Bosch wall ovens — single, double, combi-steam, and speed models — display codes on the TFT or LED panel. The E011 (temperature sensor open) and E012 (temperature sensor short) codes are the most common, usually caused by a failing NTC thermistor inside the cavity.
Self-clean cycle failures (E025, E030) appear when the door-lock mechanism doesn’t engage or the cavity doesn’t reach the required pyrolytic temperature. Check that nothing is blocking the door latch before resetting.
Control-board codes (E100+) are less frequent but more costly. If the display flickers or the code appears intermittently, document the exact sequence — our oven repair technicians use that pattern to isolate the faulty relay or capacitor without replacing the entire board.
