What E106 Means
E106 is logged when the oven asks the door latch to lock and cannot confirm that it did. Bosch gives the timing: the latch fails to lock within one minute and further attempts stop. The error is cancelled and normal operation resumes if a locked door is no longer needed, which is why it often appears when a self-clean cycle is started and then abandons itself.
Common Causes of E106
- Latch motor or its switch failed
- Obstruction preventing the door closing fully square
- Wiring fault between the control board and the latch assembly
🔧 One Safe Check You Can Try
Check the door gasket and the latch recess for baked-on debris that stops the door pulling fully home, and confirm nothing on the racks is holding the door a millimetre open. A door that cannot close square is a door the latch cannot engage.
⚠ Why You Shouldn't Go Further Than That
- The latch assembly lives in the top of the oven frame behind the control panel, reached by pulling the appliance out and taking the front apart.
- Bosch's check sequence covers the latch motor, its switch, the wiring and the door switch, and each is eliminated in turn rather than replaced on a hunch.
- A latch forced by hand bends the strike plate, after which the door neither locks nor seals correctly.
- Self-clean depends on this latch working, so an oven that cannot lock should not be put through a clean cycle to test it.
Opening a panel to inspect or repair something yourself doesn't automatically cancel your manufacturer's warranty — but it can risk accidental damage, and some manufacturers do have specific service conditions. Check your product's warranty terms, or ask us, before deciding.
