What E206 Means
E206 records that the lower cavity of a Bosch double wall oven failed to lock its door. The control asks for the latch, waits a minute, and stops trying. Bosch notes that the error cancels and normal operation resumes when a locked door is no longer required, which is why this usually surfaces at the start of a self-clean on the lower oven and then disappears.
Common Causes of E206
- Debris or carbon build-up stopping the lower door closing fully
- Latch motor or switch on the lower cavity failed
- Wiring fault between the shared control module and the lower latch
🔧 One Safe Check You Can Try
Clean the lower door gasket and the latch recess of baked-on residue, and check the door closes square against the frame. Lower cavities collect more spillage than upper ones, so debris in the latch path is a genuinely common cause here.
⚠ Why You Shouldn't Go Further Than That
- Bosch works through latch motor, switch, wiring and door switch in order, and those live behind the fascia of a stacked appliance.
- Forcing a latch that will not engage bends the strike plate, after which the lower door will not seal properly for ordinary baking either.
- The lower cavity of a double oven is the one people use for long roasts, so a door that does not seal costs more than a failed clean cycle.
- Self-clean should not be used as a test for a latch that has already failed to engage once.
