What E226 Means
E226 means the control has lost the position signal from the lower cavity's door latch switch on a Bosch double wall oven. Because it can no longer tell whether that door is locked or unlocked, Bosch disables all heating elements, and the manual states the error can only be cleared by a software reset. The checks named are the switch connections, the wiring back to the control module and the switch operation.
Common Causes of E226
- Lower cavity latch position switch failed
- Wire between the lower latch switch and the shared control module broken
- Connector at the lower latch assembly loose
🔧 One Safe Check You Can Try
Cut power at the breaker for two minutes to perform the reset the manual specifies. Note whether both cavities come back, because on a double oven the disabling of heating is the part that tells you how serious this is.
⚠ Why You Shouldn't Go Further Than That
- All heating elements are disabled, so on a double oven this takes out both cavities rather than only the one reporting the fault.
- The lower latch assembly sits behind the fascia of a stacked appliance, which is the most awkward access point on a built-in oven.
- A switch replaced without checking its adjustment reports the same ambiguous position the old one did.
- The wiring Bosch asks to check runs through the hottest part of the frame, where insulation damage is common and easy to miss.
