Oven door remains locked after pyrolytic cycle or power cut; E09 is displayed and the door cannot be opened normally.

Safety first: Turn off power and allow the oven to cool completely. Do not force the door open with excessive strength, as this can damage the glass and hinges.

Manual release and checks:

• Remove the oven from the cabinet enough to access the top or front where the lock assembly is located.
• Look for a manual release lever or tab on the lock assembly (many Teka pyrolytic models include this). Move it gently to the unlock position while lightly pulling the door.
• Once the door is open, inspect the latch and lock mechanism for deformation or heat damage.
• Test the lock microswitches with a multimeter to ensure they change state between locked and unlocked positions.
• If the lock is stiff or melted, replace the entire door lock assembly.
• Check wiring continuity from the lock switches back to the control board; repair any broken or burned wires.

Reset: After repair, restore power and reset the oven (consult the user manual for your model). Run a short test of the lock function by starting and canceling a pyrolytic cycle to ensure proper operation.
