and wait 60 seconds before switching it back on. Select your programme and attempt to start a cycle. A brief power reset can clear a temporary control board glitch that caused a false E16 reading.

Inspect the door latch hook for damage
With the door open, examine the plastic latch hook on the door itself — it is the protruding tongue that slots into the lock on the machine body. Look for cracks, chips, or a rounded-off tip. If the hook looks worn or broken, it will need to be replaced; this is a relatively inexpensive part available for most Siemens models.
- 5
Check the door hinge alignment
Open the door fully and observe whether it droops or sits unevenly compared to the machine body. Gently lift the door by its outer edge — if there is noticeable play or movement at the hinge, the hinge may be loose or bent. Tighten any accessible hinge screws with a Torx or Phillips screwdriver and retest.
- 6
Inspect the door lock assembly wiring
Unplug the machine from the mains before proceeding. Remove the door seal and the front panel trim to access the door lock assembly (consult your model's service diagram if needed). Check that the wiring connector is firmly seated on the lock. A loose connector can be reseated by hand; a visibly damaged wire will need professional repair.
- 7
Test or replace the door lock assembly
If all previous steps have not resolved the fault, the door lock interlock itself is the most likely culprit. With the machine unplugged, remove the lock assembly and use a multimeter to test continuity across its terminals according to the expected values for your model. A failed interlock should be replaced with a compatible Siemens part.

When to call a service technician
If you have worked through all the steps above — confirmed no trapped laundry, checked the latch and hinge, reseated the wiring connector, and the error still appears — it is time to contact a service technician. A failed door lock interlock or a wiring fault deeper in the harness requires proper diagnostic tools and safe handling of electrical components.
You should also call a technician immediately if the door feels physically jammed and will not open at all, if you can see burn marks or smell burning near the door lock area, or if the machine is still under warranty and you do not want to risk voiding it by disassembling the front panel yourself.

Frequently Asked Questions
Can I still use my Siemens washing machine if it keeps showing E16?
No — the machine will not run a cycle while E16 is active because it cannot confirm the door is safely locked. Attempting to force a cycle is not possible and the machine is designed this way to prevent flooding. Resolve the door fault first before using the appliance.
How do I open the door if E16 appeared mid-cycle and the door is locked?
First, turn the machine off and wait two to three minutes — the door lock has a thermal release that should disengage once power is removed. If the door still will not open, most Siemens machines have an emergency release cord located behind the kick panel at the bottom front of the machine. Pull it gently to manually release the lock.
How much does a Siemens door lock assembly cost to replace?
A replacement door lock interlock for a Siemens washing machine typically costs between £15 and £40 for the part, depending on the model. If you are comfortable with basic appliance repair, fitting it yourself is straightforward. A service technician call-out will add labour costs on top of the part price.
Why did E16 appear suddenly when the machine was working fine before?
Door lock interlocks can fail without warning as the internal components wear out over years of use. It is also possible that a small item of laundry became trapped in the seal for the first time, or that a wiring connector worked loose due to vibration over many cycles. Check the simple causes first before assuming a component has failed.
Is E16 the same as an F16 error on Siemens machines?
On most Siemens washing machine ranges, E16 and F16 refer to the same door lock fault — some display panels show an 'E' prefix while others show 'F', but the underlying meaning and the troubleshooting steps are identical. Check your model's manual if you are unsure which code applies to your specific machine.
